.SH "DESCRIPTION"

.SS "xgps"

.PP
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\&.

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

.PP
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\&.

.PP
The \fB\-speedunits\fR 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'\&.

.PP
The \fB\-altunits\fR 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'\&.

.PP
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\&.

.SS "xgpsspeed"

.PP
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\&.

.PP
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'\&.
