+Here are the steps for installing gpsd and verifying its performance:
+
+0. gpsd has a core set of prerequisites that are required for any
+configuration of the package, and then additional features and tests
+have additional prerequisites.
+
+Necessary components for any build:
+
+C compiler		-> gpsd and client library are written in C
+Python			-> some code is generated from python scripts
+Python GTK-2 binding	-> the main test client, xgps, needs this
+
+The C code depends on one non-C99 feature: anonymous unions.  We could
+eliminate these, but the cost would be source-level interface breakage
+if we have to move structure members in and out of unions.
+
+You will need Python 2.6 or 2.4+ & simplejson.  The Python code in
+GPSD is 2.4-compatible except that you need either the json library
+module from 2.6 or the functionally equivalent simplejson backport.
+Note that while Python is required to *build* GPSD (the build uses
+some code generators in Python), it is not required to run the service
+daemon.  In particular, you can cross-compile onto an embeddeed system
+without having to take Python with you.
+
+Having the following optional components on your system will enable
+various additional capabilities and extensions:
+
+C++ compiler	       -> libgpsmm C++ wrapper for the library
+pthreads library       -> support for PPS timekeeping on serial GPSes
+DBUS                   -> gpsd will issue DBUS notifications 
+ncurses                -> a test client and the GPS monitor depend on this
+libusb-1.0.x or later  -> better USB device discovery
+Qt + qmake             -> libQgpsmm depends on this
+
+If you have libusb-1.0.0 or later, the GPSD build will autodetect
+this and use it to discover Garmin USB GPSes, rather than groveling
+through /proc/bus/usb/devices (which has been deprecated by the
+Linux kernel team).
+
+For working with DBUS, you'll need the DBUS development
+headers and libraries installed.  Under Debian/Ubuntu these
+are the packages ibdbus-1-dev and libdbus-glib-1-dev.
+
+For building from the source tree, or if you change the man page
+source, xslt and docbook xsl style files are used to generate nroff
+-man source from docbook xml.  The following packages are used in this
+process:
+
+libxslt                -> xsltproc is used to build man pages from xml
+docbook-xsl            -> style file for xml to man translation
+
+The build degrades gracefully in the absence of any of these. You should
+be able to tell from configure messages which extensions you will get.
+
+Under Ubuntu and most other Debian-derived, an easy way to pick up
+the prerequisites is: "apt-get build-dep gpsd"
+
+If you are going to modify the build, you will need these:
+
+autoconf 2.61 or later
+automake 1.10 or later
+libtool 2.26 or later
+pkg-config
+
+Once you have fetched the software prerequisites:
+
+1. Start by making sure you can get data from your GPS, otherwise the later
+steps will be very frustrating.  In this command
+
+      stty -F /dev/ttyXXX ispeed 4800 && cat </dev/ttyXXX
+
+replace ttyXXX with the filename of the port.  This will probably be
+either /dev/ttyUSB0 or /dev/ttyS0.  When you run this command, you
+should see text lines beginning with $ come to stdout (possibly after
+a short initial burst of binary garbage).  If you don't see this, you
+may have OS-level problems with your serial support, but more likely
+have the wrong device.  Look again.
+
+2. Ensure that device permissions will enable gpsd to read from and
+write to GPS devices even after it drops root privileges.  If you are
+running Fedora Core or Ubuntu you can skip this step, as the stock
+configuration has the right properties.
+
+gpsd requires two things: (1) that GPS devices have group read and
+write enabled, and (2) all of them are have the same group ID as a 
+prototypical device, typically /dev/ttyS0 under Linux or /dev/tty00
+under *BSD. It does not actually matter what the owning group is, 
+as gpsd will look this up on startup.  Alternatively, (3), you can
+set a fallback group with the enable-gpsd-group in case the prototype
+is not found: this should be the "dialout" group (or functional equivalent) 
+that has write access to serial devices.
+
+Before dropping privileges, gpsd will ensure that it has access to
+devices given to it on the command line by forcing their group read
+and write permissions on.
+
+On a Linux with udev, check the files in /etc/udev/permissions.d to
+ensure that /dev/tty* devices are all created with the same group 
+and with 0660 permissions.
+
+When gpsd drops privileges, its default is to set uid to 'nobody' and
+group to the owning group of the prototype device (the configure
+option --enable-gpsd-user=foo will cause gpsd to change to 'foo'
+instead).
+
+If your system has the Linux hotplug facility installed you can skip
+the permission-setting part; the hotplug scripts will force the
+permissions for you.  You still have to make sure all the tty devices
+are in the same group.
+
+3. Install prerequisites
+
+Under Debian and Ubuntu ou can get all the build prerequisites
+installed with "apt-get build-dep gpsd".
+
+Note: if you are going to use the RTCM-104 support, you should compile
+with gcc4; if you don't have it installed as your default 
+compiler, do this by specifying CC=gcc4 before the configure
+command.  The rtcm2.c file confuses the gcc-3.4.[23] optimizer
+at -O2 level, making it generate incorrect code.
+
+4. Build gpsd from source (skip this step if you have installed GPSD 
+from a binary package).  As usual, the sequence is:
+
+     ./configure && make
+
+Mac OS X users may need to do "./configure --x-includes=/usr/X11R6/include"
+
+5. Start gpsd.  You'll need to give it as an argument a path to 
+a serial or USB port with a GPS attached to it.
+
+6. Once gpsd is running, telnet to port 2947. You should see a
+greeting line that's a JSON object describing GPSD's version.
+Now plug in your GPS (or AIS receiver, or RTCM2 receiver).
+
+7. Type '?WATCH={"enable":true,"json"};' to start raw and
+watcher modes.  You should see lines beginning with '{' that are
+JSON objects representing reports from your GPS; these are packet
+translations in GPSD protocol.
+
+8. Start the xgps client.  Calling it with no arguments should do the right 
+thing.  You should see a GUI panel with position/velocity-time information,
+and a satellite display.  The displays won't look very interesting until 
+the GPS acquires satellite lock.
+
+9. Now that you've verified that the code is working, "make install" 
+will install it it in the system directories.  "make uninstall" will
+undo this.
+
+(You won't need to "make install" if you installed from a binary package.)
+
+10. To enable hotplugging of USB GPSes under Linux, do a 'make udev-install' or
+equivalent to put the appropriate udev rules and wrapper files in place.
+
+11. Check out the list of supported hardware at 
+
+   http://gpsd.berlios.de/hardware.html
+
+If your GPS isn't on the list, please send us information to add a new
+line to the table.  Directions are included on that page.
+
+We can also use updates of the latest version number known to work with
+hardware already supported.
+
+12. Note for small embedded systems and those without threading.  It is
+possible to build gpsd without thread support if you configure with
+--disable-pps.  You'll lose support for updating the clock from PPS pulses.
+
+13. Note for systems using DBUS: gpsd includes support for shipping fixes
+as DBUS notifications, but it is not compiled in by default.  Configure 
+with the option "--enable-dbus" to get it working.
+
+14. The distribution includes a PHP script that you can use to
+generate a PHP status page for your GPS.  You will need php and php-gd
+installed.  To install it, copy the file 'gpsd.php' to your HTTP
+document directory.  The first time it's invoked, it will generate a
+file called 'gpsd_config.inc' containing configuration information;
+edit to taste.  Note that for the Google Maps feature work you need
+to set a valid Google API key in your config file.
+
+15. libQgpsmm is a Qt version of the libgps/libgpsmm pair. Thanks to
+the multi-platform approach of Qt, it allows the gpsd client library
+to be available on all the Qt supported platforms.  Please see
+http://qt.nokia.com/doc/4.6/supported-platforms.html for a status of
+Qt supported platforms as of version 4.6.
+
+You can build libQgpsmm if you have qmake and Qt (specifically the
+(specifically QtCore and QtNetwork modules) version 4.5.3 or higher.
+You will also need a C++ compiler supported by Qt (tested on GCC
+4.4.0/mingw on Windows and GCC 4.1.2 on linux).
+
+Building is done through a standard Qt .pro project file:
+- Go to the libQgpsmm subdirectory of gpsd and execute "qmake" 
+  to create the Makefiles
+- execute "make" to build the library
+- execute "make install" or equivalent to copy libgpsmm.h and the library 
+  to the appropriate location for your platform.
+
+Specifically for linux: You can specify the installation prefix by
+running "qmake PREFIX=<installation_root>". Default value is
+"/usr/local".
+
+Please refer to Qt's documentation at
+http://qt.nokia.com/doc/4.6/platform-specific.html for platform specific
+building documentation
+
+16. There are regression tests to verify proper operation of gpsd, and
+it can be useful to run these to verify that all is well.  To run the
+regression tests, first build gpsd from sources, and then run "make
+check".  It is not necessary to install first, but you do need
+to have "." in your $PATH to run regressions uninstalled.  Python is
+required for regression tests.
+
+17. If you installed from a .deb under Debian or a Debian-derived 
+system, you may need to `dpkg-reconfigure -plow gpsd' to enable the
+hotplug magic ("Start gpsd automatically").
+
+18. Note for people using gpsd as time source for ntpd: In case you're
+using dhcp3-client to configure your system, make sure you disable
+/etc/dhcp3/dhclient-exit-hooks.d/ntp as dhclient would restart
+ntpd with an automatically created ntp.conf otherwise - and gpsd
+would not be ablt to talk with ntpd anymore.

+* Tue Jul 13 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.95
+  The autonomous robot submarine total world domination release!
+  Rationalize clearing and generation of DOPs, this makes epx/epy much
+  more generally available. Fixed the test productions for the udev
+  magic and added a troubleshooting note in INSTALL. cgps now displays
+  epx/epy rather than eph. Speed is now always reported if our last
+  two fixes were good, even if the GPS didn't compute it.  Reading
+  packets from UDP datagrams by specifying a listening address and
+  port is now supported, and the regression-test driver cam now be
+  told to force this with -u; this enables regression testing in
+  chroot jails where access to ptys is locked out. AIS code now
+  interprets message type 6 and 8 application IDs correctly as a
+  Designated Area Code and Functional ID pair. gpspipe has a new -T
+  option for setting the timestamp format.  xgpsspeed is completely
+  rewritten in Python, eliminating some dependencies on ancient X
+  libraries.  We now ship a Qt binding for the client library. Note
+  a GCC 4.2.1 optimizer bug.  gpsdcode now uses | as a field separator
+  in -c mode, as string fields can contain commas.  Corrected error
+  or reporting of AIS rate-of-turn fields.
+
+* Tue Apr 20 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.94
+  Error-checking in the 50bps subframe code has been greatly improved.
+  The Garmin GPS driver can now use libusb, if it is present, to do
+  device discovery. The libgps library has been split apart; the
+  service functions used by the daemon now live in libgpsd. This
+  will shave some code volume from GPSD client applications.  A packaging
+  error that resulted in xgps not being shipped in 2.93 has been
+  corrected. We now have stronger checking for valid ephemeris before
+  extracting the leap-second offset; they should prevent many cases
+  where gpsd might previously have used an invalid leap-second offset.
+
+* Fri Apr 16 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.93
+  Support for JSON dumping and parsing of AIS message types 25 and 26,
+  not yet observed in the wild on AISHub. Fix Debian bug #569703.  by
+  removing non-streaming mode from the Python exerciser. Fix Debian
+  bug #572900 by unsetting the appropriate in-use flag in the device
+  array.  Change the libgps default from old protocol to JSON. Add a
+  close() method to the C++ binding. Try to recover better from
+  sporadic cases of false matches to Trimble packet format from a SiRF
+  binary datastream. gps_poll() now returns -1 with errno not set when
+  the gpsd socket closes. TPV now refrains from reporting fields the
+  fix quality won't support. gpsmon option for listing device types is
+  now -L to -l can be used to enable logging (to stay consistent with
+  the l command). There is new FAQ material on improving fix and time
+  reference accuracy. New sections have been added to NMEA.txt on
+  error status indications and satellite IDs.  New POLL command brings
+  back polling-mode operation.  A Client-HOWTO has been added to the
+  documentation. gpsd no longer eats CPU when a device is unexpectedly
+  unplugged. Support for the TNT revolution is back (run mode only).
+  There is now a gpsdfake diagnostic tool that fakes being gpsd shipping
+  arbitrary specified data to clients.
+
+* Wed Mar 3 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.92
+  Fix a packaging error.  The new Python library module was
+  inadvertently omitted from the 2.91 tarball.  Also, improve the json
+  import test slightly.
+
+* Mon Mar 1 2010 Eric S. Raymond <esr@snark.thyrsus.com> - 2.91
+  We have support for NMEA GLONASS sentences, and a regression test.
+  Clients now get a DEVICE notification on every driver switch.  It is
+  possible to specify a TCP/IP AIS feed such as AISHub as a data
+  source. Serious bitrot in the NTRIP support has been fixed - it was
+  probably nonfunctional for several releases before this.  Fixed
+  buggy display of satellite-used flags in cgps.  xgps is replaced by
+  a rewrite in Python that uses pygtk, eliminating a dependency on
+  Motif; also, it now displays AIS information. Uniform treatment of
+  display-unit defaulting and -u in xgps, cgps, and lcdgps. Support
+  for AIS message types 25 and 26.  Support for IPv6.  A numeric
+  instability in the earth_distance() function affecting track error
+  modeling has been fixed. Old protocol has been removed from the
+  daemon; the library still speaks it.
+
+* Fri Dec 4 2009 Eric S. Raymond <esr@snark.thyrsus.com> - 2.90
+  GPSD-NG, the new JSON-based command protocol, is now deployed; as a
+  consequence, AIS is now fully supported in both daemon and client.
+  Detection of end of a fix-reporting cycle is now reliable;
+  accordingly data is accumulated from cycle start and the "J"
+  (nojitter) option on both server and client side is gone. We have
+  abandoned the gpsflash subproject since it has become apparent that
+  we can't do it without more vendor cooperation than we're likely to
+  get. Increase major version of shared library due to significant API
+  change. Added new driver for Motorola Oncore receivers, with help
+  from Håkan Johansson. gpsfake can now accept multiple logfiles,
+  interleaving test sentences from each.  gpsd now accepts error
+  estimates from the NMEA $GPGBS sentence.
+
+* Wed Mar 18 2009 Eric S. Raymond <esr@snark.thyrsus.com> - 2.39
+  Fixed potential core dump in C client handling of "K" responses.
+  Made device hotplugging work again; had been broken by changes in udev.
+  Introduced major and minor API version symbols into the public interfaces.
+  The sirfmon utility is gone, replaced by gpsmon which does the same
+  job for multiple GPS types. Fixed a two-year old error in NMEA parsing
+  that nobody noticed because its only effect was to trash VDOP values from
+  GSA sentences, and gpsd computes those with an internal error model
+  when they look wonky.  cgpxlogger has been merged into gpxlogger.
+  Speed-setting commands now allow parity and stop-bit setting if the
+  GPS chipset and adaptor can support it. Specfile and other packaging
+  paraphenalia now live in a packaging subdirectory.  rtcmdecode becomes
+  gpsdecode and can now de-armor and dump AIDVM packets. The client
+  library now works correctly in locales where the decimal separator is
+  not a period.
+
+* Tue Feb 10 2009 Eric S. Raymond <esr@snark.thyrsus.com> - 2.38
+  Regression test load for RoyalTek RGM3800 and Blumax GPS-009 added.
+  Scaling on E error-estimate fields fixed to match O. Listen on
+  localhost only by default to avoid security problems; this can be
+  overridden with the -G command-line option. The packet-state machine
+  can now recognize RTCM3 packets, though support is not yet complete.
+  Added support for ublox5 and mtk-3301 devices. Add a wrapper around
+  gpsd_hexdump to save CPU. Lots of little fixes to various packet
+  parsers. Always keep the device open: "-n" is not optional any more.
+  xgpsspeed no longer depends on Motif. gpsctl can now ship arbitrary
+  payloads to a device. It's possible to send binary through the
+  control channel with the new "&" command. Experimental new driver
+  for Novatel SuperStarII. The 'g' mode switch command now requires,
+  and returns, 'rtcm104v2' rather than 'rtcm104'; this is design forward
+  for when RTCM104v3 is fully working.
+
+* Sun Feb 17 2008 Chris Kuethe <ckuethe@mail.berlios.de> - 2.37
+  The C++ bindings, Garmin USB support, and multiple instances of ntp
+  pps thread starting were fixed. Handling of odd PPS signals was
+  improved. The eye candy in the PHP visualizers was fixed.
+
+* Tue Jan 1 2008 Eric S. Raymond <esr@snark.thyrsus.com> - 2.36
+  Urgent fix to leap-day calculation affecting dates from today to
+  28 Feb on generic NMEA GPSes, Zodiacs, and SirFs emitting message 0x62.
+  Integrated Garmin Simple Text Protocol driver from Peter Slansky.
+  Minor fixes in error modeling and a better NaN guard stabilize the
+  Trimble regression tests.  Remove the wired-in NTP time offset from the
+  NMEA driver, this could only have worked by accident and should be
+  set in ntpd.conf. Integrated Ashtech driver from Chris Kuethe.
+
+* Mon Dec 10 2007 Eric S. Raymond <esr@snark.thyrsus.com> - 2.35-1
+  Navcom driver merged. Removed -d -f and -p options of gpsd; these
+  have been undocumented for a while.  Make gpsd play well with pkgconfig.
+  Incorrect computation of VDOP when GPSes didn't supply it has been fixed.
+  The xgps code has been revamped and now has a much nicer interface.
+  Add -b (no-configuration) option as a sadly clumsy workaround for some
+  problems with Bluetooth receivers.  Added tests for Haicom-305N and Pharos
+  360; separated out the tests for the unstable Trimble drivers.
+  32-vs-64-bit problems in the regression tests have been solved.
+
+* Thu Dec 14 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.34-1
+  Fix for byte-swapping of Zodiac control messages on big-endian hardware.
+  Disable iTalk by default and note that it needs to be tested.  Command line
+  arguments can now be DGPSIP or NTRIP URLs; -d is deprecated. Added udev
+  rules.  Address excessive processor and memory utilization on SBCs; it's
+  now possible to configure compile-time limits on the number of devices
+  and client sessions.  Eliminate use of fuser(1) in gpsfake.  Get gpsd
+  working with EarthMates again, this had been broken since 2.15.  Massive
+  string safety audit and OpenBSD port by Chris Kuethe.  J command added.
+  The gpsctl and gpscat tools and the gpsd.phps script were added.  Switched
+  to lesstif from openmotif.  Better autodetection of DLE-led packet
+  protocols (notably TSIP and Garmin binary) and of SiRFStar I and III
+  devices.  Fixed buggy parsing and generation of PGRME.
+
+* Fri Jun  9 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.33-1
+  Fix bad unit conversion in V output.  Clean up some man-page messes.
+  Fixed buggy libgps parsing of multiple responses.  It's now possible
+  to lock gpsd to a fixed speed at compile time for embedded use.  Added
+  NTRIP support, thanks to Ville Nuorvala.  O command now ships an
+  explicit mode field.
+
+* Sun Mar 12 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.32-1
+  Cleanup of the xgps layout, and minor memory-leak fixes for xgps.  Fix
+  to cope with Antares uBlox by Andreas Stricker.  Minor fix to libgps
+  cgpxlogger.  Merge cgpxlogger and gpxlogger documentation onto
+  the xgps(1) manual page and rename it gps(1).
+
+* Fri Feb 17 2006 Eric S. Raymond <esr@snark.thyrsus.com> - 2.31-1
+  Now builds and runs under Cygwin.  Correct the speed units in
+  synthetic NMEA.  Slightly better time handling under NMEA.  Daemon
+  now builds with all but NMEA disabled.  Update the leap-second
+  offset. cgpxlogger introduced.  Upgrade gpxlogger to DBUS 0.60
+  conformance.  Jason von Nieda's patch may fix the chronic TSIP
+  driver problems.
+
+* Wed Sep 14 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.30-1
+  Prevent core dump on -d option.  The .log extension is no longer required for
+  test loads.  cgps and xgps now have configurable latitude/longitude formats
+  via the -l option.  Introduced new 'g' command that allows clients to
+  specify whether they want GPS or RTCM104 information.
+
+* Fri Aug 19 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.29-1
+  Added Sony CXD2951 support, untested.  All error estimates are
+  now nailed to 95% confidence interval.  Added rtcmdecode and its
+  documentation; also, gpsd can now monitor serial devices emitting
+  RTCM104 and display differential-GPS data in a readable format.
+  Added dangerous alpha version of gpsflash.  Work around a nasty bug
+  in SiRFStar III firmware version < 3.1.1.  Added support for True
+  North Technologies Revolution 2X Digital compass.  Added the
+  gpxlogger client for systems with DBUS support and the gpspipe
+  and cgps clients for general use.
+
+* Wed Jul  6 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.28-1
+  The 2.27 source tarball somehow got truncated on upload.
+  Due to procedural mechanics at berlios.de, shipping a new release
+  seems to be the least painful way to recover.  This release is
+  identical to 2.27 except the roadmap stuff has been added to TODO.
+
+* Wed Jul 06 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.27
+  Arrange for the daemon to remove its pid file on exit.  Fix some
+  buffering problems with the Python side of the hotplug interface.
+  gpsfake can now run sessions under a monitor like Valgrind.  Most
+  of the gpsfake logic now lives in a module that can be used to write
+  other test loads; its progress baton is now optional.  Fixed
+  some minor bugs found by valgrind audit, including (1) a slow
+  memory leak, (2) a possible but unconfirmed file-descriptor leak,
+  and (3) a subtle error in the channel-assignment logic that only
+  showed up with multiple sessions active.  In fact, the daemon code
+  no longer uses dynamic-memory allocation at all.  Also, the code
+  no longer relies on FIONREAD working.  The track error field in the
+  O response is now computed.  The project website has some new eye candy.
+  Client connections now time out when the mode is neither raw nor watcher.
+  Fixed a core-dump that could happen if C, B or I commands were issued
+  at odd times.
+
+* Wed Jun 22 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.26
+  Time DOP and total DOP are now passed on from GPSes that report
+  them.  Ensure longitude has a leading zero when <100, for
+  compatibility with gpsdrive.  Synchronous and thread hooks are now
+  separate in the client library.  Packet-sniffing on a new device no
+  longer holds up incoming data on already-connected ones.  There is
+  now a super-raw mode (R=2) that dumps a hex-encoding of every binary
+  packet received to the client; sirfmon uses it to operate through
+  the daemon if one is running.  Support for Trimble TSIP GPSes
+  merged. gpsfake now works with SiRF and Zodiac logs.  Python library
+  supports thread callbacks.  New -p option of gpsfake supports
+  regression testing of the daemon, and there is a test suite included
+  with the distribution.  PPS support is turned off, as there is some
+  pthreads problem that sometimes kills the daemon on pthreads exit.
+  Correct off-by-one error in GPZDA processing.  The code has been
+  audited and cleaned with splint (www.splint.org).
+
+* Sat May 21 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.25-1
+  Various signedness and scaling fixes and an OpenBSD port patch for the
+  Zodiac driver. Command-line arguments to gpsd are now treated as a default
+  device list; -f is still supported but deprecated.  sirfmon now tries not
+  changing the line speed first, so it syncs up much faster.  Prevent a
+  potential buffer overrun in the client library.  PPS-thread support is now
+  on by default.  Lots of documentation improvements. D-BUS broadcast support
+  by Amaury Jacquot.  Added Alfredo Pironti's thread-callback and C++
+  support.  gpsd no longer uses the system clock for anything, so it
+  can be used to set that clock.
+
+* Tue May 17 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.24-1
+  Crazy-speed bug is finally fixed. Autobauding now starts with the
+  current speed of the device, not the stored gpsd speed; this means
+  hunting only takes place when device and GPS speed aren't matched.
+  xgpsspeed unit-conversion bug introduced in 2.22 is fixed.  Satellite
+  display now really shows 12 channels, not just 11. Major improvements
+  in ntp notifications.
+
+* Wed May  4 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.23-1
+  For better security, the daemon now drops root privileges after startup.
+  gpsd-clients is now a separate RPM; this is helpful on lean systems
+  that don't run X.  The O command now reports speeds in meters per second
+  rather than knots, client code has been adjusted so there is no user-visible
+  change.  We now compute the missing components of DOP when using SiRF chips.
+  /dev/gps is no longer special; there is no default GPS device unless you
+  specify one.  The intermittent processor-hogging problem introduced by the
+  control-channel change in 2.21 has been solved.
+
+* Mon Apr 25 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.22-1
+  SiRF-binary driver can now get leap-second corrections from subframe data.
+  Device add/delete commands now send back OK or ERROR.  Error-modeling
+  corrections from the SiRF folks.  Higher precision in position reports.
+
+* Tue Apr 12 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.21-1
+  Add tag and timestamp to Y response.  Use computed geoid separation as
+  SiRF packet 42 is flaky.  Security fix: hotplug scripts now do device
+  add/removes through a separate local control channel.  True multi-device
+  support is in place.  When in watcher mode, device switches are announced.
+
+* Thu Mar 31 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.20-1
+  Rob Janssen's patches to fix timezone issues and improve cooperation
+  with NTP.  License changed to BSD so linking to libgps won't make people
+  nervous.  gpsprobe and gpsd.py are obsolete and have been removed, the
+  autoprobe and profiling capabilities in the daemon more than replace
+  them.  gpsprof now ships self-contained GNUPLOT scripts to stdout,
+  so they can be saved and redisplayed.  Zodiac sort of works again, but
+  occasionally spins madly during autobauding.
+
+* Sat Mar 26 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.19-1
+  Fix brown-paper-bag bug with NMEA parsing. Set SiRF GPSes to use
+  SBAS.  sirfmon now displays SBAS parameters, and is included in the
+  installed programs.  Add to FAQ a fix for spurious high speeds reported
+  in XTrac mode.  We now interpret GPZDA.  We no longer fudge a missing
+  ddmmyy in NMEA timestamps from the system clock, so replay will work better.
+
+* Wed Mar 23 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.18-1
+  First cut at cooperating with NTP.  Major library restructuring;
+  a fix is now a data structure of its own, and per-field timestamps
+  are gone. Use new 'o' command for watcher mode.  Compute some estimated
+  error bounds.
+
+* Wed Mar 16 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.17
+  Fix packet-engine problem that made disconnect/reconnect unreliable
+  (important!).  Fix bonehead error in interpretation of PGRME.  We
+  don't use O_SYNC (it turned out not to be reliable) so remove it to make
+  life easier under Mac OS X.  Allow gpsfake to accept subsecond cycle times.
+  Add a FAQ to the HTML documentation.  gps_poll() now handles multi-line
+  responses.  Add N command for switching driver modes.
+
+* Fri Mar 11 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.16-1
+  New F command allows changing the GPS device after startup time.
+  Hotplug scripts to go with it are now installed by the RPM.  The
+  Garmin probe is working.  The -T and -s options are gone.  We have
+  achieved zero configuration!
+
+* Wed Mar 02 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.15-1
+  A new packet engine autobauds much more quickly, and now iterates
+  over both 1 and 2 stopbits. Explicit support for FV18 (the -T f
+  option) is gone; instead, gpsd syncs with any 7N2 device and always
+  ships a suitable init string.  New E command, supporting the Garmin
+  position-error sentence or computing these numbers from DOP and an
+  error model. New U command reports climb/sink from GPSes that report
+  vertical velocity.  There is a prototype driver for SiRF-binary GPses,
+  invoked automatically when SiRF packets present themselves on the
+  wire after device open.
+
+* Fri Feb 25 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.14-1
+  Pass zero magnetic variation in generated NMEA from binary GPSes
+  correctly.  Use O_SYNC rather than timeouts to guarantee that
+  baud-rate change strings get to the GPS before changing the line
+  parameters.  Introduced I command.  Spatial scattergram plotting
+  moved from gpsprobe to gpsprof.
+
+* Mon Feb 21 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.13-1
+  Correct a bug in binary-protocol dumping (applies to Zodiac and
+  Garmin only).  Gary Miller's patch to deal gracefully with GPSes
+  like the Magellan EC10X that send only GPRMC and never GPGGA or
+  GPGSA, and thus never set mode or status fields.  Fixed buggy
+  handling of units options in xgps and xgpsspeed.  Bumped library
+  major version, since seen_sentences is now exposed and drivers have
+  more capabilities.  Stricter NMEA buffer validation.  Withdrew the
+  change that always passed up a timestamp; on SiRF receivers, the year
+  part is garbage when the PVT fields are garbage.  Can now recognize
+  SiRF GPSes.  Experimental baud-switching support for Zodiac.
+
+* Tue Feb 15 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.12-1
+  Fixed core-dump bug in processing of the GLL variant that does not
+  include an FAA Mode Indicator. When using the NMEA driver, gpsd now
+  hunts for a baud rate rather than requiring a fixed one to be set.
+  A new 'B' command returns the RS232 parameters, and a new 'C'
+  command returns the update cycle time.  Added gpsfake test harness.
+  Alpha driver for Garmin binary protocol added, requires Linux
+  garmin_usb kernel driver.  The daemon now always passes up a
+  timestamp for every sentence that has one, even if the PVT fields
+  aren't valid.
+
+* Thu Feb 10 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.11-1
+  Added gpsprof and the capability to generate GPS latency profiles.
+  gpsprobe now hunts through plausible baud rates when looking for NMEA
+  data from a GPS. The -b (baudrate) option fixes a speed, disabling
+  the baud-matching logic.  Also, gpsprobe can now recognize SiRF
+  protocol, though not speak it.  Fixed a math domain error in
+  gps.EarthDistance due to numeric blowup on points very close together,
+  and another in gps.MeterOffset() that was screwing up gpsprobe plots.
+
+* Tue Feb  1 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.10
+  Add -N option to explicitly foreground the daemon.  Fixed a bug
+  that was causing gpsd to keep reopening the GPS device after
+  leaving raw or watcher mode.  Fixed Gary Miller's core-dump bug.
+
+* Thu Jan 27 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.9-1
+  Python files restored to RPM.
+
+* Thu Jan 27 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.8-1
+  Embarrassing typo fix in gps.py. Avoid buffer overrun in xgps.c.
+  Plug Debian security bug 292347, CVE number CAN-2004-1388.
+  This version issued on an emergency basis without Python libraries,
+  which have packaging problems due to the 2.3/2.4 transition.
+
+* Fri Jan  14 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.7-1
+  More compiler-warning cleanups.  gps client name changed to xgps.
+  Added --speedunits option to xgpsspeed, --speedunits and --altunits
+  options to xgps.  Improved GPGSV parsing so it copes gracefully if
+  we start in the middle of a sequence.  Merged Petter Reinholdtsen's
+  fix for GPGSA lists with holes.  In xgps, satellites used in the
+  last fix are now dotted in the middle.  New -P option to create
+  pidfile.  Audited for potential buffer overruns, found and fixed
+  two.
+
+* Sat Jan 01 2005 Eric S. Raymond <esr@snark.thyrsus.com> - 2.6-1
+  Petter Reinholdtsen's fix for gps.py buffering.  Fix syntax errors
+  in udev scriptlets.  Clean up after GCC warning messages.  Drop use of
+  vsprintf, so we get a link-time error on systems that might produce
+  buffer overruns (all modern Unixes support vsnsprintf which is safe).
+
+* Thu Dec 23 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.5.1
+  Use gmtime instead of localtime when guessing the day or year of a date;
+  this avoids jitter in the day after 19:00 GMT.  Added -v option to dump
+  version and exit.  Commented out a crash-causing debug line in gps.py.
+
+* Thu Dec  9 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.4-1
+  Minor bugs in gpsd.py fixed.  M now returns 0 status if GPGSA not yet
+  seen; this change also fixes a bug where gpsd claimed it was confused
+  if GPGSA had not been seen and status was set.  RPM will now install
+  a udevd rule if the host system uses it.  Don't set the online flag
+  on activate.  HP port changes and -Wall cleanup.  James Cameron's
+  fixes to clean up gps.c and use X timeouts rather than alarms.
+
+* Mon Oct 25 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.3-1
+  Documentation and comment fixes.  Last two globals removed from
+  low-level interface; library should now be fully re-entrant. Mac OS X
+  port fixes. Q command fix from Robin L Darroch <robin@spade-men.com>.
+
+* Mon Oct 18 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.2-1
+  Documentation improvements.  BSD port fixes.  Bug fix: speed timestamp
+  wasn't initialized properly in libgps. Device is now an optional
+  command-line argument of gpsprobe, in line with the clients.  gpsd.py
+  now should handle fvwm devices correctly.  Values in gps data
+  panel are now labeled with units.  Attempted fix for 2.1 bug of DTR
+  not being pulled low on exit.
+
+* Thu Sep 30 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.1-1
+  Various internal cleanups, including fossil removal in the
+  configuration machinery.  FV-18, Tripmate, Earthmate and are now
+  enabled but can be disable with --disable-$NAME at configure time.
+  When you call configure with --disable-shared, libgps is linked
+  statically to the binaries (native libs are still linked
+  shared). Fixed buggy handling of -p option in gps.c and xgpsspeed.c;
+  it's now an optional command-line argument.
+
+* Thu Sep 16 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 2.0-1
+  Packaging fixes for 2.0 release.
+
+* Wed Sep  8 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.98-1
+  Only do one getdtablesize() call, otherwise we do several
+  getrlimits() each poll cycle.  TripMate is working.  gpsprobe now
+  deduces NMEA version.  Zodiac Earthmate seems to work.
+
+* Wed Sep 08 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.97-1
+  Removed PRWIZCH support (it still passes through in raw mode).
+  Build Motif-dependent programs conditionally.  Added gpsprobe.
+  Fixed a brown-paper-bag-bug in 1.96 RPM packaging.
+
+* Tue Aug 31 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.96-1
+  Implemented non-blocking writes to clients, so a stalled client
+  cannot stall gpsd.  Fixed a nasty array-overrun bug.  Timestamps
+  are now in ISO8601 format, with sub-second precision if the GPS
+  delivers that.  First cuts at Python interfaces included.  libgps.a
+  interface now bundles session fd into an allocated session block.
+  Automake-based build machinery from Jens Oberender; RPM now
+  installs shared libraries.  FV18 driver added. Offline timer in GPS.
+
+* Wed Aug 25 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.95-1
+  Fixed broken 'make dist', missing display.c and Tachometer.c
+  are in there now.
+
+* Tue Aug 24 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.94-1
+  Fix embarrassing bug -- watcher mode did not work for more than one
+  client at a time.  Y command now carries information about which
+  satellites were used in the last fix.  New timeout mechanism, no
+  longer dependent on FIONREAD.
+
+* Mon Aug 23 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.93-1
+  Fourth prerelease. Daemon-side timeouts are gone, they complicated
+  the interface without adding anything.  Command responses now
+  contain ? to tag invalid data. -D2 feature of 1.92 backed out.
+
+* Sun Aug 22 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.92-1
+  Third prerelease.  Clients in watcher mode now get notified when
+  the GPS goes online or offline.  Major name changes -- old libgps
+  is new libgpsd and vice-versa (so the high-level interface is more
+  prominent).  Specfile now includes code to install gpsd so it will
+  be started at boot time.  -D2 now causes command error messages
+  to be echoed to the client.
+
+* Sat Aug 21 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.91-1
+  Second pre-2.0 release.  Features a linkable C library that hides the
+  details of communicating with the daemon.  The daemon now recovers
+  gracefully from having the GPS unplugged and plugged in at any time;
+  one of the bits of status it can report is whether the GPS is online.
+  The gps and xgpsspeed clients now query the daemon; their code
+  for direct access to the serial port has been deliberately removed.
+
+* Sun Aug 15 2004 Eric S. Raymond <esr@snark.thyrsus.com> - 1.90
+  Creation of specfile.
+
+* Sun Mar 21 2004 Remco Treffkorn <remco@rvt.com> - ?
+  Without PRWIZCH sentence: sat. colors in gps according to ss, grey==lt20,
+  yellow==lt40 else green.
+  Added L Q and I to the protocol. Removed G and T.
+  Changed the timeout mechanism. Try to not return Lat/Lon/Alt if
+  validity is in doubt.
+
+* Thu Jan 29 2004 Remco Treffkorn <remco@rvt.com> - ?
+  Make applications null-terminate their resource lists.
+
+* Sat Dec 20 2003 Remco Treffkorn <remco@rvt.com> - ?
+  Removed <varargs.h> from netlib. Not needed, and new gcc does not support
+  it any more.
+
+* Wed Aug 20 2003 Remco Treffkorn <remco@rvt.com> - 1.10
+  Add install target. Fix clean target. Make GPS timeout configurable.
+  Make xgpsspeed build with Apple's X11.
+  Make sure that we don't segfault if the NMEA is badly formed.
+
+* Mon Aug 18 2003 Remco Treffkorn <remco@rvt.com> - ?
+  Use cfset[io]speed() to set speed in serial.h. Glibc is quite insane
+  and I am tired to chase it, so I give up. Hope this works for BSD.
+  Set status and mode 0 after GPS timeout (5 sec) - Cougar <cougar@random.ee>
+
+* Sun Feb 16 2003 Remco Treffkorn <remco@rvt.com> - 1.09
+  Include sys/time.h in gpsd.c for struct timeval.
+
+* Sun Nov 03 2002 Remco Treffkorn <remco@rvt.com> - ?
+  G or g command returns six-digit Maidenhead grid square (like FN12fx)
+
+* Thu Oct 03 2002 Remco Treffkorn <remco@rvt.com> - 1.08
+  Added sockopt SO_REUSEADDR to netlib.c passive_sock.
+
+* Tue Feb 05 2002 Remco Treffkorn <remco@rvt.com> - 1.07
+  em.c uses <time.h> (as it should). Removed some <sys/time.h>
+  where they were not needed.
+  Russ Nelson: Improved Earthmate support: added state machine for
+  EARTHA recognizer, removed alignment problems seen on ARM architecture.
+  Added setsockopt to add SO_REUSEADDR, so that
+  gpsd can stop and immediately restart.  Added support for bitrates
+  higher than 38400, needed for the SIRF chipset.
+  Derrick: my patch causes longitude when under 100 degrees to be printed
+  zero-padded as needed, the latitude same deal under 10, fixes the GGA
+  sentence to not erroneously print fix type (2/3) instead of fix quality,
+  and calculates fix type correctly.
+
+* Fri Aug 11 2000 Remco Treffkorn <remco@rvt.com> - 1.06
+  Change from C++ (/) to C comments (/* */)for compatibility.
+  Added -n (need init) flag.
+  Don't init unless lat/lon specified.
+  Remove gps.mayko.com as the default hostname.
+
+* Fri May 12 2000 Remco Treffkorn <remco@rvt.com> - 1.05
+  (even though version.h says 1.04)
+  Added some includes to xgpsspeed.c for portability.
+  Fix problem with flags being overwritten, and using the wrong port
+  variable also in xgpsspeed.c
+  Add a note about Y2K compatibility fix.
+  Pass latitude and longitude into em_init().
+
+* Fri Mar 17 2000 Remco Treffkorn <remco@rvt.com> - 1.02
+  (even though version.h says 1.01)
+
+* Sun Mar 05 2000 Remco Treffkorn <remco@rvt.com> - 1.01
+  Updated to IANA port.
+  Fixes to DGPS support.
+
+* Sun Jan 02 2000 Remco Treffkorn <remco@rvt.com> - 1.0
+  Added DGPS fixes from Curt Mills. (See README for contact info.)
+
+* Mon Dec 13 1999 Remco Treffkorn <remco@rvt.com> - 0.99dgps
+  Added minimal DGPS support by Derrick J Brashear
+
+* Sat Jul 17 1999 Remco Treffkorn <remco@rvt.com> - 0.99
+  Rockwell binary is now translated to NMEA format, so that
+  clients like gps will work with an EarthMate.
+  Added speedometer application. Thanks to Derrick J Brashear
+  for his work (see README for contact info).
+
+* Thu Mar 04 1999 Remco Treffkorn <remco@rvt.com> - 0.96
+  Changed EarthMate support. Rockwell binary is now almost properly
+  supported. Only the minimum required information is extracted.
+
+* Sat Feb 06 1999 Remco Treffkorn <remco@rvt.com> - 0.95
+  Added support for EarthMate receivers. Since I do not have one, this is
+  untested.
+  If it works, it does the following: You start gpsd with a baudrate of 9600
+  and give it the -Te option. If gpsd gets the EartMate it will enable the
+  receiver and then attempt to switch it into NMEA mode. If the EarthMate id
+  is not received, but a binary data header is received, then we will try to
+  switch NMEA too.
+
+* Sun Jan 24 1999 Remco Treffkorn <remco@rvt.com> - 0.94
+  Y2K compliant ;-)  (... is NOT. Look for "FIXME:" in nmea_parse.c)
+
+* Tue Jan 27 1998 Remco Treffkorn <remco@rvt.com> - 0.93
+  using GNU autoconf now.
+  combined gpsd + gpsclient. No more init files, command line only.
+
+* Tue May 13 1997 Remco Treffkorn <remco@rvt.com> - 0.9
+  some cleanups in the ini code. version 0.9 ...
+
+* Fri Apr 25 1997 Remco Treffkorn <remco@rvt.com> - 0.8
+  version 0.8, some bug fixes. New MODE member, STATUS member changed.
+
+* Mon Apr 21 1997 Remco Treffkorn <remco@rvt.com> - 0.7
+  released version 0.7

+COPYRIGHT
+=========
+
+This software (gpsd) released under the terms and conditions of the BSD
+License, a copy of which is included in the file COPYING.
+
+GENERAL
+=======
+
+gpsd is a userland daemon acting as a translator between GPS or
+Loran-C receivers and clients. gpsd listens on port 2947 for clients
+requesting position/time/velocity information.  The receivers are
+expected to generate position information in a well-known format -- as
+NMEA-0183 sentences, SiRF binary, Rockwell binary, Garmin binary
+format, or other vendor binary protocols.  gpsd takes this
+information from the GPS and translates it into something uniform and
+easier to understand for clients.  The distribution includes sample
+clients, application interface libraries, and test/profiling tools.
+
+There is a project site for gpsd at <http://gpsd.berlios.de/>.
+Look there for updates, news, and project mailing lists.  See that
+website for a list of GPS units known to be compatible.
+
+See the file INSTALL for installation instructions and some tips on
+how to troubleshoot your installation.
+
+Distro integrators: An RPM spec file is included in the gpsd
+distribution.  It wants to set up a hotplug script to notify gpsd
+when a potential GPS device goes active and should be polled.  The
+goal is zero configuration; users should never have to tell gpsd how
+to configure itself.  If you can't use RPM, use what you see in the
+specfile as a model.
+
+1.X CREDITS
+===========
+
+Remco Treffkorn designed and originated the code.
+
+Russ Nelson maintained gpsd for a couple of years.
+
+Carsten Tschach's gpstrans-0.31b code was the original model for nmea_parse.c.
+
+Bob Lorenzini <hwm@netcom.com> provided testing and feedback.
+
+Brook Milligan <brook@trillium.NMSU.Edu> combined gpsd and gpsclient
+into one package and autoconfiscated it.
+
+Derrick J. Brashear <shadow@dementia.org> (KB3EGH) added code for the
+EarthMate DeLorme. He also added "incredibly gross code to output
+NMEA sentences" (his own words :-) He also did the first cut at
+DGPS support (see http://www.wsrcc.com/wolfgang/gps/dgps-ip.html), 
+for the Earthmate.
+
+Curt Mills <BowHunter@mail.com> (WE7U) furthered the dgps support,
+writing the portion for other GPS receivers.
+
+None of these people are active in 2.X, through Remco de-lurks on the
+mailing list occasionally.
+
+2.X CREDITS
+===========
+
+Eric S. Raymond drastically rewrote this code to clean it up and extend it.
+The 2.X architecture has become significantly different and far more 
+modularized. His new features include:
+   * Documentation (what a concept!)
+   * Cleaned up, simplified command-line options.
+   * Now understands the GLL (Geographic position - Latitude, Longitude)
+     sentence from NMEA 3.0. 
+   * Now parses both the NMEA 3.01 and pre-3.01 variants of the VTG sentence 
+     correctly.
+   * New 'y' command supports satellite location -- it should no longer ever
+     be necessary for clients to go to raw mode unless they want to monitor and
+     and log the NMEA stream itself.
+   * New 'w' command toggles 'watcher' mode. In watcher mode gpsd ships
+     a gpsd-style response for each incoming sentence as if the client
+     had just sent all commands that asked for data contained in the sentence.
+   * New 'x' command allows the client to query whether or not the GPS
+     is on-line.
+   * Massive refactoring -- one main loop now calls a self-contained
+     driver object for each type.
+   * The GPS-bashing code the daemon uses can now be directly linked as a
+     library, libgpsd(3). 
+   * C and Python libraries are available to encapsulate the client side of
+     querying gpsd, see libgps(3).
+   * Cleaned-up error reporting, we don't use syslog when running in foreground
+     but send all error and status messages to the tty instead.
+   * Added -n option to do batch monitoring of GPSes.
+   * xgpsspeed is working again; xgps has been seriously reworked and improved.
+   * RPMs which include installation of gpsd to start up at boot time 
+     are available.
+   * New gpsprobe program probes the capabilities of GPSes and generates
+     error scattergrams from fixes.  (Later this moved to gpsprof.)
+   * Autobauding, self-configuration, and hotplugging.  gpsd can now get
+     its device from a hotplug script, and figures out itself which baud 
+     rate to use and what the GPS's device type is.
+   * More new commands: 'I', 'U', 'E', 'B', 'Z'. See the docs.
+   * Support for SiRF binary mode.
+   * Support for RTCM104 and AIVDM.
+   * Support for multiple devices.
+   * Other test tools -- gpsfake, gpscat.
+
+Chris Kuethe <ckuethe@mail.berlios.de> maintains the OpenBSD port, shipped
+the 2.34 release, is our SiRF and low-level protocols expert, and does a 
+lot of general hacking and support.
+
+Gary Miller <gem@rellim.com> wrote the driver for Garmin binary protocol.
+
+Amaury Jacquot <sxpert@esitcom.org> added DBUS support.
+
+Ville Nuorvala <vnuorval@tcs.hut.fi> wrote the NTRIP support.
+
+We are delighted to acknowlege the assistance of Carl Carter, a field
+application engineer at SiRF.  He assisted us with the correction and
+tuning of the SiRF binary-protocol driver, shedding a good deal of 
+light on murky aspects of the chip's behavior.
+
+We are also delighted to acknowlege the assistance of Timo Ylhainen, VP of
+Software Operations at Fastrax. He clarified a number of points about
+the iTalk protocol, helping to further development of iTalk support.

+This is the gpsd to-do list.  If you're viewing it with Emacs, try

+will unfold them again.
+
+For contribution guidelines and internals documentation, please see
+<http://gpsd.berlios.de/hacking.html>.
+
+The list of bugs exposed by gpsd in other software has moved to
+<http://gpsd.berlios.de/upstream-bugs.html>.
+
+** Bugs in gpsd and its clients:
+
+*** Tracker bugs
+
+See the GPSD bug tracker at https://developer.berlios.de/bugs/?group_id=2116
+but don't be surprised if it's empty or very sparse.  Our rate of new defects
+per month is quite low.
+
+*** Driver issues
+
+**** gpsctl -b should work on UBX, but does not.
+
+Presently this means there's no way to kick a UBX into returning
+binary data.
+
+** Ports
+
+*** Windows port
+
+Partially complete. David Ludlow <dave@adsllc.com> is working on it.
+
+** To do:
+
+*** Bump MAXCHANNELS to support GPS/GLONASS devices
+
+This will require a major soname bump. Probably goes with the API 
+changes on the Future page. Here's a test log for a GPS/GLONASS device,
+the Geostar Geos 1M: <http://old.nabble.com/new-gps-report-to29115582.html>.
+
+*** Write advanced features for TNT Revolution device
+
+The baud-rate switcher in the TNT driver needs to be tested.
+
+gpsmon could support a number of TNT configuration commands, including
+unit changes. See http://gpsd.googlecode.com/truenorth-reference.pdf
+for possibilities.  
+
+Jon Schlueter has one of these on a flock machine, so testing 
+shouldn't be difficult.
+
+*** Finish gpssim
+
+It's blocked on skyview computation.
+
+*** Complete and test the speed/parity/stopbit methods in the drivers
+
+These are used for the '?DEVICE' command.  All work for 8N1.
+
+**** superstar2: not implemented (driver is unfinished)
+**** italk: not implemented (but could be)
+**** tsip: speed tested, parity and stop-bit switching not tested
+**** sirf: speed tested, parity and stop-bit switching not tested
+**** evermore: speed tested, rejects parity/stopbit setting
+**** ubx: fully implemented, parity and stop-bit switching not tested
+**** zodiac: fully implemented, not tested
+**** navcom.c: speed tested, rejects parity/stopbit setting
+
+SiRF, UBX, TSIP, and even Zodiac can support non-8N1 modes; these need
+to be tested.
+
+*** Command to ship RTCM corrections to a specified device
+
+At the moment, if a GPS accepts RTCM corrections and they are
+available, gpsd ships them to the serial device from which the GPS is
+reporting fix data.  Some GPSes have auxiliary ports for RTCM; 
+there should be a (privileged) command to redirect RTCM connections.
+
+*** Per-driver restore of changed config settings on exit.
+
+This is a solved problem for generic NMEA, EverMore, TripMate,
+EarthMate, TNTC, Zodiac, and RTCM104 drivers (if only because they
+don't configure any device settings).
+
+The SiRF driver now restores NMEA when necessary.  It also restores
+some (but not all) of the things it tweaks in binary mode -- at the
+moment, just the Navigation Parameters from message 0x13.  With more
+work, we should be able to do a full revert.
+
+The TSIP driver changes its per-cycle sentence inventory and thus 
+needs some state-restore logic.  This can be done; the same packet 0x35
+we use to configure it can be sent in a no-argument mode to query
+the current sentence mix for later restore.
+
+The FV18 changes its per-cycle sentence inventory to include GSAs. It
+is possible to query that inventory, though we don't have code to do
+it yet.
+
+Garmin devices are a mess.  We reconfigure those heavily, and we
+don't know if there's any way to capture their configuration state
+before we do it.
+
+The iTrax02 driver sets SYNCMODE to start navigation messages without
+checking to see if it's already on, and stops navigation methods on
+wrapup.  It also forces the set of sentences issued.  There doesn't
+seem to be any way to query these settings.
+
+*** Industry-standard format dumping of raw satellite data
+
+It would be useful to be able to extract RINEX (or some other standard)
+format data from any GPS device that can report pseudoranges etc.  This
+belongs in the daemon because the device drivers are already doing the
+packet-cracking needed to get the data off the chips.
+
+Several commodity chipsets (ANTARIS, iTrax3, SiRF and Trimble) readily
+output enough data to make this a chore, rather than a hard problem.
+
+It has been suggested one way to do this is to have a generic structure
+in memory and corresponding output message with clock, doppler carrier
+phase and pseudoranges. This message is then reformatted by a client
+program. There are numerous formats for this information, and it would
+be easier to adapt to new formats if the formatting and use was handled
+by something other than the gpsd daemon. Currently the RT-IGS format is
+looking like the favorite for implementation; it's a fairly lightweight
+protocol, flexible enough to handle all the quantities required, and it
+is actually in use in production reference networks. RT-IGS is also a
+packet-oriented format, rather than a file-oriented format like RINEX.
+
+*** RTCM3 support.
+
+Previous plans for more RTCM2 support seem to have been overtaken by
+events, e.g. the world moving to RTCM3. We have support for analyzing
+RTCM3 messages, but it's entirely theoretical - written from the
+standard.  We need to find a pair of files consisting of a
+representative set of RTCM3 sentences and some sort of ASCII dump of
+them so we can test whether our analyzer gets all the bitfield
+boundaries right.
+
+** Future features (?)
+
+*** Support for more survey / professional / up-scale receivers.
+
+Devices such as the Javad JNSCore, Hemisphere Crescent, Septentrio
+AsteRx and PolaRx, NovAtel Superstar2 and OEMV, Thales (Magellan
+Professional) AC12 and DG14 would all be welcome. Of course, these
+are not $50 usb mice...
+
+*** Audio cues in the client when the fix status changes
+
+Calum writes:
+>Is it possible to add functionality (with a switch to enable it to
+>avoid annoying those that don't want it) so that beeps indicate NO
+>FIX, FIX, and OFFLINE status changes?

+
+*** Set the system time zone from latitude/longitude
+
+If we're going to give gpsd the capability to set system time via
+ntpd, why not let it set timezone as well?  A good thing for hackers
+travelling with laptops!
+
+The major issue here is that I have not yet found code, or a
+database, that would allow mapping from lon/lat to timezone.
+And the rules change from year to year.
+
+Actually this should be built as a specialized client, as some
+people won't want it.
+
+From <http://www.linuxsa.org.au/tips/time.html>:
+
+    The timezone under Linux is set by a symbolic link from
+    /etc/localtime[1] to a file in the /usr/share/zoneinfo[2] directory
+    that corresponds with what timezone you are in. For example, since I'm
+    in South Australia, /etc/localtime is a symlink to
+    /usr/share/zoneinfo/Australia/South. To set this link, type:
+
+    ln -sf ../usr/share/zoneinfo/your/zone /etc/localtime
+
+    Replace your/zone with something like Australia/NSW or
+    Australia/Perth. Have a look in the directories under
+    /usr/share/zoneinfo to see what timezones are available.
+
+    [1] This assumes that /usr/share/zoneinfo is linked to /etc/localtime as it is under Red Hat Linux.
+
+    [2] On older systems, you'll find that /usr/lib/zoneinfo is used
+    instead of /usr/share/zoneinfo.
+
+Changing the hardlink will, of course, update the system timezone for
+all users.  If I were designing this feature, I'd ensure that the
+system timezone can be overridden by a user-set TZ, but I don't know
+if it actually works that way.
+
+If I'm reading the tea leaves correctly, this functionality is actually
+embedded in the GCC library version of tzset(), so the same method will
+work on any system that uses that.
+
+Problem: system daemons use the timezone set when they start up. You
+can't get them to grok a new one short of rebooting.

+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+
+   Special processing is performed if fewer than 24 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a quantity.  When fewer than 24 input
+   bits are available in an input group, zero bits are added (on the
+   right) to form an integral number of 6-bit groups.  Padding at the
+   end of the data is performed using the '=' character.
+
+   Since all base64 input is an integral number of octets, only the
+         -------------------------------------------------                       
+   following cases can arise:
+   
+       (1) the final quantum of encoding input is an integral
+           multiple of 24 bits; here, the final unit of encoded
+	   output will be an integral multiple of 4 characters
+	   with no "=" padding,
+       (2) the final quantum of encoding input is exactly 8 bits;
+           here, the final unit of encoded output will be two
+	   characters followed by two "=" padding characters, or
+       (3) the final quantum of encoding input is exactly 16 bits;
+           here, the final unit of encoded output will be three
+	   characters followed by one "=" padding character.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+

+ * 1) It detects all single bit errors per 24-bit code word.
+ * 2) It detects all double bit error combinations in a code word.
+ * 3) It detects any odd number of errors.
+ * 4) It detects any burst error for which the length of the burst is less than

+Description: GPS (Global Positioning System) daemon
+ gpsd is a service daemon that monitors one or more GPSes attached to a host
+ computer through serial or USB ports, making all data on the location/course/
+ velocity of the sensors available to be queried on TCP port 2947 of the host
+ computer.
+ .
+ With gpsd, multiple GPS client applications can share access to GPSes without
+ contention or loss of data. Also, gpsd responds to queries with a format that
+ is substantially easier to parse than the NMEA 0183 emitted by most GPSes.

+     several applications.

+/*
+ *
+ * This is the gpsd driver for EverMore GPSes operating in binary mode.
+ * About the only thing this gives us that NMEA won't is TDOP.
+ * But we'll get atomic position reports from it, which is good.
+ *
+ * The vendor site is <http://www.emt.com.tw>.
+ *
+ * This driver was written by Petr Slansky based on a framework by Eric S.
+ * Raymond.  The following remarks are by Petr Slansky.
+ *
+ * Snooping on the serial the communication between a Windows program and
+ * an Evermore chipset reveals some messages not described in the vendor
+ * documentation (Issue C of Aug 2002):
+ *
+ * 10 02 06 84 00 00 00 84 10 03	switch to binary mode (84 00 00 00)
+ * 10 02 06 84 01 00 00 85 10 03	switch to NMEA mode (84 01 00 00)
+ *
+ * 10 02 06 89 01 00 00 8a 10 03        set baud rate 4800
+ * 10 02 06 89 01 01 00 8b 10 03        set baud rate 9600
+ * 10 02 06 89 01 02 00 8c 10 03        set baud rate 19200
+ * 10 02 06 89 01 03 00 8d 10 03        set baud rate 38400
+ *
+ * 10 02 06 8D 00 01 00 8E 10 03        switch to datum ID 001 (WGS-84)
+ * 10 02 06 8D 00 D8 00 65 10 03        switch to datum ID 217 (WGS-72)
+ *
+ * These don't entail a reset of GPS as the 0x80 message does.
+ *
+ * 10 02 04 38 85 bd 10 03     answer from GPS to 0x85 message; ACK message
+ * 10 02 04 38 8d c5 10 03     answer from GPS to 0x8d message; ACK message
+ * 10 02 04 38 8e c6 10 03     answer from GPS to 0x8e message; ACK message
+ * 10 02 04 38 8f c7 10 03     answer from GPS to 0x8f message; ACK message
+ *
+ * The chip sometimes sends vendor extension messages with the prefix
+ * $PEMT,100. After restart, it sends a $PEMT,100 message describing the
+ * chip's configuration. Here is a sample:
+ *
+ * $PEMT,100,05.42g,100303,180,05,1,20,15,08,0,0,2,1*5A
+ * 100 - message type
+ * 05.42g - firmware version
+ * 100303 - date of firmware release DDMMYY
+ * 180 -  datum ID; 001 is WGS-84
+ * 05 - default elevation mask; see message 0x86
+ * 1 - default DOP select (1 is auto DOP mask); see message 0x87
+ * 20 - default GDOP; see message 0x87
+ * 15 - default PDOP
+ * 08 - default HDOP
+ * 0 - Normal mode, without 1PPS
+ * 0 - default position pinning control (0 disable, 1 enable)
+ * 2 - altitude hold mode (0 disable, 1 always, 2 auto)
+ * 1 - 2/1 satellite nav mode (0,1,2,3,4)
+ *          0 disable 2/1 sat nav mode
+ *          1 hold direction (2 sat)
+ *          2 clock hold only (2 sat)
+ *          3 direction hold then clock hold (1 sat)
+ *          4 clock hold then direction hold (1 sat)
+ *
+ * Message $PEMT,100 could be forced with message 0x85 (restart):
+ * 10 02 12 85 00 00 00 00 00 01 01 00 00 00 00 00 00 00 00 87 10 03
+ * 0x85 ID, Restart
+ * 0x00 restart mode (0 default, 1 hot, 2 warm, 3 cold, 4 test)
+ * 0x00 test start search PRN (1-32)
+ * 0x00 UTC second (0-59)
+ * 0x00 UTC Minute (0-59)
+ * 0x00 UTC Hour (0-23)
+ * 0x01 UTC Day (1-31)
+ * 0x01 UTC Month (1-12)
+ * 0x0000 UTC year (1980+x, uint16)
+ * 0x0000 Latitude WGS-84 (+/-900, 1/10 degree, + for N, int16)
+ * 0x0000 Longtitude WGS-84 (+/-1800, 1/10 degree, + for E, int16)
+ * 0x0000 Altitude WGS-84 (-1000..+18000, meters, int16)
+ * 0x87 CRC
+ *
+ * With message 0x8e it is possible to define how often each NMEA
+ * message is sent (0-255 seconds). It is possible with message 0x8e
+ * to activate PEMT,101 messages that have information about time,
+ * position, velocity and HDOP.
+ *
+ * $PEMT,101,1,02,00.0,300906190446,5002.5062,N,01427.6166,E,00259,000,0000*27
+ * $PEMT,101,2,06,02.1,300906185730,5002.7546,N,01426.9524,E,00323,020,0011*26
+ * 101 - message type, Compact Navigation Solution
+ * 2 - position status (1,2,3,4,5,6)
+ *      (1 invalid, 2 2D fix, 3 3D fix, 4 2D with DIFF, 5 3D with DIFF,
+ *       6 2/1 sat degrade mode)
+ * 06 - number of used satelites
+ * 02.1 - DOP (00.0 no fix, HDOP 2D fix, PDOP 3D fix)
+ * 300906185730 - date and time, UTC ddmmyyHHMMSS (30/09/2006 18:57:30)
+ * 5002.7546,N - Latitude (degree)
+ * 01426.9524,E - Longitude (degree)
+ * 00323 - Altitude (323 metres)
+ * 020 - heading (20 degrees from true north)
+ * 0011 - speed over ground (11 metres per second); documentation says km per h
+ *
+ * This is an exampe of an 0x8e message that activates all NMEA sentences
+ * with 1s period:
+ * 10 02 12 8E 7F 01 01 01 01 01 01 01 01 00 00 00 00 00 00 15 10 03
+ *
+ * There is a way to probe for this chipset. When binary message 0x81 is sent:
+ * 10 02 04 81 13 94 10 03
+ *
+ * EverMore will reply with message like this:
+ * *10 *02 *0D *20 E1 00 00 *00 0A 00 1E 00 32 00 5B *10 *03
+ * bytes marked with * are fixed
+ * Message in reply is information about logging configuration of GPS
+ *
+ * Another way to detect the EverMore chipset is to send one of the messages
+ * 0x85, 0x8d, 0x8e or 0x8f and check for a reply.
+ * The reply message from an EverMore GPS will look like this:
+ * *10 *02 *04 *38 8d c5 *10 *03
+ * 8d indicates that message 0x8d was sent;
+ * c5 is EverMore checksum, other bytes are fixed

+ * This file contains two drivers for Garmin receivers and some code
+ * shared by both drivers.
+ *
+ * One driver "garmin_usb_binary" handles the Garmin binary packet
+ * format supported by the USB Garmins tested with the Garmin 18 and
+ * other models.  (There is also "garmin_usb_binary_old".)  These are ONLY
+ * for USB devices reporting as: 091e:0003.
+ *
+ * The other driver "garmin_ser_binary" is for Garmin receivers via a
+ * serial port, whether or not one uses a USB/serial adaptor or a real
+ * serial port.  These receivers provide adequate NMEA support, so it
+ * often makes sense to just put them into NMEA mode.
+ *
+ * On Linux, USB Garmins (091e:0003) need the Linux garmin_gps driver and
+ * will not function without it.  On other operating systems, it is clear
+ * garmin_usb_binary_old does not work since it requires the Linux
+ * garmin_gps module.
+ *
+ * This code has been tested and at least at one time is known to work on
+ * big- and little-endian CPUs and 32 and 64 bit cpu modes.
+ *
+ *
+ * Documentation for the Garmin protocols can be found via
+ *   http://www.garmin.com/support/commProtocol.html
+ * The file IOSDK.zip contains IntfSpec.pdf, which describes the
+ * protocol in terms of Application, Link, and Physical.  This
+ * identical file is also available at:
+ *   http://www.garmin.com/support/pdf/iop_spec.pdf
+ * An older version of iop_spec.pdf that describes only Serial Binary
+ * is available at:
+ *   http://vancouver-webpages.com/pub/peter/iop_spec.pdf
+ * Information about the GPS 18
+ *   http://www.garmin.com/manuals/425_TechnicalSpecification.pdf
+ *
+ * There is one physical link protocol for serial which uses DLE/ETX
+ * framing.  There is another physical protocol for USB which relies
+ * on the packetization intrinstic to USB bulk pipes.
+ *
+ * There are several link protocols; all devices implement L000.
+ * There are then product-specific protocols; most devices implement
+ * L001.  Link protocols are the same and carried over either Physical
+ * protocol.
+ *
+ * Application protocols are named A000 and then with different
+ * 3-digit numbres.  They are carried over Link protocols.
+ *
+ * Thus, much of the higher-level code dealing the data formats is
+ * shared between USB Binary and Serial Binary.
+ *
+ * This code is partly from the Garmin IOSDK and partly from the
+ * sample code in the Linux garmin_gps driver.
+ *
+ * bad code by: Gary E. Miller <gem@rellim.com>

+ * -D 4 = packet details
+ * -D 5 = more packet details

+ *      hdop
+ *      vdop
+ *	magnetic variation
+ *

+Any or all of the data in the text sentence (except for the sentence start
+and sentence end fields) may be replaced with underscores to indicate
+invalid data.

+ * Driver for Navcom receivers using propietary NCT messages, a binary protocol.
+ *
+ * Vendor website: http://www.navcomtech.com/
+ * Technical references: http://www.navcomtech.com/support/docs.cfm
+ *
+ * Tested with two SF-2040G models
+ *
+ * At this stage, this driver implements the following commands:
+ *
+ * 0x20: Data Request (tell the unit which responses you want)
+ * 0x3f: LED Configuration (controls the front panel LEDs -- for testing)
+ * 0x1c: Test Support Block (again, blinks the front panel lights)
+ *
+ * and it understands the following responses:
+ *
+ * 0x06: Acknowledgement (without error)
+ * 0x15: Negative Acknowledge
+ * 0x86: Channel Status
+ * 0xae: Identification Block
+ * 0xb0: Raw Meas. Data Block
+ * 0xb1: PVT Block
+ * 0xb5: Pseudorange Noise Statistics
+ * 0xd3: LBM DSP Status Block
+ * 0xef: Clock Drift and Offset
+ *

+ * A prototype driver.  Doesn't run, doesn't even compile.
+ *
+ * For new driver authors: replace "_PROTO_" and "_proto_" with the name of
+ * your new driver. That will give you a skeleton with all the required
+ * functions defined.
+ *
+ * Once that is done, you will likely have to define a large number of
+ * flags and masks. From there, you will be able to start extracting
+ * useful quantities. There are roughed-in decoders for the navigation
+ * solution, satellite status and gps-utc offset. These are the 3 key
+ * messages that gpsd needs. Some protocols transmit error estimates
+ * separately from the navigation solution; if developing a driver for
+ * such a protocol you will need to add a decoder function for that
+ * message.
+ *
+ * For anyone hacking this driver skeleton: "_PROTO_" and "_proto_" are now
+ * reserved tokens. We suggest that they only ever be used as prefixes,
+ * but if they are used infix, they must be used in a way that allows a
+ * driver author to find-and-replace to create a unique namespace for
+ * driver functions.
+ *
+ * If using vi, ":%s/_PROTO_/MYDRIVER/g" and ":%s/_proto_/mydriver/g"
+ * should produce a source file that comes very close to being useful.
+ * You will also need to add hooks for your new driver to:
+ * Makefile.am
+ * drivers.c
+ * gpsd.h-tail
+ * libgpsd_core.c
+ * packet.c
+ * packet_states.h

+/*****************************************************************************
+
+This is a decoder for RTCM-104 2.x, an obscure and complicated serial
+protocol used for broadcasting pseudorange corrections from
+differential-GPS reference stations.  The applicable
+standard is
+
+RTCM RECOMMENDED STANDARDS FOR DIFFERENTIAL NAVSTAR GPS SERVICE,
+RTCM PAPER 194-93/SC 104-STD
+
+Ordering instructions are accessible from <http://www.rtcm.org/>
+under "Publications".  This describes version 2.1 of the RTCM specification.
+RTCM-104 was later incrementally revised up to a 2.3 level before being 
+completely redesigned as level 3.0.
+
+Also applicable is ITU-R M.823: "Technical characteristics of
+differential transmissions for global navigation satellite systems
+from maritime radio beacons in the frequency band 283.5 - 315 kHz in
+region 1 and 285 - 325 kHz in regions 2 & 3."
+
+The RTCM 2.x protocol uses as a transport layer the GPS satellite downlink
+protocol described in IS-GPS-200, the Navstar GPS Interface
+Specification.  This code relies on the lower-level packet-assembly
+code for that protocol in isgps.c.
+
+The lower layer's job is done when it has assembled a message of up to
+33 words of clean parity-checked data.  At this point this upper layer
+takes over.  struct rtcm2_msg_t is overlaid on the buffer and the bitfields
+are used to extract pieces of it.  Those pieces are copied and (where
+necessary) reassembled into a struct rtcm2_t.
+
+This code and the contents of isgps.c are evolved from code by Wolfgang
+Rupprecht.  Wolfgang's decoder was loosely based on one written by
+John Sager in 1999 (in particular the dump function emits a close
+descendant of Sager's dump format).  Here are John Sager's original
+notes:
+
+The RTCM decoder prints a legible representation of the input data.
+The RTCM SC-104 specification is copyrighted, so I cannot
+quote it - in fact, I have never read it! Most of the information
+used to develop the decoder came from publication ITU-R M.823.
+This is a specification of the data transmitted from LF DGPS
+beacons in the 300kHz band. M.823 contains most of those parts of
+RTCM SC-104 directly relevant to the air interface (there
+are one or two annoying and vital omissions!). Information
+about the serial interface format was gleaned from studying
+the output of a beacon receiver test program made available on
+Starlink's website.

+/*****************************************************************************
+
+This is a decoder for RTCM-104 2.x, an obscure and complicated serial
+protocol used for broadcasting pseudorange corrections from
+differential-GPS reference stations.  The applicable
+standard is
+
+RTCM RECOMMENDED STANDARDS FOR DIFFERENTIAL NAVSTAR GPS SERVICE,
+RTCM PAPER 194-93/SC 104-STD
+
+Ordering instructions are accessible from <http://www.rtcm.org/>
+under "Publications".  This describes version 2.1 of the RTCM specification.
+RTCM-104 was later incrementally revised up to a 2.3 level before being 
+completely redesigned as level 3.0.
+
+Also applicable is ITU-R M.823: "Technical characteristics of
+differential transmissions for global navigation satellite systems
+from maritime radio beacons in the frequency band 283.5 - 315 kHz in
+region 1 and 285 - 325 kHz in regions 2 & 3."
+
+The RTCM 2.x protocol uses as a transport layer the GPS satellite
+downlink protocol described in IS-GPS-200, the Navstar GPS Interface
+Specification.  This code relies on the lower-level packet-assembly
+code for that protocol in isgps.c.
+
+The lower layer's job is done when it has assembled a message of up to
+33 words of clean parity-checked data.  At this point this upper layer
+takes over.  struct rtcm2_msg_t is overlaid on the buffer and the bitfields
+are used to extract pieces of it.  Those pieces are copied and (where
+necessary) reassembled into a struct rtcm2_t.
+
+This code and the contents of isgps.c are evolved from code by Wolfgang
+Rupprecht.  Wolfgang's decoder was loosely based on one written by
+John Sager in 1999 (in particular the dump function emits a close
+descendant of Sager's dump format).  Here are John Sager's original
+notes:
+
+The RTCM decoder prints a legible representation of the input data.
+The RTCM SC-104 specification is copyrighted, so I cannot
+quote it - in fact, I have never read it! Most of the information
+used to develop the decoder came from publication ITU-R M.823.
+This is a specification of the data transmitted from LF DGPS
+beacons in the 300kHz band. M.823 contains most of those parts of
+RTCM SC-104 directly relevant to the air interface (there
+are one or two annoying and vital omissions!). Information
+about the serial interface format was gleaned from studying
+the output of a beacon receiver test program made available on
+Starlink's website.

+/*****************************************************************************
+
+This is a decoder for RTCM-104 3.x, a serial protocol used for
+broadcasting pseudorange corrections from differential-GPS reference
+stations.  The applicable specification is RTCM 10403.1: RTCM Paper
+177-2006-SC104-STD.  This obsolesces the esrlier RTCM-104 2.x
+specifications. The specification document is proprietary; ordering 
+instructions are accessible from <http://www.rtcm.org/>
+under "Publications".  
+
+Unike the RTCM 2.x protocol, RTCM3.x does not use the strange
+sliding-bit-window IS-GPS-200 protocol as a transport layer, but is a
+self-contained byte-oriented packet protocol.  Packet recognition is
+handled in the GPSD packet-getter state machine; this code is
+concerned with unpacking the packets into well-behaved C structures,
+coping with odd field lengths and fields that may overlap byte
+boudaries.  These report structures live in gps.h.
+
+Note that the unpacking this module does is probably useful only for
+RTCM reporting and diagnostic tools.  It is not necessary when
+passing RTCM corrections to a GPS, which normally should just be
+passed an entire correction packet for processing by their internal
+firmware.

+ * This is the gpsd driver for SiRF GPSes operating in binary mode.
+ * It also handles uBlox, a SiRF derivative.
+ *
+ * The advantage: Reports climb/sink rate (raw-mode clients won't see this).
+ * The disadvantages: Doesn't return PDOP or VDOP, just HDOP.
+ *
+ * Chris Kuethe, our SiRF expert, tells us:
+ *
+ * "I don't see any indication in any of my material that PDOP, GDOP
+ * or VDOP are output. There are quantities called Estimated
+ * {Horizontal Position, Vertical Position, Time, Horizonal Velocity}
+ * Error, but those are apparently only valid when SiRFDRive is
+ * active."
+ *
+ * "(SiRFdrive is their Dead Reckoning augmented firmware. It
+ * allows you to feed odometer ticks, gyro and possibly
+ * accelerometer inputs to the chip to allow it to continue
+ * to navigate in the absence of satellite information, and
+ * to improve fixes when you do have satellites.)"
+ *
+ * "[When we need RINEX data, we can get it from] SiRF Message #5.
+ *  If it's no longer implemented on your receiver, messages
+ * 7, 28, 29 and 30 will give you the same information."

+/***************************************************************************
+ We've stopped interpreting GND (0x29) for the following reasons:
+
+1) Versions of SiRF firmware still in wide circulation (and likely to be
+   so for a while) don't report a valid time field, leading to annoying
+   twice-per-second jitter in client displays.
+
+2) What we wanted out of this that MND didn't give us was horizontal and
+   vertical error estimates. But we have to do our own error estimation by
+   computing DOPs from the skyview covariance matrix anyway, because we
+   want separate epx and epy errors a la NMEA 3.0.
+
+3) The fix-merge logic in gpsd.c is (unavoidably) NMEA-centric and
+   thinks multiple sentences in one cycle should be treated as
+   incremental updates.  This leads to various silly results when (as
+   in GND) a subsequent sentence is (a) intended to be a complete fix
+   in itself, and (b) frequently broken.
+
+4) Ignoring this dodgy sentence allows us to go to a nice clean single
+   fix update per cycle.
+
+Code left in place in case we need to reverse this decision.

+	 * 450 ms after the second.  And if some other task jumps up

+	 * ms after the second.  Things can get out of sync to the
+	 * point that if you try to resolve the GPS time of our 1 PPS
+	 * pulses using the navigation messages, you will find it

+ * The structure describing an uncertainty volume in kinematic space.
+ * This is what GPSes are meant to produce; all the other info is 
+ * technical impedimenta.
+ *
+ * All double values use NAN to indicate data not available.
+ *
+ * Usually all the information in this structure was considered valid
+ * by the GPS at the time of update.  This will be so if you are using
+ * a GPS chipset that speaks SiRF binary, Garmin binary, or Zodiac binary.
+ * This covers over 80% of GPS products in early 2005.
+ *
+ * If you are using a chipset that speaks NMEA, this structure is updated
+ * in bits by GPRMC (lat/lon, track, speed), GPGGA (alt, climb), GPGLL 
+ * (lat/lon), and GPGSA (eph, epv).  Most NMEA GPSes take a single fix
+ * at the beginning of a 1-second cycle and report the same timestamp in
+ * GPRMC, GPGGA, and GPGLL; for these, all info is guaranteed correctly
+ * synced to the time member, but you'll get different stages of the same 
+ * update depending on where in the cycle you poll.  A very few GPSes, 
+ * like the Garmin 48, take a new fix before more than one of of 
+ * GPRMC/GPGGA/GPGLL during a single cycle; thus, they may have different 
+ * timestamps and some data in this structure can be up to 1 cycle (usually
+ * 1 second) older than the fix time.
+ *
+ * Error estimates are at 95% confidence.

+
+<para>These are the demonstration clients shipped with
+<application>gpsd</application>. They have some common options:</para> 
+
+<para>The <option>-h</option> option causes each client to emit a summary of its
+options and then exit.</para>
+
+<para>The <option>-V</option> option causes each client to dump the package
+version and exit.</para>
+
+<para> The <option>-l</option> option, when present, sets the format
+of latitude and longitude reports.  The value 'd' produces decimal
+degrees and is the default.  The value 'm' produces degrees and
+decimal minutes.  The value 's' produces degrees, minutes, and decimal
+seconds.</para>
+
+<para><application>xgps</application>,
+<application>cgps</application>, and <application>ldcgps</application>
+look at variables in the environment to figure out what units they
+should default to using for display &mdash; imperial, nautical, or
+metric.  Here are the variables and values they check:</para>
+
+<screen>
+    GPSD_UNITS one of: 
+              imperial   = miles/feet
+              nautical   = knots/feet
+              metric     = km/meters
+    LC_MEASUREMENT
+	      en_US      = miles/feet
+              C          = miles/feet
+              POSIX      = miles/feet
+              [other]    = km/meters
+    LANG
+	      en_US      = miles/feet
+              C          = miles/feet
+              POSIX      = miles/feet
+              [other]    = km/meters
+</screen>
+<para>These preferences may be overridden by the <option>-u</option>
+option.</para>
+
+<para>Where present, the <option>-u</option> option can be used to set
+the system units for display; follow the keyword with 'i' for
+'imperial' for American units (feet in altitude and error estimates,
+miles per hour in speeds), 'n' for 'nautical' (feet in altitude and
+error estimates, knots in speed) or 'm' for 'metric' (meters in
+altitude and error estimates, kiliometers per hour in speeds). </para>
+
+<para> The <option>-D</option> option, when present, sets a debug
+level; it is primarily for use by GPSD developers.  It enables
+various progress messages to standard error.</para>
+
+<para>By default, clients collect data from all compatible devices on
+localhost, using the defalt GPSD port 2947. An optional argument to any
+client may specify a server to get data from. A colon-separated suffix
+is taken as a port number. If there is a second colon-separated
+suffix, that is taken as a specific device name to be
+watched. However, if the server specification contains square
+brackets, the part inside them is taken as an IPv6 address and
+port/device suffixes are obnly parsed after the trailing bracket.
+Possible cases look like this:</para>
+
+<variablelist>
+<varlistentry>
+<term>localhost:/dev/ttyS1</term>
+<listitem><para>Look at the default port of localhost, trying both

+and
+<citerefentry><refentrytitle>gpsmon</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
+
+<refsect2><title>xgps</title>
+
+<para><application>xgps</application> is a simple test client for
+<application>gpsd</application> with an X interface. It displays
+current GPS position/time/velocity information and (for GPSes that
+support the feature) the locations of accessible satellites.</para>
+
+<para>In the sky view, satellites are color-coded to indicate quality
+of signal; consult the data display to the left for exact figures in
+dB. Square icons indicate WAAS/EGNOS satellites, circles indicate
+ordinary GPS satellites.  Filled icons were used in the last fix, 
+outline icons were not.</para>
+
+</refsect2>
+<refsect2><title>xgpsspeed</title>
+
+<para><application>xgpsspeed</application> is a speedometer that uses
+position information from the GPS. It accepts an -h option and
+optional argument as for <application>gps</application>, or a -V
+option to dump the package version and exit.</para>
+
+<para>The -speedunits option can be used to set the speed units for
+display; follow the keyword with knots for nautical miles per hour,
+kph for kilometres per hour, or mph for miles per hour.  The default
+is miles per hour. </para>
+
+</refsect2>
+<refsect2><title>cgps</title>
+
+<para><application>cgps</application> is a client resembling 
+<application>xgps</application>, but without the pictorial 
+satellite display and able to run on a serial terminal or
+terminal emulator.</para>
+
+<para> The <option>-s</option> option prevents <application>cgps</application>
+from displaying the raw data. This display can also be toggled with the s
+command.</para>
+
+<para>The <option>-m</option> option will display your magnetic
+heading (as opposed to your true heading).  This is a calculated
+value, not a measured value, and is subject to a potential error of up
+to two degrees in the areas for which the calculation is valid
+(currently Western Europe, Alaska, and Lower 48 in the USA).  The
+formulas used are those found in the Aviation Formulary v1.43.</para>
+
+<para><application>cgps</application> terminates when you send it a
+SIGHUP or SIGINT; given default terminal settings this will happen
+when you type Ctl-C at it.  It will also terminate on 'q'</para>
+
+</refsect2>
+<refsect2><title>lcdgps</title>
+
+<para>A client that passes <application>gpsd</application> data to
+<application>lcdproc</application>, turning your car computer into a
+very expensive and nearly feature-free GPS receiver.  Currently
+assumes a 4x40 LCD and writes data formatted to fit that size screen.
+Also displays 4- or 6-character Maidenhead grid square output.</para>
+
+</refsect2>
+<refsect2><title>gpxlogger</title>
+
+<para>This program collects fixes from <application>gpsd</application>
+and logs them to standard output in GPX, an XML profile for track 
+logging.</para>
+
+<para>The output may be composed of multiple tracks. A new track is
+created if there's no fix for an interval specified by the
+<option>-i</option> and defaulting to 5 seconds.</para>
+
+<para>If D-Bus support is available on the host and GPSD is
+configured  to use it, this program listens to DBUS broadcasts 
+from <application>gpsd</application>. (org.gpsd.fix).  Otherwise,
+it uses a conventional socket connection. </para>
+
+<para>Presence of a server-port-device specification forces use of
+sockets even on a D-Bus capable system, though this is unlikely to be
+of interest to anyone except GPSD developers.</para>

+gpsfake.py -- classes for creating a controlled test environment around gpsd.
+
+The gpsfake(1) regression tester shipped with gpsd is a trivial wrapper
+around this code.  For a more interesting usage example, see the
+valgrind-audit script shipped with the gpsd code.
+
+To use this code, start by instantiating a TestSession class.  Use the
+prefix argument if you want to run the daemon under some kind of run-time
+monitor like valgrind or gdb.  Here are some particularly useful possibilities:
+
+valgrind --tool=memcheck --gen-suppressions=yes --leak-check=yes
+    Run under Valgrind, checking for malloc errors and memory leaks.
+
+xterm -e gdb -tui --args
+    Run under gdb, controlled from a new xterm.
+
+You can use the options argument to pass in daemon options; normally you will
+use this to set the debug-logging level.
+
+On initialization, the test object spawns an instance of gpsd with no
+devices or clients attached, connected to a control socket.
+
+TestSession has methods to attach and detch fake GPSes. The
+TestSession class simulates GPS devices for you with objects composed
+from a pty and a class instance that cycles sentences into the master side
+from some specified logfile; gpsd reads the slave side.  A fake GPS is
+identified by the string naming its slave device.
+
+TestSession also has methods to start and end client sessions.  Daemon
+responses to a client are fed to a hook function which, by default,
+discards them.  You can change the hook to sys.stdout.write() to dump
+responses to standard output (this is what the gpsfake executable
+does) or do something more exotic. A client session is identified by a
+small integer that counts the number of client session starts.
+
+There are a couple of convenience methods.  TestSession.wait() does nothing,
+allowing a specified number of seconds to elapse.  TestSession.send()
+ships commands to an open client session.
+
+TestSession does not currently capture the daemon's log output.  It is
+run with -N, so the output will go to stderr (along with, for example,
+Valgrind notifications).
+
+Each FakeGPS instance tries to packetize the data from the logfile it
+is initialized with. It uses the same packet-getter as the daeomon.
+
+The TestSession code maintains a run queue of FakeGPS and gps.gs (client-
+session) objects. It repeatedly cycles through the run queue.  For each
+client session object in the queue, it tries to read data from gpsd.  For
+each fake GPS, it sends one line of stored data.  When a fake-GPS's
+go predicate becomes false, the fake GPS is removed from the run queue.
+
+There are two ways to use this code.  The more deterministic is
+non-threaded mode: set up your client sessions and fake GPS devices,
+then call the run() method.  The run() method will terminate when
+there are no more objects in the run queue.  Note, you must have
+created at least one fake client or fake GPS before calling run(),
+otherwise it will terminate immediately.
+
+To allow for adding and removing clients while the test is running,
+run in threaded mode by calling the start() method.  This simply calls
+the run method in a subthread, with locking of critical regions.

+# Further notes:
+# * In the packaging feld, a "GPS mouse" is a standalone sensor in a
+#   display-less case designed be used as an outbard peripheral.  An
+#   "OEM module" is an un-cased circuit board with edge connectors; a
+#   "chipset" is what it sounds like.
+#   A "handset" is a standalone GPS with a display and human-usable
+#   controls. A "handsfree" is a hands-free unit with display designed for 
+#   mounting on a car windshield or boat dash.
+# * In the rating field:
+#    "excellent" - gpsd recognizes the GPS rapidly and reliably,
+#		  reports are complete and correct.
+#    "good" -- gpsd has minor problems or lag recognizing the device,
+#	      but reports are complete and correct.
+#    "fair" -- Reports have minor dropouts or problems, including occasional
+#	      transient nonsense values.
+#    "poor" -- Reports frequently have values that are wrong or nonsense.
+#    "broken" -- gpsd frequently fails to recognize the device at all.

+      too much data is thrown at it (ie. gpsd probes) thus it may
+      require a read-only (-b) instance of gpsd. (We say 'may' because
+      more recent instances of gpsd break the probe writes into pieces
+      interleaved with read, and may no longer trigger this problem)

+
+<para><application>gpscat</application> is a simple program for
+logging and packetizing GPS data streams.  It takes input from a
+specified file or serial device (presumed to have a GPS attached) and
+reports to standard output. The program runs until end of input or it is
+interrupted by ^C or other means. It does not terminate on a bad
+backet; this is intentional.</para>
+
+<para>In raw mode (the default) <application>gpscat</application>
+simply dumps its input to standard output.  Nonprintable characters
+other than ASCII whitepace are rendered as hexadecimal string escapes.</para>
+
+<para>In packetizing mode, <application>gpscat</application> uses the
+same code as
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>8</manvolnum></citerefentry>'s
+packet sniffer to break the input into packets.  Packets are reported
+one per line; line breaks in the packets themselves are
+escaped.</para>
+
+<para>This program is useful as a sanity checker when examining a new
+device.  It can be used as a primitive NMEA logger, but beware that
+(a) interrupting it likely to cut off output in mid-sentence, and (b)
+to avoid displaying incomplete NMEA sentences right up next to shell
+prompts that often contain a $, raw mode always emits an extra final
+linefeed.</para>
+
+<para>Also, be aware that packetizing mode will produce useless
+results &mdash; probably consuming the entirety of input and appearing
+to hang &mdash; if it is fed data that is not a sequence of packets
+of one of the known types.</para>
+
+<para>The program accepts the following options:</para>

+<para>Set the port's baud rate (and optionally its parity and stop
+bits) before reading.  Argument should begin with one of the normal integer
+baud rates (300, 1200, 4800, 9600, 19200, 38400, etc.).  It may be
+followed by an optional suffix [NOE][12] to set parity (None, Even,
+Odd) and stop bits (1 or 2).</para>

+<para><application>gpsctl</application> can switch a dual-mode GPS
+between NMEA and vendor-binary modes.  It can also be used to set the
+device baudrate.  Note:  Not all devices have these capabilities.</para>
+
+<para>If you have only one GPS attached to your machine, and gpsd is
+running, it is not necessary to specify the device;
+<application>gpsctl</application> does its work through
+<application>gpsd</application>, which will locate it for you.</para>
+
+<para>When <application>gpsd</application> is not running, the device
+specification is required, and you will almost certainly need to be
+running as root in order to have write access to the device.</para>
+
+<para>The program accepts the following options:</para>

+also possible for serial mode setting to fail either because the
+serial adaptor chip does not support non-8N1 modes or because the
+device firmware does not properly synchronize the serrial adaptor chip
+with the UART on the GPS chipset whjen the speed changes. These

+must include the leading $ for NMEA packets.) When sending to a UBX
+device, the first two bytes of the string supplied will become the
+message class and type, and the remainder the payload. When sending to
+a Navcom NCT or Trimble TSIP device, the first byte is interpreted as
+the command ID and the rest as payload. When sending to a Zodiac
+device, the first two bytes are used as a message ID of type
+little-endian short, and the remainder as payload in byte pairs
+interpreted as little-endian short. C-style backslash escapes in the

+
+<para>Forcing the device type behaves somewhat differently depending 
+on whether this tool is going through the daemon or not. In high-level
+mode, if the device that daemon selects for you doesn't match the
+driver you specified, <application>gpsctl</application> exits with
+a warning.  (This may be useful in scripts.)</para>
+
+<para>In low-level mode, if the device identifies as a Generic NMEA,
+use the selected driver instead.  This will be useful if you have a
+GPS device of known type that is in NMEA mode and not responding to
+probes.  (This option was originally implemented for talking to
+SiRFStar I chips, which don't respond to the normal SiRF ID
+probe.)</para>

+ * power, they actually shut down the Bluetooth RF stage as well and
+ * only re-wake it periodically to see if an attempt to raise the
+ * device is in progress.  The result is that if you close the device
+ * when it's powered up, a re-open can fail with EIO and needs to be

+
+<para>On Linux systems supporting udev, <application>gpsd</application>
+is normally started automatically when a USB plugin event fires (if it

+<refsect1 id='description'><title>DESCRIPTION</title>
+
+<para><application>gpsd</application> is a monitor daemon that collects
+information from GPSes, differential-GPS radios, or AIS receivers
+attached to the host machine.  Each GPS, DGPS radio, or AIS receiver
+is expected to be direct-connected to the host via a USB or RS232C
+serial device.  The serial device may be specified to
+<application>gpsd</application> at startup, or it may be set via a
+command shipped down a local control socket (e.g. by a USB hotplug
+script). Given a GPS device by either means,
+<application>gpsd</application> discovers the correct port speed and
+protocol for it.</para>
+
+<para><application>gpsd</application> should be able to query any GPS
+that speaks either the standard textual NMEA 0183 protocol, or the
+(differing) extended NMEA dialects used by MKT-3301, iTrax, Motorola
+OnCore, Sony CXD2951, and Ashtech/Thales devices.  It can also
+interpret the binary protocols used by EverMore, Garmin, Navcom,
+Rockwell/Zodiac, SiRF, Trimble, and uBlox ANTARIS devices. It can read
+heading and attitude information from the Oceanserver 5000 orv TNT
+Revolution digital compasses.</para>
+
+<para>The GPS reporting formats supported by your instance of
+<application>gpsd</application> may differ depending on how it was
+compiled; general-purpose versions support many, but it can be built
+with protocol subsets down to a singleton for use in constrained
+environments. For a list of the GPS protocols supported by your
+instance, see the output of <command>gpsd -l</command></para>
+
+<para><application>gpsd</application> effectively hides the
+differences among the GPS types it supports. It also knows about and
+uses commands that tune these GPSes for lower latency. By using
+<application>gpsd</application> as an intermediary applications 
+avoid contention for serial devices.</para>
+
+<para><application>gpsd</application> can use differential-GPS
+corrections from a DGPS radio or over the net, from a ground station
+running a DGPSIP server or a Ntrip broadcaster that reports RTCM-104
+data; this will shrink position errors by roughly a factor of four.
+When <application>gpsd</application> opens a serial device emitting
+RTCM-104, it automatically recognizes this and uses the device as a
+correction source for all connected GPSes that accept RTCM corrections
+(this is dependent on the type of the GPS; not all GPSes have the
+firmware capability to accept RTCM correction packets). See 
+<xref linkend='accuracy'/> and <xref linkend='files'/> for discussion.</para>
+
+<para>Client applications will communicate with <application>gpsd</application>
+via a TCP/IP port, 2947 by default).  Both IPv4 and IPv6 connections
+are supported and a client may connect via either.</para>

+Normally, a data source is the device pathname of a local device from

+
+<variablelist>
+<varlistentry>
+<term>Local serial or USB device</term>
+<listitem>
+<para>A normal Unix device name of a serial or USB device to which a
+sensor is attached. Example:
+<filename>/dev/ttyUSB0</filename>.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>TCP feed</term>
+<listitem>
+<para>A URI with the prefix "tcp://", followed by a hostname, a
+colon, and a port number. The daemon will open a socket to the
+indicated address and port and read data packets from it, which will 
+be interpreted as though they had been issued by a serial device. Example:
+<filename>tcp://data.aishub.net:4006</filename>.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>UDP feed</term>
+<listitem>
+<para>A URI with the prefix "udp://", followed by a hostname, a
+colon, and a port number. The daemon will open a socket listening for
+UDP datagrams arriving on the indicated address and port, which will 
+be interpreted as though they had been issued by a serial device. Example:
+<filename>udp://127.0.0.1:5000</filename>.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>Ntrip caster</term>
+<listitem>
+<para>A URI with the prefix "ntrip://" followed by the name of an
+Ntrip caster (Ntrip is a protocol for broadcasting differential-GPS
+fixes over the net). For Ntrip services that require authentication, a
+prefix of the form "username:password@" can be added before the name
+of the Ntrip broadcaster.  For Ntrip service, you must specify which
+stream to use; the stream is given in the form "/streamname". An
+example DGPSIP URI could be "dgpsip://dgpsip.example.com" and a Ntrip
+URI could be
+"ntrip://foo:bar@ntrip.example.com:80/example-stream". Corrections
+from the caster will be send to each attached GPS with the capability
+to accept them.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>DGPSIP server</term>
+<listitem>
+<para>A URI with the prefix "dgpsip://" followed by a hostname, a
+colon, and an optional colon-separated port number (defaulting to
+2101). The daemon will handshake with the DGPSIP server and 
+read RTCM2 correction data from it. Corrections
+from the server will be set to each attached GPS with the capability
+to accept them.Example:
+<filename>dgpsip://dgps.wsrcc.com:2101</filename>.</para>
+</listitem>
+</varlistentry>
+</variablelist>
+
+<para>(The "ais:://" source type supported in some older versions of
+the daemon has been retired in favor of the more general
+"tcp://".)</para>
+
+<para>Internally, the daemon maintains a device pool holding the
+pathnames of devices and remote servers known to the
+daemon. Initially, this list is the list of device-name arguments
+specified on the command line.  That list may be empty, in which case
+the daemon will have no devices on its search list until they are
+added by a control-socket command (see <xref linkend='devices'/> for
+details on this).  Daemon startup will abort with an error if neither
+any devices nor a control socket are specified.</para>
+
+<para>Clients communicate with the daemon via textual request and
+responses. It is a bad idea for applications to speak the protocol
+directly: rather, they should use the
+<application>libgps</application> client library and take appropriate
+care to conditionalize their code on the major and minor protocol
+version symbols.</para>
+
+</refsect1>
+<refsect1 id='protocol'><title>REQUEST/RESPONSE PROTOCOL</title>
+
+<para>The GPSD protocol is built on top of JSON, JaveScript
+Object Notation. Use of this metaprotocol to pass structured
+data between daemon and client avoids the non-extensibility
+problems of the old protocol, and permits a richer set of record types
+to be passed up to clients.</para>
+
+<para>A request line is introduced by "?" and may include multiple
+commands.  Commands begin with a command identifier, followed either

+
+<para>gpsd can provide reference clock information to
+<application>ntpd</application>, to keep the system clock synchronized
+to the time provided by the GPS receiver.  This facility is
+only available when the daemon is started from root.  If you're going
+to use <application>gpsd</application> you probably want to run it
+<option>-n</option> mode so the clock will be updated even when no
+clients are active.</para>
+
+<para>Note that deriving time from messages received from the GPS is
+not as accurate as you might expect.  Messages are often delayed in
+the receiver and on the link by several hundred milliseconds, and this
+delay is not constant.  On Linux, <application>gpsd</application>
+includes support for interpreting the PPS pulses emitted at the start
+of every clock second on the carrier-detect lines of some serial
+GPSes; this pulse can be used to update NTP at much higher accuracy
+than message time provides.  You can determine whether your GPS emits
+this pulse by running at -D 5 and watching for carrier-detect state
+change messages in the logfile.</para>
+
+<para>When <application>gpsd</application> receives a sentence with a
+timestamp, it packages the received timestamp with current local time
+and sends it to a shared-memory segment with an ID known to
+<application>ntpd</application>, the network time synchronization
+daemon.  If <application>ntpd</application> has been properly
+configured to receive this message, it will be used to correct the
+system clock.</para>
+
+<para>Here is a sample <filename>ntp.conf</filename> configuration
+stanza telling <application>ntpd</application> how to read the GPS
+notfications:</para>
+
+<programlisting>
+server 127.127.28.0 minpoll 4 maxpoll 4
+fudge 127.127.28.0 time1 0.420 refid GPS
+
+server 127.127.28.1 minpoll 4 maxpoll 4 prefer
+fudge 127.127.28.1 refid GPS1
+</programlisting>
+
+<para>The magic pseudo-IP address 127.127.28.0 identifies unit 0 of
+the <application>ntpd</application> shared-memory driver; 127.127.28.1
+identifies unit 1.  Unit 0 is used for message-decoded time and unit 1
+for the (more accurate, when available) time derived from the PPS
+synchronization pulse.  Splitting these notifications allows
+<application>ntpd</application> to use its normal heuristics to weight
+them.</para>
+
+<para>With this configuration, <application>ntpd</application> will
+read the timestamp posted by <application>gpsd</application> every 16
+seconds and send it to unit 0.  The number after the parameter time1
+is an offset in seconds.  You can use it to adjust out some of the
+fixed delays in the system.  0.035 is a good starting value for the
+Garmin GPS-18/USB, 0.420 for the Garmin GPS-18/LVC.</para>
+
+<para>After restarting ntpd, a line similar to the one below should
+appear in the output of the command "ntpq -p" (after allowing a couple
+of minutes):</para>
+
+<screen>

+
+<para>If you are running PPS then it will look like this:</para>
+
+<screen>
+remote	   refid      st t when poll reach  delay    offset  jitter
+=========================================================================

+</screen>
+
+<para>When the value under "reach" remains zero, check that gpsd is
+running; and some application is connected to it or the '-n' option was
+used.  Make sure the receiver is locked on to at least one satellite,
+and the receiver is in SiRF binary, Garmin binary or NMEA/PPS mode.  Plain
+NMEA will also drive ntpd, but the accuracy as bad as one second.  When
+the SHM(0) line does not appear at all, check the system logs for error
+messages from ntpd.</para>
+
+<para>When no other reference clocks appear in the NTP configuration,
+the system clock will lock onto the GPS clock.  When you have previously
+used <application>ntpd</application>, and other reference clocks appear
+in your configuration, there may be a fixed offset between the GPS clock
+and other clocks.  The <application>gpsd</application> developers would
+like to receive information about the offsets observed by users for each
+type of receiver.  Please send us the output of the "ntpq -p" command
+and the make and type of receiver.</para>

+
+<para>On operating systems that support D-BUS,
+<application>gpsd</application> can be built to broadcast GPS fixes to
+D-BUS-aware applications.  As D-BUS is still at a pre-1.0 stage, we
+will not attempt to document this interface here.  Read the

+<refsect1 id='security'><title>SECURITY AND PERMISSIONS ISSUES</title>
+
+<para><application>gpsd</application>, if given the -G flag, will
+listen for connections from any reachable host, and then disclose the
+current position.  Before using the -G flag, consider whether you
+consider your computer's location to be sensitive data to be kept
+private or something that you wish to publish.</para>
+
+<para><application>gpsd</application> must start up as root in order
+to open the NTPD shared-memory segment, open its logfile, and create
+its local control socket.  Before doing any processing of GPS data, it
+tries to drop root privileges by setting its UID to "nobody" (or another
+userid as set by configure) and its group ID to the group of the initial
+GPS passed on the command line &mdash; or, if that device doesn't exist,
+to the group of <filename>/dev/ttyS0</filename>.</para>
+
+<para>Privilege-dropping is a hedge against the possibility that
+carefully crafted data, either presented from a client socket or from
+a subverted serial device posing as a GPS, could be used to induce
+misbehavior in the internals of <application>gpsd</application>.
+It ensures that any such compromises cannot be used for privilege
+elevation to root.</para>
+
+<para>The assumption behind <application>gpsd</application>'s
+particular behavior is that all the tty devices to which a GPS might
+be connected are owned by the same non-root group and allow group
+read/write, though the group may vary because of distribution-specific
+or local administrative practice.  If this assumption is false,
+<application>gpsd</application> may not be able to open GPS devices in
+order to read them (such failures will be logged).</para>
+
+<para>In order to fend off inadvertent denial-of-service attacks by
+port scanners (not to mention deliberate ones),
+<application>gpsd</application> will time out inactive client
+connections.  Before the client has issued a command that requests a
+channel assignment, a short timeout (60 seconds) applies.  There is no
+timeout for clients in watcher or raw modes; rather,
+<application>gpsd</application> drops these clients if they fail to
+read data long enough for the outbound socket write buffer to fill.
+Clients with an assigned device in polling mode are subject to a
+longer timeout (15 minutes).</para>
+

+<refsect1 id='limitations'><title>LIMITATIONS</title>
+
+<para>If multiple NMEA talkers are feeding RMC, GLL, and GGA sentences
+to the same serial device (possible with an RS422 adapter hooked up to
+some marine-navigation systems), a 'TPV' response may mix an altitude
+from one device's GGA with latitude/longitude from another's RMC/GLL
+after the second sentence has arrived.</para>
+
+<para><application>gpsd</application> may change control settings on
+your GPS (such as the emission frequency of various sentences or
+packets) and not restore the original settings on exit.  This is a
+result of inadequacies in NMEA and the vendor binary GPS protocols,
+which often do not give clients any way to query the values of control
+settings in order to be able to restore them later.</para>
+
+<para>If your GPS uses a SiRF chipset at firmware level 231, reported
+UTC time may be off by the difference between 13 seconds and whatever
+leap-second correction is currently applicable, from startup until
+complete subframe information is received (normally about six
+seconds).  Firmware levels 232 and up don't have this problem.  You
+may run <application>gpsd</application> at debug level 4 to see the
+chipset type and firmware revision level.</para>
+
+<para>When using SiRF chips, the VDOP/TDOP/GDOP figures and associated
+error estimates are computed by <application>gpsd</application> rather
+than reported by the chip.  The computation does not exactly match
+what SiRF chips do internally, which includes some satellite weighting
+using parameters <application>gpsd</application> cannot see.</para>
+
+<para>Autobauding on the Trimble GPSes can take as long as 5 seconds
+if the device speed is not matched to the GPS speed.</para>
+
+<para>If you are using an NMEA-only GPS (that is, not using SiRF or
+Garmin or Zodiac binary mode) and the GPS does not emit GPZDA at the
+start of its update cycle (which most consumer-grade NMEA GPSes do
+not) and it is after 2099, then the century part of the dates
+<application>gpsd</application> delivers will be wrong.</para>
+
+<para>Generation of position error estimates (eph, epv, epd, eps, epc)
+from the incomplete data handed back by GPS reporting protocols
+involves both a lot of mathematical black art and fragile
+device-dependent assumptions.  This code has been bug-prone in tbe

+
+<para>This tool is a decoder/encoder for various binary packet formats
+associated with GPS and differential-correction services.  It produces
+a text dump on standard output from binary on standard input, or
+binary packets on standard output from text on standard input, and
+aims to be 100% information-preserving in both directions.  As well as
+data, the decoder also prints decoder status messages to standard
+error as necessary.</para>
+
+<para>Two of the supported formats are RTCM 2 and 3, a pair of obscure
+and complicated serial protocol used for broadcasting pseudorange
+corrections from differential-GPS reference stations. You can use this
+mode of the tool with
+<citerefentry><refentrytitle>nc</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+to examine RTCM feeds from DGPSIP servers or Ntrip broadcasters. The
+decoder dump formats for RTCM2 are described in
+<citerefentry><refentrytitle>rtcm</refentrytitle><manvolnum>5</manvolnum></citerefentry>;
+these lines go to standard output.</para>
+
+<para>Another supported format is AIVDM.  This is the sentence format
+used by the marine Automatic Identification System.  This can be
+decoded, but not yet encoded.</para>
+
+</refsect1>
+<refsect1 id='options'><title>OPTIONS</title>
+
+<para>The <option>-d</option> option tells the program to decode
+packets presented on standard input to a text dump on standard
+output. This is the default behavior.</para>
+
+<para>RTCM2 will be dumped in one of the formats of
+<citerefentry><refentrytitle>rtcm-104</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+on standard output. </para>
+
+<para>The <option>-e</option> option option tells the program to
+encode a text dump in one of the formats of
+<citerefentry><refentrytitle>rtcm-104</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+to standard output. This option is a placeholder: support for RTCM2
+encoding from the Sager format has been removed</para>
+
+<para>The <option>-u</option> suppresses scaling of AIS data to float quantities
+and text expansion of numeric codes.  A dump with this option is
+lossless.</para>
+
+<para>The <option>-j</option> sets the dump format to JSON, with
+each each field preceded by a quoted label and colon and the
+entire dump line wrapped in curly braces.</para>
+
+<para>The <option>-c</option> sets the AIS dump format to separate
+fields with an ASCII pipe symbol.  Fields are dumped in the order they
+occur in the AIS packet. Numerics are not scaled. Strings are unpacked
+from six-bit to full ASCII</para>
+
+<para>The <option>-V</option> option directs the program to emit its
+version number, then exit.</para>
+
+<para>The <option>-D</option> option sets a debug verbosity level.  It is
+mainly of interest to developers.</para>
+
+</refsect1>
+<refsect1 id='json_ais'><title>AIS DUMP FORMATS</title> 
+
+<para>Without the <option>-j</option> option, dump lines are values of AIS
+payload fields, pipe-separated, in the order that they occur in the
+payload. Spans of fields expressing a date are emitted as an ISO8601
+timestamp (look for colons and the trailing Z indicating Zulu/UTC
+time), and the 19-bit group of TDMA status fields found at the end of
+message types 1-4 are are dumped as a single unsigned integer (in hex
+preceded by "0x"). Unused regional-authority fields are also dumped
+(in hex preceded by "0x"). Variable-length binary fields are dumped as
+an integer bit length, followed by a colon, followed by a hex
+dump.</para>
+
+<para>By default, certain scaling and conversion operations are
+performed for the output.  Latitudes and longitudes are scaled to
+decimal degrees rather than the native AIS unit of 1/10000th of a
+minute of arc.  Ship (but not air) speeds are scaled to knots rather
+than tenth-of-knot units.  Navigation status and positioning-system
+type are dumped as text strings rather than IAS numeric codes. Rate of
+turn may appear as "nan" if is unavailable, or as one of the strings
+"fastright" or "fastleft" if it is out of the IAS encoding range;
+otherwise it is quadratically mapped back to the turn sensor number in
+degrees per minute. Vessel draughts are converted to decimal meters
+rather than native AIS decimeters.</para>
+
+<para>With the <option>-j</option> option, the AIS dump format changes
+to JSON.  Data fields are handled as described above in scaled and
+unscaled modes, but are values attached to JSON attributes as
+described in <citetitle><ulink
+url="http://gpsd.berlios.de/AIVDM.html">AIVDM/AIVDO protocol
+decoding</ulink></citetitle>.</para>

+<refsect1 id='standard'><title>APPLICABLE STANDARDS</title>
+
+<para>The applicable standard for V2 is <citetitle>RTCM Recommended
+Standards for Differential NAVSTAR GPS Service</citetitle> RTCM Paper
+194-93/SC 104-STD.</para>
+
+<para>Note that <application>gpsdecode</application> presently
+recognizes only the 2.1 level of RTCM; the protocol was revised up to
+a version 2.3 including additional messages relating to GLONASS and
+real-time kinematics before being deprecated in favor of V3. It is
+now semi-obsolete.</para>
+
+<para>The applicable standard for V3 is <citetitle>RTCM Standard
+10403.1 for Differential GNSS Services - Version 3</citetitle> RTCM
+Paper 177-2006-SC104-STD.</para>
+
+<para>Ordering instructions for the RTCM standards are accessible from
+the website of the <ulink url='http://www.rtcm.org/'>Radio Technical
+Commission for Maritime Services</ulink> under "Publications".</para>
+
+<para>The applicable standard for AIVDM is <citetitle>ITU-R M.1371:
+ITU Recommendation on the Technical Characteristics for a Universal
+Shipborne Automatic Identification System (AIS) using Time Division
+Multiple Access in the Maritime Mobile Band</citetitle>, A more
+accessible description can be found at <citetitle><ulink

+<refsect1 id='bugs'><title>BUGS AND LIMITATIONS</title> 
+
+<para>AIDVM decoding of types 16-17, 22-23, and 25-26 is unverified.</para>
+
+<para>RTCM3 decoding is buggy and incomplete.</para>
+
+<para>RTCM2 represents floating-point quantities as an integer
+multiple of a fixed scale factor.  Editing an RTCM2 dump can produce
+numbers that are not an integer multiple of the scale factor for their
+field.  If you do this, the value actually packed into binary RTCM2
+will be rounded down to the nearest scale unit, and dumping will show
+slightly different numbers than those you entered.  This bug could be
+fixed by supporting the <option>-u</option> option to suppress
+scaling.</para>
+
+<para>The RTCM2 decoder logic is sufficiently convoluted to confuse some
+compiler optimizers, notably in GCC 3.x at -O2, into generating bad
+code.</para>
+
+<para>Older version of this utility used comma as a field separator with
+the <option>-c</option> option.  This was a mistake, as ship name and
+other string fields can contain commas.</para>

+<refsect1 id='description'><title>DESCRIPTION</title>
+
+<para><application>gpsfake</application> is a test harness for 
+<application>gpsd</application> and its clients.  It opens a pty
+(pseudo-TTY), launches a <application>gpsd</application> instance that
+thinks the slave side of the pty is its GPS device, and repeatedly
+feeds the contents of one or more test logfiles through the master side to the
+GPS. If there are multiple logfiles, sentences from them are
+interleaved in the order the fuiles are specified.</para>
+
+<para><application>gpsfake</application> does not require root
+privileges, and can be run concurrently with a production 
+<application>gpsd</application> instance without causing problems.</para>
+
+<para>The logfiles may be of NMEA, SiRF packets, TSIP packets, or
+Zodiac packets.  Leading lines beginning with # will be treated as
+comments and ignored.</para>
+
+<para>The <application>gpsd</application> instance is run in
+foreground.  The thread sending fake GPS data to the daemon 
+is run in background.</para>
+
+</refsect1>
+<refsect1 id='options'><title>OPTIONS</title>
+
+<para>With the -1 option, the logfile is interpreted once only rather
+than repeatedly.  This option is intended to facilitate regression
+testing.</para>
+
+<para>The -b option enables a twirling-baton progress indicator
+on standard error.  At termination, it reports elapsed time.</para>
+
+<para>The -c option sets the delay between sentences in
+seconds. Fractional values of seconds are legal.  The default is zero
+(no delay).</para>
+
+<para>The -l option makes the program dump a line or packet number
+just before each sentence is fed to the daemon. If the sentence is
+textual (e.g. NMEA), the text is dumped as well.  If not, the packet
+will be dumped in hexadecimal (except for RTCM packets, which aren't
+dumped at all).  This option is useful for checking that gpsfake is
+getting packet boundaries right.</para>
+
+<para>The -i option is for single-stepping through logfiles.  It dumps
+the line or packet number (and the sentence if the protocol is
+textual) followed by "? ".  Only when the user keys Enter is the line
+actually fed to <application>gpsd</application>.</para>
+
+<para>The -m option specifies a monitor program inside which the
+daemon should be run.  This option is intended to be used with
+<citerefentry><refentrytitle>valgrind</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
+<citerefentry><refentrytitle>gdb</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+and similar programs.</para>
+
+<para>The -g option uses the monitor facility to run the
+<application>gpsd</application> instance within gpsfake under control
+of gdb.</para>
+
+<para>The -o option specifies options to pass to the daemon.  The -n
+option passes -n to start the daemon reading the GPS without waiting
+for a client (equivalent to -o "-n").  The -D option passes a -D
+option to the daemon: thus -D 4 is shorthand for -o "-D 4".</para>
+
+<para>The -p ("pipe") option sets watcher mode and dumps the NMEA and GPSD
+notifications generated by the log to standard output. This is useful
+for regression-testing.</para>
+
+<para>The -r option specifies an initialization command to use in pipe mode.  
+The default is <command>?WATCH={"enable":true,"json":true}</command>.</para>
+
+<para>The -s option sets the baud rate for the slave tty.  The
+default is 4800.</para>
+
+<para>The -u option forces the test framework to use UDP rather than
+pty devices. This may be useful for testing from within chroot jails
+where access to pty devices is locked out.</para>
+
+<para>The -v option enables verbose progress reports to stderr.  It is
+mainly useful for debugging <application>gpsfake</application>
+itself.</para>
+
+<para>The -x option dumps packets as
+<application>gpsfake</application> gathers them.  It is mainly useful
+for debugging <application>gpsfake</application> itself.</para>
+
+<para>The -h option makes <application>gpsfake</application> print 
+a usage message and exit.</para>
+
+<para>The argument must be the name of a file containing the 
+data to be cycled at the device. <application>gpsfake</application> 
+will print a notification each time it cycles.</para>
+
+<para>Normally, gpsfake creates a pty for each logfile and passes the
+slave side of the debice to the daemon.  If the header comment in the
+logfile contains the string "UDP", packets are instead shipped via UDP
+port 5000 to the addess 192.168.0.1.255.  You can monitoer them with
+this: <command>tcpdump -s0 -n -A -i lo udp and port 5000</command>.</para>

+
+<para><application>gpsfake</application> is a trivial wrapper around a
+Python module, also named gpsfake, that can be used to fully script
+sessions involving a <application>gpsd</application> instance, any
+number of client sessions, and any number of fake GPSes feeding the
+daemon instance with data from specified sentence logs.</para>
+
+<para>Source and embedded documentation for this module is shipped with the 
+<application>gpsd</application> development tools.  You can use it to
+torture-test either <application>gpsd</application> itself or any
+<application>gpsd</application>-aware client application.</para>
+
+<para>Logfiles for the use with <application>gpsfake</application> can
+be retrieved using <application>gpspipe</application>,
+<application>gpscat</application>, or
+<application>gpsmon</application> from the gpsd distribution, or any
+other application which is able to create a compatible output.</para>
+
+<para>If <application>gpsfake</application> exits with "Cannot execute
+gpsd: executable not found." the environment variable GPSD_HOME can be
+set to the path where gpsd can be found. (instead of adding that folder
+to the PATH envirnment variable</para>

+
+<para><application>gpsmon</application> is a monitor that watches
+packets coming from a GPS and displays them along with diagnostic
+information. It supports commands that can be used to tweak GPS
+settings in various ways; some are device-independent, some vary
+with the GPS chipset type.</para>
+
+<para>This tool used to be called 'sirfmon', and worked only on SiRF
+devices (and the command set has changed to resemble the command
+switches of <application>gpsctl</application>). It now has support for a range
+of NMEA devices as well; support for other (binary-protocol) device
+types is planned. It will behave sanely, just dumping packets, when
+connected to a GPS type it knows nothing about.</para>
+
+<para><application>gpsmon</application> differs from a navigation
+client in that it mostly dumps raw data from the GPS, with only enough
+data-massaging to allow checks against expected output.  In
+particular, this tool does not do any interpolation or modeling
+to derive climb/sink or error estimates. Nor does it discard 
+altitude reports when the fix quality is too low.</para>
+
+<para><application>gpsmon</application> is a designed to run in a
+terminal emulator with a minimum 25x80 size; the non-GUI interface is
+a design choice made to accommodate users operating in constrained
+environments and over telnet or ssh connections.  If run in a larger
+window, the size of the packet-log window will be increased to
+fit.</para>
+
+<para><application>gpsmon</application> accepts an -h option that
+displays a usage message, or a -V option to dump the package
+version and exit.</para>
+
+<para>This program may be run in either of two modes, as a client for
+the <application>gpsd</application> daemon (and its associated control
+socket) or directly connected to a specified serial device.  When run
+with no argument, it attempts to connect to the daemon.  If the
+argument looks like a server:port specification it will also attempt
+to connect to the daemon.  If the argument looks like a bare server
+name it will attempt to connect to a daemon running on the default
+gpsd port on that server.  Only if the device argument contains
+slashes but no colons will it be treated as a serial device for direct
+connection. In direct-connect mode <application>gpsmon</application>
+will hunt for a correct baud rate and lock on to it
+automatically.</para>
+
+<para>The -F option is only valid in client mode; it specifies a
+control socket to which the program should send device control
+strings.  You must specify a valid pathname of a Unix-domain socket on
+your local filesystem.</para>
+
+<para>The -D option enables packet-getter debugging output and is
+probably only useful to developers of the GPSD code.  Consult the
+packet-getter source code for relevant values.</para>
+
+<para>The -L option lists a table showing which GPS device types
+<application>gpsmon</application> has built-in support for, and which
+generic commands can be applied to which GPS types, and then
+exits. Note that this does not list type-specific commands associated
+with individual GPS types.</para>
+
+<para>The -l option sets up logging to a specified file to start
+immediately on device open.  This may be useful is, for example,
+you want to capture the startup message from a device that displays
+firmware version information there.</para>
+
+<para>After startup, the top part of the screen reports the contents
+of several especially interesting packet types.  The bottom half of
+the screen is a scrolling hex dump of all packets the GPS is issuing.
+Dump lines beginning &gt;&gt;&gt; represent control packets sent to the
+GPS.</para>

+
+<para>The following device-independent comands are available while 
+<application>gpsmon</application> is running:</para>
+
+<variablelist>
+
+<varlistentry>
+<term>i</term>
+<listitem>
+<para>Enable/disable subtype probing and reinitialize the driver. In
+normal operation, <application>gpsmon</application> does not send
+configuration strings to the device (except for wakeup strings needed
+to get it to send data, if any). The command 'i1' causes it to send
+the same sequence of subtype probes that
+<application>gpsd</application> would.  The command 'i0' turns off
+probing; 'i' alone toggles the bit. In either case, the current driver
+is re-selected; if the probe bit is enabled, probes will begin to be
+issued immediately.</para>
+
+<para>Note that enabling probing might flip the device into another
+mode; in particular, it will flip a SiRF chip into binary mode as if
+you had used the <quote>n</quote> command.  This is due to a
+limitation in the SiRF firmware that we can't fix.</para>
+</listitem>
+</varlistentry>
+
+<varlistentry>
+<term>c</term>
+<listitem>
+<para>Change cycle time. Follow it with a number interpreted as a
+cycle time in seconds. Most devices have a fixed cycle time of 1
+second, so this command may fail with a message.</para>
+</listitem>
+</varlistentry>
+
+<varlistentry>
+<term>l</term>
+<listitem>
+<para>Toggle packet logging. If packet logging is on, it will be
+turned off and the log closed.  If it is off, logging to the filename
+following the l will be enabled.  Differs from simply capturing the
+data from the GPS device in that only whole packets are logged.
+The logfile is opened for append, so you can log more than one
+portion of the packet stream and they will be stitched together
+correctly.</para>
+</listitem>
+</varlistentry>
+
+<varlistentry>
+<term>n</term>
+<listitem>
+<para>With an argument of 0, switch device to NMEA mode at current
+speed; with an argument of 1, change to binary (native) mode. With no
+argument, toggle the setting. Will show an error if the device doesn't
+have such modes.</para>
+</listitem>
+</varlistentry>

+<term>q</term>
+<listitem>
+<para>Quit <application>gpsmon</application>.  Control-C, or whatever
+your current interrupt chracter is, works as well.</para>
+</listitem>
+</varlistentry>
+
+<varlistentry>
+<term>s</term>
+<listitem>
+<para>Change baud rate. Follow it with a number interpreted as bits
+per second, for example "s9600". The speed number may optionally be
+followed by a colon and a wordlength-parity-stopbits specification in
+the traditional style, e.g 8N1 (the default), 7E1, etc.  Some
+devices don't support serial modes other than their default, so
+this command may fail with a message.</para>
+
+<para>Use this command with caution.  On USB and Bluetooth GPSes it is
+also possible for serial mode setting to fail either because the
+serial adaptor chip does not support non-8N1 modes or because the
+device firmware does not properly synchronize the serrial adaptor chip
+with the UART on the GPS chipset whjen the speed changes. These
+failures can hang your device, possibly requiring a GPS power cycle or (in
+extreme cases) physically disconnecting the NVRAM backup battery.</para>
+</listitem>
+</varlistentry>
+
+<varlistentry>
+<term>t</term>
+<listitem>
+<para>Force a switch of monitoring type. Follow it with a string that
+is unique to the name of a gpsd driver with
+<application>gpsmon</application> support;
+<application>gpsmon</application> will switch to using that driver and
+display code. Will show an error message if there is no matching gpsd
+driver, or multiple matches, or the unique match has no display
+support in <application>gpsmon</application>.</para>

+payload of a control packet shipped to the device. The packet will be
+wrapped with headers, trailers, and checksum appropriate for the

+says <quote>Static navigation is a position filter designed to be used
+with motor vehicles.  When the vehicle's velocity falls below a
+threshold, the position and heading are frozen, and velocity is set to
+zero. This condition will continue until the computed velocity rises
+above 1.2 times the threshold or until the computed position is at
+least a set distance from the frozen place. The threshold velocity and
+set distance may vary with software versions.</quote></para>
+
+<para>Non-static mode is designed for use with road navigation
+software, which often snaps the reported position to the nearest road
+within some uncertainty radius.  You probably want to turn static

+
+<para><application>gpspipe</application> does not require root
+privileges, and can be run concurrently with other tools connecting
+to the local <application>gpsd</application> without causing problems.</para>
+
+<para>The output will consist of one or both of the raw NMEA or native
+<application>gpsd</application> sentences.  Each line can be optionally
+time stamped.  There is also an option to exit gracefully after a
+given count of packets.</para>
+
+<para>Optionally a server, TCP/IP port number and remote device can be given.
+If omitted, <application>gpspipe</application> connects to localhost on
+the default port (2947) and watches all devices opened by

+
+<para>-h makes <application>gpspipe</application> print
+a usage message and exit.</para>
+
+<para>-d causes <application>gpspipe</application> to run as a daemon.</para>
+
+<para>-l causes <application>gpspipe</application> to sleep for ten
+seconds before attempting to connect to gpsd.  This is very useful
+when running as a daemon, giving gpsd time to start before
+attempting a connection.</para>
+
+<para>-r causes raw NMEA sentences to be output.</para>
+
+<para>-R causes super-raw (gps binary) data to be output.  This overrides
+NMEA and gpsd output modes.</para>
+
+<para>-s option causes the collected data to be written to the
+specified serial device with settings 4800 8N1.  Thus
+<application>gpspipe</application> can be used with -s and -r options
+to emulate a serial port hardwired to a GPS that
+<application>gpsd</application> is managing.</para>
+
+<para>-o option causes the collected data to be written to the
+specified file.  Use of this option is mandatory
+if <application>gpspipe</application> is run as a daemon.</para>
+
+<para>-w causes native <application>gpsd</application>sentences to be

+
+<para>-T sets the format of the timestamp. See

+
+<para>-n [count] causes [count] sentences to be output.  
+<application>gpspipe</application> will then exit gracefully.</para>
+
+<para>-v causes <application>gpspipe</application> to show a spinning
+activity indicator on stderr. This is useful if stdout is redirected
+into a file or a pipe. By default the spinner is advanced with every
+messages written; specifying -v more than once will double the number
+of messages required to rotate the spinner.</para>

+
+<para><application>gpsprof</application> measures the various
+latencies between a GPS and its client. It emits to standard output a
+GNUPLOT program that draws an illustrative graph. It can also be told
+to emit the raw profile data.  The information it provides can be
+useful for establishing an upper bound on latency, and thus on
+position accuracy of a GPS in motion.</para>
+
+<para><application>gpsprof</application> uses instrumentation built
+into <application>gpsd</application>.</para>
+
+<para>To display the graph, use
+<citerefentry><refentrytitle>gnuplot</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+Thus, for example, to display the default spatial scatter plot, do
+this:
+
+<programlisting>
+gpsprof | gnuplot -persist
+</programlisting>
+</para>
+
+</refsect1>
+<refsect1 id='options'><title>OPTIONS</title>
+
+<para>The -f option sets the plot type. The X axis is samples
+(sentences with timestamps).  The Y axis is normally latency in seconds.
+Currently the following plot types are defined:</para>
+
+<variablelist>
+<varlistentry>
+<term>space</term>
+<listitem>
+<para>Generate a scattergram of fixes and plot a probable-error
+circle.  This data is only meaningful if the GPS is held stationary
+while <application>gpsprof</application> is running. 
+This is the default.</para>
+<para></para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>uninstrumented</term>
+<listitem>
+<para>Plot total latency without instrumentation.  Useful mainly as a
+check that the instrumentation is not producing significant
+distortion.  It only plots times for sentences that contain fixes;
+staircase-like artifacts in the plot are created when elapsed time
+from sentences without fixes is lumped in.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>raw</term>
+<listitem>
+<para>Plot raw data.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>split</term>
+<listitem>
+<para>Each sentence has its RS232 latency time colored differently.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>cycle</term>
+<listitem>
+<para>Report on the set of sentences or packets emitted by the GPS,
+their send intervals, and the basic cycle time. (This report is 
+plain text rather than a gnuplot script.)</para>
+</listitem>
+</varlistentry>
+</variablelist>
+
+<para>The instrumented time plot conveys the following information:</para>
+
+<variablelist>
+<varlistentry>
+<term>RS232 time</term>
+<listitem>
+<para>Time required to send the sentence from the GPS to
+<application>gpsd</application>. This measured from the time of 
+the last zero-length read before the packet to when the packet sniffer
+recognizes a complete sentence, so there is a small aountt of
+computational overhead mixed in.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>Decode time</term>
+<listitem>
+<para>Elapsed time between sentence reception and the moment that
+<application>gpsd</application> ships the resulting update to
+the profiling client.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term>TCP/IP latency</term>
+<listitem>
+<para>Elapsed time between the moment that
+<application>gpsd</application> ships the update to
+the profiling client and the moment it is decoded and timestamped.</para>
+</listitem>
+</varlistentry>
+</variablelist>
+
+<para>Because of RS232 buffering effects, the profiler sometimes
+generates reports of ridiculously high latencies right at the
+beginning of a session.  The -m option lets you set a latency threshold, in
+multiples of the cycle time, above which reports are discarded.</para>
+
+<para>The -n option sets the number of packets to sample.  The default
+is 100.</para>
+
+<para>The -s option sets the baud rate.  Note, this will only work if
+the chipset accepts a speed-change command (SiRFstarII and SiRFstarIII
+support this feature).</para>
+
+<para>The -t option sets a text string to be included in the plot
+title.</para>
+
+<para>The -h option makes <application>gpsprof</application> print 
+a usage message and exit.</para>
+
+<para>The -D sets debug level.</para>

+    a(k, 3) = sin el(k)
+
+Then form the line-of-sight matrix A for satellites used in the solution:
+
+    | a(1,1) a(1,2) a(1,3) 1 |
+    | a(2,1) a(2,2) a(2,3) 1 |
+    |   :       :      :   : |
+    | a(n,1) a(n,2) a(n,3) 1 |
+
+And its transpose A~:
+
+    |a(1, 1) a(2, 1) .  .  .  a(n, 1) |
+    |a(1, 2) a(2, 2) .  .  .  a(n, 2) |
+    |a(1, 3) a(2, 3) .  .  .  a(n, 3) |
+    |    1       1   .  .  .     1    |
+
+Compute the covariance matrix (A~*A)^-1, which is guaranteed symmetric:
+
+    | s(x)^2    s(x)*s(y)  s(x)*s(z)  s(x)*s(t) |
+    | s(y)*s(x) s(y)^2     s(y)*s(z)  s(y)*s(t) |
+    | s(z)*s(x) s(z)*s(y)  s(z)^2     s(z)*s(t) |
+    | s(t)*s(x) s(t)*s(y)  s(t)*s(z)  s(t)^2    |
+
+Then:
+
+GDOP = sqrt(s(x)^2 + s(y)^2 + s(z)^2 + s(t)^2)
+TDOP = sqrt(s(t)^2)
+PDOP = sqrt(s(x)^2 + s(y)^2 + s(z)^2)
+HDOP = sqrt(s(x)^2 + s(y)^2)
+VDOP = sqrt(s(z)^2)
+
+Here's how we implement it...
+
+First, each compute element P(i,j) of the 4x4 product A~*A.
+If S(k=1,k=n): f(...) is the sum of f(...) as k varies from 1 to n, then
+applying the definition of matrix product tells us:
+
+P(i,j) = S(k=1,k=n): B(i, k) * A(k, j)
+
+But because B is the transpose of A, this reduces to
+
+P(i,j) = S(k=1,k=n): A(k, i) * A(k, j)
+
+This is not, however, the entire algorithm that SiRF uses.  Carl writes:
+
+> As you note, with rounding accounted for, most values agree exactly, and
+> those that don't agree our number is higher.  That is because we
+> deweight some satellites and account for that in the DOP calculation.
+> If a satellite is not used in a solution at the same weight as others,
+> it should not contribute to DOP calculation at the same weight.  So our
+> internal algorithm does a compensation for that which you would have no
+> way to duplicate on the outside since we don't output the weighting
+> factors.  In fact those are not even available to API users.
+
+Queried about the deweighting, Carl says:
+
+> In the SiRF tracking engine, each satellite track is assigned a quality
+> value based on the tracker's estimate of that signal.  It includes C/No
+> estimate, ability to hold onto the phase, stability of the I vs. Q phase
+> angle, etc.  The navigation algorithm then ranks all the tracks into
+> quality order and selects which ones to use in the solution and what
+> weight to give those used in the solution.  The process is actually a
+> bit of a "trial and error" method -- we initially use all available
+> tracks in the solution, then we sequentially remove the lowest quality
+> ones until the solution stabilizes.  The weighting is inherent in the
+> Kalman filter algorithm.  Once the solution is stable, the DOP is
+> computed from those SVs used, and there is an algorithm that looks at
+> the quality ratings and determines if we need to deweight any.
+> Likewise, if we use altitude hold mode for a 3-SV solution, we deweight
+> the phantom satellite at the center of the Earth.
+
+So we cannot exactly duplicate what SiRF does internally.  We'll leave
+HDOP alone and use our computed values for VDOP and PDOP.  Note, this
+may have to change in the future if this code is used by a non-SiRF
+driver.

+/*****************************************************************************
+
+This is a decoder for the unnamed protocol described in IS-GPS-200,
+the Navstar GPS Interface Specification, and used as a transport layer
+for both GPS satellite downlink transmissions and the RTCM104 version 2 
+format for broadcasting differential-GPS corrections.
+
+The purpose of this protocol is to support analyzing a serial bit
+stream without byte framing into parity-checked packets.
+Interpretation of the packets is left to an upper layer. Note that
+RTCM104 version 3 does *not* use this code; it assumes a byte-oriented
+underlayer.
+
+The upper layer must supply a preamble_match() hook to tell our
+decoder when it has a legitimate start of packet, and a length_check()
+hook to tell it when the packet has reached the length it is supposed
+to have.
+
+Here are Wolfgang's original rather cryptic notes on this code:
+
+--------------------------------------------------------------------------
+1) trim and bitflip the input.
+
+While syncing the msb of the input gets shifted into lsb of the
+assembled word.  
+    word <<= 1, or in input >> 5 
+    word <<= 1, or in input >> 4
+    word <<= 1, or in input >> 3
+    word <<= 1, or in input >> 2 
+    word <<= 1, or in input >> 1 
+    word <<= 1, or in input
+
+At one point it should sync-lock.
+
+----
+
+Shift 6 bytes of RTCM data in as such:
+
+---> (trim-bits-to-5-bits) ---> (end-for-end-bit-flip) ---> 
+
+---> shift-into-30-bit-shift-register

+              detector-for-parity
+              |||||||||||||||||||||||
+--------------------------------------------------------------------------
+
+The code was originally by Wolfgang Rupprecht.  ESR severely hacked
+it, with Wolfgang's help, in order to separate message analysis from
+message dumping and separate this lower layer from the upper layer 
+handing GPS and RTCM decoding.  
+
+You are not expected to understand any of this.

+
+NAME
+   json.c - parse JSON into fixed-extent data structures
+
+DESCRIPTION
+   This module parses a large subset of JSON (JavaScript Object
+Notation).  Unlike more general JSON parsers, it doesn't use malloc(3)
+and doesn't support polymorphism; you need to give it a set of
+template structures describing the expected shape of the incoming
+JSON, and it will error out if that shape is not matched.  When the
+parse succeds, attribute values will be extracted into static
+locations specified in the template structures.
+
+   The "shape" of a JSON object in the type signature of its
+attributes (and attribute values, and so on recursively down through
+all nestings of objects and arrays).  This parser is indifferent to
+the order of attributes at any level, but you have to tell it in
+advance what the type of each attribute value will be and where the
+parsed value will be stored. The template structures may supply
+default values to be used when an expected attribute is omitted.
+
+   The dialect this parses has some limitations.  First, it cannot
+recognize the JSON "null" value.  Secondly, arrays may only have
+objects or strings - not reals or integers or floats - as elements
+(this limitation could be easily removed if required). Third, all
+elements of an array must be of the same type.
+
+   There are separata entry points for beginning a parse of either
+JSON object or a JSON array. JSON "float" quantities are actually
+stored as doubles.
+
+   This parser processes object arrays in one of two different ways,
+defending on whether the array subtype is declared as object or
+structobject.
+
+   Object arrays take one base address per object subfield, and are 
+mapped into parallel C arrays (one per subfield).  Strings are not
+supported in this kind of array, as the don't have a "natural" size
+to use as an offset multiplier.
+
+   Structobjects arrays are a way to parse a list of objects to a set
+of modifications to a corresponding array of C structs.  The trick is
+that the array object initialization has to specify both the C struct
+array's base address and the stride length (the size of the C struct).
+If you initialize the offset fields with the correct offsetof() calls,
+everything will work. Strings are suppported but all string storage
+has to be inline in the struct.

+
+<para><emphasis remap='B'>libgps</emphasis> is a service library which
+supports communicating with an instance of the
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>8</manvolnum></citerefentry>; link it with the linker option -lgps.</para>
+
+<warning><para>Take care to conditionalize your code on the major and
+minor API version symbols in <filename>gps.h</filename>; ideally,
+force a compilation failure if GPSD_API_MAJOR_VERSION is not a version
+you recognize.  See the GPSD project website for more information on
+the protocol and API changes.</para></warning>
+
+<para>Calling <function>gps_open()</function> initializes a GPS-data
+structure to hold the data collected by the GPS, and returns a socket
+attached to
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>1</manvolnum></citerefentry>. 
+<function>gps_open()</function> returns NULL on errors.  errno is
+set depending on the error returned from the the socket layer; see
+<filename>gps.h</filename> for values and explanations. The host
+address may be a DNS name, an IPv4 dotted quad, or an IPV6 address;
+the library will do the right thing for any of these.</para>
+
+<para><function>gps_open_r()</function> is a reentrent-friendly
+version that puts the session storage where you wish to allocate it.
+It returns 0 on success and -1 on failure, with errno set
+appropriately.</para>
+
+<para><function>gps_close()</function> ends the session.</para>
+
+<para><function>gps_send()</function> writes a command to the daemon.
+The second argument must be a format string containing elements from
+the command set documented at
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+It may have % elements as for
+<citerefentry><refentrytitle>sprintf</refentrytitle><manvolnum>3</manvolnum></citerefentry>,
+which will be filled in from any following arguments.  This function
+returns a -1 if there was a Unix-level write error, otherwise
+0. Please read the LIMITATIONS section for additional information and
+cautions.</para>
+
+<para><function>gps_poll()</function> accepts a response, or sequence
+of responses, from the daemon and interprets it as though it were a
+query response (the return value is as for a query).
+<function>gps_poll()</function> returns the validity mask of the
+received structure.  This function does a blocking read waiting for
+data from the daemon; it returns 0 for success, -1 with errno set on a 
+Unix-level read error, -1 with errno not set if the socket to
+the daemon has closed. </para>
+
+<para><function>gps_waiting()</function> can be used to check
+whether there is data from the daemon. It returns true if there is,
+false on no data waiting or error condition. It does not block
+waiting for input.</para>
+
+<para><function>gps_stream()</function> asks
+<application>gpsd</application> to stream the reports it has at you,
+to be made available whenn you poll.  It is preferable to the
+older-style (pre-2.90) way of doing this,
+<function>gps_query()</function> with a "w+" argument, because it
+insulates your code from whether your client library and your
+<application>gpsd</application> are using old or new protocol.
+The second argument is a flag mask that sets various policy bits; 
+see trhe list below.  Calling <function>gps_stream()</function>
+more than once with different flag masks is allowed.</para>

+<para><function>gps_set_raw_hook()</function> takes a function you

+call.  The arguments passed to this hook will be a pointer to a

+
+<para><function>gps_errstr()</function> returns an ASCII string (in
+English) describing the error indicated by a nonzero return value from

+
+<para>Consult <filename>gps.h</filename> to learn more about the data members 
+and associated timestamps.  Note that information will accumulate
+in the session structure over time, and the 'valid' field is not
+automatically zeroed by each poll.  It is up to the client to
+zero that field when appropriate and to keep an eye on the fix 
+and sentence timestamps.</para>
+
+<para>The Python implementation supports the same facilities as the C
+library. <function>gps_open()</function> is replaced by the
+initialization of a gps session object; the other calls are methods of
+that object, and have the same names as the corresponding C functions.
+Resources within the session object will be properly released when it
+is garbage-collected. Note one limitation: POLL_NOBLOCK is not yet 
+supported in Python; use the waiting() method instead.</para>

+may lead to subtle bugs. In order to not bloat <structname>struct
+gps_data_t</structname> with space used by responses that are not
+expected to be shipped in close sequence with each other, the storage
+for fields associated with certain responses are combined in a
+union.</para>
+
+<para>The risky set of responses includes VERSION, DEVICELIST, RTCM2,
+RTCM3, and AIS; it may not be limited to that set.  The logic of the
+daemon's watcher mode is careful to avoid dangerous sequences, but
+you should read and understand the layout of <structname>struct
+gps_data_t</structname> before using <function>gps_send()</function>
+to request any of these responses.</para>

+
+<para>The <function>gps_query()</function> supported in major versions
+1 and 2 of this library has been removed.  With the new
+streaming-oriented wire protocol behind this library, it is extremely
+unwise to assume that the first transmission from the damon after a
+command is shipped to it will be the reponse to command.</para>
+
+<para>If you must send commands to the daemon explicity, use
+<function>gps_send()</function> but beware that this ties your code to
+the GPSD wire protocol. It is not recommended.</para>
+
+<para>This API has been stable since GPSD 2.90, except that
+<function>gps_waiting()</function> was added in 2.91.</para>

+<refsect1 id='description'><title>DESCRIPTION</title>
+<para><emphasis remap='B'>libgpsd</emphasis>
+is a service library which supports querying GPS devices; link it with
+the linker option -lgpsd.  It is a set of low-level
+device-handling calls, which
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+itself uses.  See 
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>3</manvolnum></citerefentry>
+for a description of the high-level interface, which is almost
+certainly what you want.</para>
+
+<para>Calling
+<function>gpsd_init()</function>
+initializes a session structure to hold the data collected by the GPS.</para>
+
+<para>The second argument must be a context structure.  The library 
+will use it for information that need to be shared between sessions; 
+presently this includes the leap-second correction and possibly a
+pointer to a shared-memory segment used to communicate with the
+Network Time Protocol daemon.</para>
+
+<para>After the session structure has been set up, you may modify some
+of its members.</para>
+
+<variablelist>
+<varlistentry>
+<term><structfield>gpsd_device</structfield></term>
+<listitem>
+<para>This member should hold the path name of the device.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term><structfield>baudrate</structfield></term>
+<listitem>
+<para>Communication speed in bits per second.  For NMEA or SiRF devices, the
+library automatically hunts through all plausible baud rates, stopping
+on the one where it sees valid packets.  By setting this field you can
+designate a speed to be tried at the front of the hunt queue</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term><structfield>raw_hook</structfield></term>
+<listitem>
+<para>A hook function to be executed on each NMEA
+sentence or as it is read from the GPS.  The data from non-NMEA GPSes like
+the EarthMate will be translated to an NMEA sentence before being
+passed to the hook.  Parameters are a pointer to a gps_data structure
+full of parsed data, the sentence, and the length of the sentene..</para>
+</listitem>
+</varlistentry>
+</variablelist>
+
+<para><function>gpsd_activate()</function>
+initializes the connection to the GPS. 
+<function>gpsd_deactivate()</function>
+closes the connection. These functions are provided so that
+long-running programs can release a connection when there is no
+activity requiring the GPS, and re-acquire it later.</para>
+
+<para><function>gpsd_poll()</function>
+queries the GPS and updates the part of the session structure that
+holds position, speed, GPS signal quality, and other data returned
+by the GPS. It returns a mask describing which fields have changed.</para>
+
+<para><function>gpsd_wrap()</function>
+ends the session, implicitly performing a 
+<function>gpsd_deactivate()</function>.</para>
+
+<para>The calling application must define one additional function:
+<function>gpsd_report()</function>.
+The library will use this to issue ordinary status messages.  Use 
+first argument of 0 for errors, 1 for ordinary status messages,
+and 2 or higher for debugging messages.</para>
+
+<para>The low-level functions do not allocate or free any dynamic 
+storage.  They can thus be used in a long-running application (such as
+<citerefentry><refentrytitle>gpsd</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+itself) with a guarantee that they won't cause memory leaks.</para>

+<para><emphasis remap='B'>libgpsmm and libQgpsmm</emphasis> are mere wrappers over
+	<emphasis remap='B'>libgps</emphasis>. The important difference between the libraries is that libgpsmm is targeted at C++ applications and contained in <emphasis remap='B'>libgps</emphasis>, while libQgpsmm is platform independant by using QTcpSocket to connect to <emphasis remap='B'>gpsd</emphasis> and shipped as an additional library due to the necessary linking to QT.
+Method names are the same as
+the analogue C functions. For a detailed description of the functions
+please read
+<citerefentry><refentrytitle>libgps</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
+<function>open()</function> must be called after class constructor and before any other method
+(<function>open()</function> is not inside the constructor since it may fail, however constructors have no return value).
+The analogue of the C function <function>gps_close()</function> is in the destructor.</para>

+ *

+ * Its logics for the creation of ntpshm segments are:
+ *
+ * Segments 0 and 1: permissions 0600, i.e. other programs can only
+ *                   read and write as root.
+ *
+ * Segments 2 and 3: permissions 0666, i.e. other programs can read
+ *                   and write as any user.  I.e.: if ntpd has been
+ *                   configured to use these segments, any 
+ *                   unpriviliged user is allowed to provide data 
+ *                   for synchronisation.
+ *
+ * As gpsd can be started as both root and non-root, this behaviour is
+ * mimiced by:
+ *
+ * Started as root: do as ntpd when attaching (creating) the segments.
+ * (In contrast to ntpd, which only attaches (creates) configured
+ * segments, gpsd creates all segments.)
+ *
+ * Started as non-root: only attach (create) segments 2 and 3 with
+ * permissions 0666.  As the permissions are for any user, the creator
+ * does not matter.
+ *
+ * For each GPS module gpsd controls, it will use the attached ntpshm
+ * segments in pairs (for coarse clock and pps source, respectively)
+ * starting from the first found segments.  I.e. started as root, one
+ * GPS will deliver data on segments 0 and 1, and as non-root data
+ * will be delivered on segments 2 and 3.
+ *
+ * to debug, try looking at the live segments this way
+ *  ipcs -m
+ * results  should look like this:
+ * ------ Shared Memory Segments --------
+ *  key        shmid      owner      perms      bytes      nattch     status

+ *
+ * For a bit more data try this:
+ *  cat /proc/sysvipc/shm
+ *
+ * If gpsd can not open the segments be sure you are not running SELinux

+%description clients
+xgps is a simple test client for gpsd with an X interface. It displays
+current GPS position/time/velocity information and (for GPSes that
+support the feature) the locations of accessible satellites.
+
+xgpsspeed is a speedometer that uses position information from the GPS.
+It accepts an -h option and optional argument as for gps, or a -v option
+to dump the package version and exit. Additionally, it accepts -rv
+(reverse video) and -nc (needle color) options.
+
+cgps resembles xgps, but without the pictorial satellite display.  It
+can run on a serial terminal or terminal emulator.

+%description 
+gpsd is a service daemon that mediates access to a GPS sensor
+connected to the host computer by serial or USB interface, making its
+data on the location/course/velocity of the sensor available to be
+queried on TCP port 2947 of the host computer.  With gpsd, multiple
+GPS client applications (such as navigational and wardriving software)
+can share access to a GPS without contention or loss of data.  Also,
+gpsd responds to queries with a format that is substantially easier to
+parse than NMEA 0183.

+/****************************************************************************
+
+NAME:
+   packet.c -- a packet-sniffing engine for reading from GPS devices
+
+DESCRIPTION:
+
+Initial conditions of the problem:
+
+1. We have a file descriptor open for (possibly non-blocking) read. The device
+   on the other end is sending packets at us.
+
+2. It may require more than one read to gather a packet.  Reads may span packet
+   boundaries.
+
+3. There may be leading garbage before the first packet.  After the first
+   start-of-packet, the input should be well-formed.
+
+The problem: how do we recognize which kind of packet we're getting?
+
+No need to handle Garmin USB binary, we know that type by the fact we're
+connected to the Garmin kernel driver.  But we need to be able to tell the
+others apart and distinguish them from baud barf.

+/*
+ * The packet-recognition state machine.  This takes an incoming byte stream
+ * and tries to segment it into packets.  There are three types of packets:
+ *
+ * 1) Comments. These begin with # and end with \r\n.
+ *
+ * 2) NMEA lines.  These begin with $, and with \r\n, and have a checksum.
+ *
+ * 3) Binary packets.  These begin with some fixed leader character(s),
+ *    have a length embedded in them, and end with a checksum (and possibly)
+ *    some fixed trailing bytes.  
+ *
+ * 4) ISGPS packets. The input may be a bitstream containing IS-GPS-200
+ *    packets.  Each includes a fixed leader byte, a length, and check bits.  
+ *    In this case, it is not guaranted that packet starts begin on byte 
+ *    bounaries; the recognizer has to run a separate state machine against 
+ *    each byte just to achieve synchronization lock with the bitstream.
+ *
+ * Adding support for a new GPS protocol typically reqires adding state
+ * transitions to support whatever binary packet structure it has.  The
+ * goal is for the lexer to be able to cope with arbitrarily mixed packet
+ * types on the input stream.  This is a requirement because (1) sometimes
+ * gpsd wants to switch a device that supports both NMEA and a binary
+ * packet protocol to the latter for more detailed reporting, and (b) in
+ * the presence of device hotplugging, the type of GPS report coming
+ * in is subject to change at any time.
+ *
+ * Caller should consume a packet when it sees one of the *_RECOGNIZED
+ * states.  It's good practice to follow the _RECOGNIZED transition
+ * with one that recognizes a leader of the same packet type rather
+ * than dropping back to ground state -- this for example will prevent
+ * the state machine from hopping between recognizing TSIP and
+ * EverMore packets that both start with a DLE.
+ *
+ * Error handling is brutally simple; any time we see an unexpected
+ * character, go to GROUND_STATE and reset the machine (except that a
+ * $ in an NMEA payload only resets back to NMEA_DOLLAR state).  Because
+ * another good packet will usually be along in less than a second
+ * repeating the same data, Boyer-Moore-like attempts to do parallel
+ * recognition beyond the headers would make no sense in this
+ * application, they'd just add complexity.
+ *
+ * The NMEA portion of the state machine allows the following talker IDs:
+ *      GP -- Global Positioning System.
+ *      GL -- GLONASS, according to IEIC 61162-1
+ *      GN -- Mixed GPS and GLONASS data, according to IEIC 61162-1
+ *      II -- Integrated Instrumentation (Raytheon's SeaTalk system).
+ *	IN -- Integrated Navigation (Garmin uses this).

+<refsect1 id='overview'><title>OVERVIEW</title>
+
+<para>RTCM-104 is a family of serial protocols used for broadcasting pseudorange
+corrections from differential-GPS reference stations.  This manual
+page describes some aspects of the RTCM protocol, mainly in order to
+explain the RTCM-104 dump formats emitted by
+<citerefentry><refentrytitle>gpsdecode</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
+It describes that dump format completely.</para>
+
+<para>RTCM-104 comes in two major and incompatible flavors, 2.x and
+3.x.  Each major flavor has minor (compatible) revisions.</para>
+
+<para>The applicable standard for RTCM Version 2.x is <citetitle>RTCM
+Recommended Standards for Differential NAVSTAR GPS Service</citetitle>
+RTCM Paper 194-93/SC 104-STD. For RTCM 3.1 it is <citetitle>RTCM Paper
+177-2006-SC104-STD</citetitle>.  Ordering instructions for both
+standards are accessible from the website of the <ulink
+url='http://www.rtcm.org/'>Radio Technical Commission for Maritime
+Services</ulink> under "Publications".</para>
+
+</refsect1>
+<refsect1 id='wire-format'><title>RTCM WIRE TRANSMISSIONS</title>
+
+<para>Differential-GPS correction stations consist of a GPS reference
+receiver coupled to a low frequency (LF) transmitter.  The GPS
+reference receiver is a survey-grade GPS that does GPS carrier
+tracking and can work out its own position to a few millimeters.  It
+generates range and range-rate corrections and encodes them into
+RTCM104. It ships the RTCM104 to the LF transmitter over serial rs-232
+signal at 100 baud or 200 baud depending on the requirements of the
+transmitter.</para>
+
+<para>The LF transmitter broadcasts the the approximately 300khz radio
+signal that differential-GPS radio receivers pick up.  Transmitters
+that are meant to have a higher range will need to transmit at the
+slower rate.  The higher the data rate the harder it will be for the
+remote radio receiver to receive with a good signal-to-noise ration.
+(Higher data rate signals can't be averaged over as long a time frame,
+hence they appear noisier.)</para>
+
+</refsect1>
+<refsect1 id='rtcm-wire-format'><title>RTCM WIRE FORMATS</title>
+
+<para>An RTCM 2.x message consists of a sequence of up to 33 30-bit
+words. The 24 most significant bits of each word are data and the six
+least significant bits are parity. The parity algorithm used is the
+same ISGPS-2000 as that used on GPS satellite downlinks.  Each RTCM
+2.x message consists of two header words followed by zero or more data
+words, depending upon message type.</para>
+
+<para>An RTCM 3.x message begins with a fixed leader byte 0xD3.  That
+is followed by six bits of version information and 10 bits of payload
+length information.  Following that is the payload; following the 
+payload is a 3-byte checksum of the payload using the Qualcomm CRC-24Q
+algorithm.</para>

+<refsect1 id='sager-dump-format2'><title>SAGER RTCM2 DUMP FORMAT</title>
+
+<para>For each message, the header is listed first, followed by zero
+or more lines containing the specific data for that message, followed
+by a trailing sentinel line containing a single dot. The general format is a
+line beginning with a capital letter, followed by a tab, followed by
+the fields of the message separated by tabs, terminated by a

+that it is in GPS time, which is some seconds ahead of UTC (see the
+U.S. Naval Observatory's <ulink
+url="ftp://maia.usno.navy.mil/ser7/tai-utc.dat">table of leap second
+corrections</ulink>).</para>
+
+<para>&lt;sequence no&gt; is a number which increments, modulo 8, for each
+message transmitted.</para>
+
+<para>&lt;message length&gt; is the number of words after the header that
+comprise the message.</para>
+
+<para>&lt;station health&gt; indicates the health of the beacon as a
+reference source.  Any nonzero value means the satellite is probably
+transmitting bad data and should not be used in a fix. 6 means the
+transmission is unmonitored. 7 means the station is not working
+properly. Other values are defined by the beacon operator.
+</para>
+
+<para>If the message contains a parity error after the header but before
+the end of the message, then the extra fields [T &lt;useful length&gt;]
+are appended to indicate a truncated message.</para>

+</literallayout>
+
+<para>&lt;iod&gt; is Issue Of Data, matching the IOD for the current

+is a unique tag that identifies the ephemeris; the GPS using the DGPS
+correction and the DGPS generating the data must use the same orbital
+positions for the satellite.</para>
+
+<para>&lt;modified z_count&gt; is just a copy of the same field from
+the header.</para>
+
+<para>&lt;range error&gt; is the pseudorange error in meters for this satellite
+as measured by the beacon reference receiver at the epoch indicated
+by &lt;modified z_count&gt;</para>
+
+<para>&lt;range error rate&gt; is the rate of change of pseudorange error in
+meters/sec for this satellite as measured by the beacon reference
+receiver at the epoch indicated by &lt;modified z_count&gt;. This is
+used to calculate pseudorange errors at other epochs, if
+required by the GPS receiver.</para>

+
+<para>&lt;dat&gt; is 0 or 1 and indicates the sense of the offset

+(in the reference message) are referred to a local datum and that
+adding dx, dy, dz to that position will render it in GNSS coordinates
+(WGS84 for GPS). If dat = 1 then the ref station position is in GNSS
+coordinates and adding dx, dy, dz will give it referred to the local
+datum.</para>
+
+<para>&lt;datum name&gt; is a standard name for the datum.</para>

+	 * be very sure you know what you're doing before hacking it, and
+	 * test thoroughly.
+	 *
+	 * The fundamental problem here is that serial devices take time
+	 * to settle into a new baud rate after tcsetattr() is issued. Until
+	 * they do so, input will be arbitarily garbled.  Normally this
+	 * is not a big problem, but in our hunt loop the garbling can trash
+	 * a long enough prefix of each sample to prevent detection of a
+	 * packet header.  We could address the symptom by making the sample
+	 * size enough larger that subtracting the maximum length of garble
+	 * would still leave a sample longer than the maximum packet size.
+	 * But it's better (and more efficient) to address the disease.
+	 *
+	 * In theory, one might think that not even a tcflush() call would
+	 * be needed, with tcsetattr() delaying its return until the device
+	 * is in a good state.  For simple devices like a 14550 UART that
+	 * have fixed response timings this may even work, if the driver
+	 * writer was smart enough to delay the return by the right number
+	 * of milliseconds after poking the device port(s).
+	 *
+	 * Problems may arise if the driver's timings are off.  Or we may
+	 * be talking to a USB device like the pl2303 commonly used in GPS
+	 * mice; on these, the change will not happen immediately because
+	 * it has to be sent as a message to the external processor that
+	 * has to act upon it, and that processor may still have buffered
+	 * data in its own FIFO.  In this case the expected delay may be
+	 * too large and too variable (depending on the details of how the
+	 * USB device is integrated with its symbiont hardware) to be put
+	 * in the driver.
+	 *
+	 * So, somehow, we have to introduce a delay after tcsatattr()
+	 * returns sufficient to allow *any* device to settle.  On the other
+	 * hand, a really long delay will make gpsd device registration
+	 * unpleasantly laggy.
+	 *
+	 * The classic way to address this is with a tcflush(), counting
+	 * on it to clear the device FIFO. But that call may clear only the
+	 * kernel buffers, not the device's hardware FIFO, so it may not
+	 * be sufficient by itself.
+	 *
+	 * flush followed by a 200-millisecond delay followed by flush has
+	 * been found to work reliably on the pl2303.  It is also known
+	 * from testing that a 100-millisec delay is too short, allowing
+	 * occasional failure to lock.

+
+<para>Motorola S-records are a form of simple ASCII encoding for
+binary data.  This format is commonly used for firmware uploads to
+GPSes, industrial robots, and other kinds of microcontroller-driven
+hardware.  It has several convenient properties, including
+inspectability, easy editing with any text editor, and checksumming
+for verification of transmission across noisy serial lines.</para>
+
+<para>An S-record file consists of a sequence of specially formatted
+ASCII character strings. An S-record will be less than or equal to 78
+bytes in length.</para>
+
+<para>The order of S-records within a file is of no significance and
+no particular order may be assumed.</para>
+
+<para>The general format of an S-record follows:</para>
