a (graphical) manager of GPS data


gpsman [-dev [usb=]DEVICE]
gpsman [Options] COMMAND [COMMAND_ARGS]


gpsman GPS Manager (GPSMan) is a graphical manager of GPS data that makes possible the preparation, inspection and edition of GPS data in a friendly environment. GPSMan supports communication and real-time logging with Garmin, Lowrance and Magellan receivers and accepts real-time logging information in NMEA 0183 from any GPS receiver.

To comunicate with the GPS port the user must have been granted read/write permissions for the corresponding device.

For use in graphical mode GPSMan must be invoked as in the first form above, where the usb= prefix to the device path enforces the use of the Garmin USB protocol. The use in this mode is not further described here, a full description being given in the User Manual available along with the GPSMan distribution.

GPSMan can also be used in command line mode (with no graphical interface), in which case it must be invoked as in the second form above. The sections below address this mode.

Exit Status

In non-graphical mode GPSMan exits with either a 0 if COMMAND was successfully executed, or a 1 if not. Some commands will write information to the standard output channel. Error messages can possibly be written to the standard error channel, but most of the errors will not be explained. In case of doubt the graphical mode should be used to see if there are problems with files or the receiver.


Apart from the -dev option all other options are only for use in non-graphical mode.

-dev DEVICE gives the device path.
-log creates a log file of the serial communication

under the name logfile in the GPSMan user directory.

-rec Garmin | Lowrance | Magellan

changes the brand of the receiver (NOTE: at present will only work with Garmin); this option can be useful to override the options in the preferences file; cannot be used with the readput command, nor with the -prefs option, and cannot occur after the -prot option.


gives the path for an alternative preferences file (read after the user preferences file); cannot be used with the -rec option.


selects the protocol to be used for connecting to the receiver; cannot occur before the -rec option; the show protocols command can be used to find out which protocols are available.

Options not related with COMMAND will be silently ignored.

Name=Value Arguments

Some commands accept parameters in the form NAME=VALUE. The term PARAM when used here referring to arguments of a command has always this meaning. Care should be taken if the value part is a string with spaces (or other characters with special meaning for the shell or system command interpreter) in which case quotes or some other form of quoting should be used.

Gpsman Command Summary

There is no room in a manual page to describe in detail the available commands. The following list gives a synopsis for all of them:

is available exits with 0.
is connected

exits with 0 if a connection check with the receiver succeeds.

show WHAT writes help information to the standard output; WHAT is one of: datums, formats (data file formats), help, projections, protocols, symbols (waypoint symbols), transfs

(coordinates transformations).

haslib LIBRARY checks availability of library

getwrite INTYPES FORMAT [OUTTYPES] [OUTPARAMS] PATH transfers data from the receiver to a file.

readput FORMAT [INPARAMS] [INTYPES] PATH [OUTTYPES] transfers data from a file to the receiver.

getrtimelog PATH [INTERVAL] gets the real-time log from the receiver and saves it to a file.

getfix PATH [TIMEOUT] gets the current fix data from the receiver and saves it to a file.

getalmanac PATH gets the current almanac data from the receiver and saves it to a file.

read IN-FORMAT [PARAMS] [TYPES] PATH reads a data file and launches the graphical interface (in GPSMan scripts the behaviour is different; see the exec command in the user manual).

start travel [INTERVAL] launches the graphical interface and starts real-time logging, animation and travelling.

translate FORMAT [INPARAMS] [INTYPES] PATH [HOWPARAMS] FORMAT [OUTPARAMS] [OUTTYPES] PATH translates from a file format to another.

project LATD LONGD DATUM PROJECTION [PARAMS] writes to the standard output the projection of a point.

georef IMGPATH TRANSF LATD LONGD LATD LONGD [LATD LONGD] DATUM X Y X Y [X Y] PROJECTION [PARAMS] writes to the standard output a map information file.

geopicts FORMAT [INPARAMS] INTYPE PATH [PROCPARAMS] [FORMAT] [OUTPARAMS] PATH PICTPATHS geo-references files either based on their time-stamps and a given track, or by using the sequence of waypoints in a group.

source PATH executes a Tcl/Tk script.

exec PATH executes a GPSMan script.
