Setting up an APRS iGate with the RTL-SDR

Over on Pawel Janowski’s blog (SQ7MRU) a writeup on how to set up an APRS iGate receiver with an RTL-SDR and cubieboard mini computer has been posted. The article has been written in Polish, but can be translated using Google Translate.

APRS stands for Automatic Packet Reporting System and is usually used by Amateur radio operators to broadcast the current GPS coordinates of something such as a transmitter site/car/boat or high altitude amateur balloon. These APRS packets are received by an iGate and then put onto the internet. Check out aprs.fi for an example.

To create an APRS iGate, Pawel runs a RTL-SDR compatible python program called pymultimonaprs which is used to receive and broadcast the APRS data on to the internet.
