Global Positioning Systems (GPS)

NOTE: For more information about GPS configurations, see http://locationd.readthedocs.io/en/latest/intro.html.

National Marine Electronics Association (NMEA) data is supported if the GPS module is present in the system. In the operating system, the

location service is a central hub for multiplexing access to positioning subsystems available through hardware and software. It provides a

client API offering positioning capabilities to applications and other system components..

To retrieve NMEA streaming data:

• Device node for NMEA streaming: Edge Gateway 3001/3003

$ cat /dev/ttyS4

To access location service:

$ sudo locationd.monitor
