.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
The
\fB\-j\fR
option tells the daemon to hold fix data across cycles, eliminating jitter from NMEA sevices that emit several partial reports (see the
\fB\-s\fR
for a client\-side way to do something similar).
.PP
The
\fB\-l\fR
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.
.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'.
.SS "cgps"
.PP
cgps
is a client resembling
xgps, but without the pictorial satellite display and able to run on a serial terminal or terminal emulator.
.PP
The
\fB\-s\fR
option prevents
cgps
from printing the raw data. This display can also be toggled with the s command.
.PP
The
\fB\-j\fR
option tells the daemon not to clear data at start of cycle, eliminating jitter from NMEA sevices that emit several partial reports per cycle.
.PP
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:
.sp
.nf
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
.fi
.PP
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'
.PP
The 'j' command toggles whether or not fix data is cleared at start of cycle; see
\fBgpsd\fR(8)
for discussion.
.SS "cgpxlogger"
.PP
This program connects to gpsd, polls for location, and logs each fix to standard output in GPX (XML) format.
.PP
The program also writes start and end messages to syslog.
.SS "gpxlogger"
.PP
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.
.PP
The output may be composed of multiple tracks. A new track is created if there's no fix for 5 seconds.
.PP
The program also writes start and end messages to syslog.
