http://hackaday.com/2016/06/10/gnu-radio-for-space-and-aircraft/

GOMX-3 is a CubeSat with several payloads. One of them is a software defined radio configured to read ADS-B signals sent by commercial aircraft. The idea is that a satellite can monitor aircraft over oceans and other places where there no RADAR coverage. ADB-S transmits the aircraft’s ID, its position, altitude, and intent.

The problem is that ADS-B has a short-range (about 80 nautical miles). GOMX-1 proved that the signals can be captured from orbit. GOMX-3 has more capability. The satellite has a helical antenna and an FPGA.

The people behind the satellite, GomSpace, has a complete parser for the ADS-B data beacons and [destevez] has it rolled into a GNU Radio module.
