gr-air

This GNU Radio component implements common aircraft datalink protocols such as Mode Select, ADS-B, and TIS-B. ACARS will be done in the future.

Current status (18/10/09)

This has been partially updated to use GNU Radio 3.2. Mode S decoding and dumping does work (USRP1 with DBSRX), although only with such a low gain that packets are almost invisible on a scope display.

Files
