APRS tracker and communicator for mobile devices written in python / elementary. Targeted especially for the Openmoko Freerunner it utilizes FSO freesmartphone middleware framework. Tested and used on SHR, where atrack is in repos, so to install type: opkg install atrack

Atrack can also track on different services, i.e. support for youloc.net, but then it acts as a dumb tracker.

Please note that usage within the aprs network requires amateur radio license, but for non-commercial usage you can run your own FOSS aprsd server http://sourceforge.net/projects/aprsd/, this is given by the license of the APRS protocol, both aprsd server and atrack are FOSS). You can also run a fake small perl script server PrivateAPRS_IS_FakeServer
