NAME¶

xgpsspeed - X speedometer for gpsd

SYNOPSIS¶

xgpsspeed [OPTIONS] [service[:port[:device]]]

xgpsspeed -h

xgpsspeed -V

DESCRIPTION¶

xgpsspeed is a speedometer that uses position information from gpsd.

The default display mode is a speed and track presentation modeled after a marine navigation display; for backward compatibility the --nautical option forces this mode. The --landspeed option produces a simple speedometer.

The --speedunits option can be used to set the speed units for display; follow the keyword with "knots" for nautical miles per hour, "kmh" for kilometers per hour, or "mph" for miles per hour. The default is miles per hour.

In the nautical mode only, --maxspeed sets the maximum on the speedometer.

xgpsspeed will run fine as a normal user, and fine as root. Running xgpsspeed under sudo will cause some loss of functionality.

OPTIONS¶

-?, -h, --help

-device DEVICE

-D LVL, --debug LVL

--host HOST

-p PORT, --port PORT

-V, --version

ARGUMENTS¶

By default, clients collect data from the local gpsd daemon running on localhost, using the default GPSD port 2947. The optional argument to any client may override this behavior: [server[:port[:device]]]

For further explanation, and examples, see the ARGUMENTS section in the gps(1) man page

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.

RETURN VALUES¶
