NAME

       gps2udp - feed the take from gpsd to one or more aggregation sites

SYNOPSIS

       gps2udp [OPTIONS] [server[:port[:device]]]

       gps2udp -h

       gps2udp -V

DESCRIPTION

       gps2udp is a tool to connect to gpsd and output the received sentences to one or many UDP
       host:port destinations. This makes the program useful for feeding AIS information from
       gpsd to aishub, marinetraffic, shipfinder,...

       gps2udp does not require root privileges, but can run as root. It can be run concurrently
       with other tools connecting to the local gpsd without causing problems.

       The output will consist of one or both of NMEA (-n option) or JSON (-j option) gpsd
       sentences. The output is sent to one or many destinations host through a UDP network
       socket (-u HOST:PORT options) .

       Optionally a server, TCP/IP port number and remote device can be given. If omitted,
       gps2udp connects to localhost on the default port (2947) and watches all devices opened by
       gpsd.

       gps2udp may be run as a daemon (-b option).

       gps2udp is designed to run smoothly in background; it reconnects automatically to gpsd
       whenever it is restarted. For debugging purporses, there is an option to exit gracefully
       after a given count of packets (-c option).

OPTIONS

       -?, -h, --help
           -Print a usage message and exit.

       -a, --ais
           Send only AIS messages.

       -b, --daemon
           Causes gps2udp to run as a daemon.

       -c COUNT, --count COUNT
           Exit after COUNT sentences are sent.

       -d LVL, --debug LVL
           Set debug level to LVL. LVL = 0 prints nothing. LVL = 1 prints sent packet on stdout.
           LVL = 2 prints ignored packets.

       -j, --json
           Causes JSON sentences to be output.

       -n, --nmea
           Causes NMEA sentences to be output.

       -t, --tpv
           Only output TPV sentences. Implies --json.

       -u HOST:PORT, --udp HOST:PORT
           UDP destination for output sentenses (up to five destinations).

       -v, -V, --version
           Prints the program version, then exit. -v is deprecated December 2020.

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

EXAMPLES

       With a running gpsd accessible on the network this will collect data from localhost:gpsd
       display them on stdout and send a copy to test aishub in NMEA format.

           gps2udp -d 1 -n -u data.aishub.net:2222

       This will collect data from a remote gpsd located on fridu.net host, will filter AIS
       messages and send them to 3 destinations (aishub, marinetraffic, shipfinder) in NMEA
       format, while running in background mode

           gps2udp -a -n -b -u data.aishub.net:2222 -u 5.9.207.224:5321 \
              -u 109.200.19.151:4001 fridu.net:2947

RETURN VALUES

       0
           on success.

       1
           on failure
