DESCRIPTION

       These are some simple clients shipped with gpsd. They have some common options:

       -?, -h, --help
           Print a summary of options and then exit.

       -V, --version
           Print the package version and exit.

       By default, clients collect data from all compatible devices on localhost, using the
       default 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 only parsed after the trailing bracket. Possible
       cases look like this:

       localhost:/dev/ttyS1
           Look at the default port of localhost, trying both IPv4 and IPv6 and watching output
           from serial device 1.

       example.com:2317
           Look at port 2317 on example.com, trying both IPv4 and IPv6.

       71.162.241.5:2317:/dev/ttyS3
           Look at port 2317 at the specified IPv4 address, collecting data from attached serial
           device 3.

       [FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:2317:/dev/ttyS5
           Look at port 2317 at the specified IPv6 address, collecting data from attached serial
           device 5.

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

       -D LVL, --debug LVL
           Sets the debug level; it is primarily for use by GPSD developers. It enables various
           progress messages to standard error.

       -l FMT, --llfmt FMT
           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.

       -s, --silent
           Prevents cgps from displaying the data coming from the daemon. This display can also
           be toggled with the s command.

       -m, --magtrack
           Display your magnetic track (as opposed to your true track). This is a calculated
           value, not a measured value. Magnetic variation is always potentially subject to large
           errors, but is usually better than two degrees.

       -u UNITS, --units UNITS
           Set the system units for display; follow the keyword with 'i' for 'imperial' for
           American units (International 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, kilometers per hour in
           speeds).

           Note: The USA Survey Foot is not supported.

       cgps terminates when you send it a SIGHUP or SIGINT; given default terminal settings this
       will happen when you type Ctrl-C at it. It will also terminate on 'q'

   gegps
       This program collects fixes from gpsd and feeds them to a running instance of Google Earth
       for live location tracking.

       -d DIR, --kmldir DIR
           Specify the location of the Google Earth installation directory. If not specified, it
           defaults to the current directory.

       -D LVL, --debug LVL
           Sets the debug level; it is primarily for use by GPSD developers. It enables various
           progress messages to standard error.

       --device DEVICE
           Connect to device DEVICE on gpsd host.

       --host HOST
           Connect to gpsd on host HOST.

       -i, --initialize
           If you have the free (non-subscription) version, start by running with the -i option
           to drop a clue in the Google Earth installation directory, as
           'Open_in_Google_Earth_RT_GPS.kml', then open that file in Places (File > Open...). Run
           gegps in the normal way after that.

       --port PORT
           Connect to gpsd on port PORT.

   lcdgps
       A client that passes gpsd data to lcdproc, 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.

       -s, --sleep
           Sleep for 10 seconds before starting.

ENVIRONMENT

       The environment variable GPSD_UNITS is checked if no unit system is specified on the
       command line. It may be set to 'i'. 'imperial', 'm', 'metric', or 'n', 'nautical'.

       LC_MEASUREMENT and then LANG are checked if no unit system has been specified on the
       command line, or in GPSD_UNITS. If the value is 'C', 'POSIX', or begins with 'en_US' the
       unit system is set to imperial. The default if no system has been selected defaults to
       metric.
