The GPS Signal can be obtained and used via different ways:

• Webinterface
• GPS over IP
• cli status interface
• inside of SDK Skripts

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:

• on request (clients must send R after connect to get NMEA frames)
• in raw mode (clients are served directly with NMEA frames after connection)
• in super raw mode (clients are served directly with NMEA frames after connection)
• in JSON mode (the new JSON interface is provided to clients after connection)

// 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.

Via the Command Line Interface you can aquire also the gps parameters:

                               Model: ME909u-521
                               Revision: 11.235.07.00.00
                               IMEI: 860461024127634
                               +GCAP: +CGSM

To have it in the right format for using inside of scripts (bash, python etc.) you can use the parameter “-s”
