DESCRIPTION

   xgps
       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.

       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.
       Diamond icons indicate WAAS/EGNOS satellites, circles indicate ordinary
       GPS satellites. Filled icons were used in the last fix, outline icons
       were not.

       xgps accepts an -h option as for gpsd, or a -V option to dump the
       package version and exit.

       An optional argument 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 device name to be handed to
       the daemon in an F= command.

       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. This option can also be set as the X resource ´speedunits´.

       The -altunits option can be used to set the altitude units for display;
       follow the keyword with ´meters´ or ´feet´. The default is feet. This
       option can also be set as the X resource ´altunits´.

       The -j option tells the daemon to hold fix data across cycles,
       eliminating jitter from NMEA devices that emit several partial reports.
       The downside is that with this switch on the client will occasionally
       report stale or invalid data held over from a previous cycle. This
       option is ineffective, and not needed, on SiRFs and most other non-NMEA
       GPSes.

       The -l option 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.

       There is a known bug in xgps; it assumes the default font size is no
       more than 18 pixels. If this is not the case, the satellite data
       display will show fewer than 12 satellites.

   xgpsspeed
       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.

       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. This option can also be set as the X resource ´speedunits´.

   cgps
       cgps is a client resembling xgps, but without the pictorial satellite
       display and able to run on a serial terminal or terminal emulator.

       The -s option prevents cgps from printing the raw data. This display
       can also be toggled with the s command.

       The -j option is as described for xgps above.

       Rather than use X resources to determine which units to use, cgps looks
       at variables in its environment. Here are the variables and values it
       checks:

               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

       cgps 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´

       The ´j´ command toggles whether or not fix data is cleared at start of
       cycle; see the description of the -j of xgps (above) and gpsd(8) for
       discussion.

   cgpxlogger
       This program connects to gpsd, polls for location, and logs each fix to
       standard output in GPX (XML) format.

       The -s and -p options can be used to specify a server and port to
       query.

       The -i option sets the poll interval at which the logger will collect
       samples.

       The -j option is as described for xgps above.

       The -h option causes the program to emit a summary of its options and
       then exit.

       The program also writes start and end messages to syslog.

   gpxlogger
       This program listens to DBUS broadcasts from gpsd (org.gpsd.fix) and
       logs each fix to standard output as they arrive in an XML format.

       The output may be composed of multiple tracks. A new track is created
       if there´s no fix for 5 seconds.

       The program also writes start and end messages to syslog.
