ads-b

A Clojure wrapper for java-libadsb, which parses Mode S/ADS-B transponder messages. (See also: dump1090, gr-air-modes, etc.)

Caveats

java-libadsb only decodes a few types of Mode S messages, and no Mode A/C messages.

Civil aviation uses Mode S messages with types DF0, DF4, DF5, DF11, DF16, DF17, DF18, DF20, DF21 and DF24; java-libadsb only decodes some subtypes of DF17 and DF18.
