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
