The GPS Signal can be obtained and used via different ways:
The Webinterface already give you access to the GPS Data. This can be suitable to have a quick look on the current status of a vehicle.
Via Status→GNSS you will see this Overview
Via Interfaces→GNSS you will see this Map
We use version 3.9 of gpsd as a GPS via IP Daemon
We support the following modes:
// get JOSN ?WATCH={'enable':true,'json':true} // get NMEA ?WATCH={'enable':true,'json':false} ?WATCH={'enable':true,'nmea':true}
For more information on the new JSON interface see http://www.catb.org/gpsd/client-howto.html
Linux clients are cgps
, gpsmon
and gpspipe.
You can install them via apt-get install gpsd-clients
To see the NMEA Data you can also use any telnet emulator of your choice: putty
, hyperterminal
etc.
