NAME
cgps - curses terminal client for gpsd
SYNOPSIS
cgps [OPTIONS] [server[:port[:device]]]
cgps -h
cgps -V
DESCRIPTION
cgps is an ncurses based gpsd client. It is able to run on a serial
terminal or terminal emulator. It resembles xgps(1), but without the
pictorial satellite display and does not require X or other windowing
system.
cgps does not require root privileges. It will also run fine as root.
Running under sudo will cause loss of functionality.
None of the error estimates provided by gpsd, and displayed by cgps,
should be taken as anything other than "goodness" levels. GNSS receiver
manufactures often do not document the basis for their estimates. Those
that do document their estimates are inconsistent about what they mean.
OPTIONS
-?, -h, --help
Print a summary of options and then exit.
-D LVL, --debug LVL
Sets the debug level; it is primarily for use by GPSD developers. It
enables various progress messages to standard error.
-i, --imu
Show IMU instead of fix and satellite data.
-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.
-m, --magtrack
Display tracks as magnetic, not true.
-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.
-s, --silent
Prevents cgps from displaying the raw data coming from the daemon.
This display can also be toggled with the s command.
-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.
-V, --version
Print the package version and exit.
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
COMMANDS
cgps terminates when you send it a SIGHUP or SIGINT; given default
terminal settings this will happen when you type Ctrl-C at it.
cgps will accept a few single letter commands while running:
c
Clear the bottom window.
d
Show lat/lon dd.dddddddd, dd mm.mmmmmm and dd mm ss.ssss
h
Popup a help window.
i
Use imperial units.
m
Use metric units.
n
Use nautical units.
q
Clear screen and exit
s
Toggle showing raw JSON data in the bottom window.
t
Toggle true/magnetic track.
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
0
on success.
1
on failure
