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

       gps2udp [-h] [-n] [-j] [-a] [-u hostname:udpport] [-c count] [-d	1|2]
	       [-v] [server [:port [:device]]]

       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,

       gps2udp does not	require	root privileges, and 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).

       -h makes	gps2udp	print a	usage message and exit.

       -n causes NMEA sentences	to be output.

       -j causes JSON sentences	to be output.

       -u host:port UDP	destination for	output sentenses (up to	five

       -a output only AIS messages.

       -b causes gps2udp to run	as a daemon.

       -c [count] causes [count] sentences to be output.  gps2udp will then
       exit gracefully.

       -d 1 prints sent	packet on stdout.

       -d 2 prints unsent packet on stdout.

       -v prints the version, then exits.

       With a running gpsd accessible on the network

       gps2udp -d 1 -n -u will collect data from
       localhost:gpsd display them on stdout and send a	copy to	test aishub in
       NMEA format.

       gps2udp -a -n -b	-u	-u -u will collect data from a remote gpsd
       located on host, will filter AIS messages and send them to 3
       destination (aishub, marinetraffic, shipfinder) in NMEA format, command
       is running in background	mode

       gpsd(8),	gps(1),	libgps(3), libgpsmm(3),	gpsprof(1), gpsfake(1),
       gpsctl(1), gpscat(1).  gpsmon(1).
