NAME
xgps, xgpsspeed, cgps - test clients for gpsd
SYNOPSIS
xgps [X-options] [-h] [-v] [-speedunits {mph | kph | knots}]
[-altunits {feet | meters}] [-l [d | m | s]] [server [:port
[:device]]]
xgpsspeed [-rv] [X-options] [-h] [-v] [-nc X-color]
[-speedunits {mph | kph | knots}] [server [:port [:device]]]
cgps [-h] [-v] [-speedunits {mph | kph | knots}]
[-altunits {feet | meters}] [-l [d | m | s]] [server [:port
[:device]]]
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.
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 -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.
Rather than use X resources to detemine 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’
