NAME gpxloggerd – GPX logging daemon

SYNOPSIS gpxloggerd [-dhVv] [-D level] [-f template] [-u user [:group]] [-p pidfile] [-m meters] [-M meters] [-a degrees] [-I interval] [-i timeout] [server [:port [:device]]]

DESCRIPTION The gpxloggerd is a tiny daemon that connects to GPSD(8) and logs received fix information in the GPX format. By default the gpxloggerd connects to GPSD(8) at the localhost:2947 and logs to stdout GPX data for all GPS devices served be the daemon.

 The options are as follows:

 -h      Print usage and exit.

 -V      Print version number and exit.

 -v      Be as verbose as possible when writing GPX log.  For now this
         means logging of ⟨fix⟩, ⟨sat⟩, ⟨hdop⟩, ⟨vdop⟩ and ⟨pdop⟩ fields,
         which bloats size of produced GPX significantly.  By default this
         option is turned off, and only coordinates, time and elevation
         are logged.

 -d      Detach from terminal and become a daemon.

 -D level
         Set the underlying libgps(3) library to the given debug level.

 -f template
         Write data to the given file instead of stdout.  The template
         isn't a bare filename, but can be a format for the strftime(3).

 -u user [:group]
         Lower the daemon priveleges to the specified user and group.

 -p pidfile
         Write the daemon pid to the specified file.

 -m meters
         Suppress logging of track segment in case if it lays within the
         specified distance away from the previous logged track segment.
         This option is useful to avoid polluted GPX traces at parking
         lots and other places, where vehicle stands still for long time.
         The option is turned off by default.

 -a degrees
         Suppress logging of track segment unless the course (azimuth,
         bearing) of the vehicle has changed to a value equal or greater
         than the specified angle in degrees.  This option is useful to
         make traces on straight roads more sparse.  The option is turned
         off by default.

 -M meters
         Set maximum track segment length.  This option is meaningful only
         in conjunction with the -a option.  The default value is 200
         meters.

 -i timeout
         Start new track if the time jump between current fix and previous
         logged one is above the timeout. By default timeout value is 300
         seconds.

 -I interval
         Specify logging interval between trackpoints in seconds.  The
         default one is one second.

 When the gpxloggerd daemon receives SIGHUP it finalizes GPX in the
 current output file, closes it and then starts a new one using the
 configured template as a file name.
