1090-to-owntracks

This small program slurps the data from aircraft.json as produced by tedsluis/dump1090 which is a Mode S decoder for RTLSDR devices.

Data is published to the MQTT topic ot/flights/<flightnumber> in OwnTracks-compatible JSON:

{
  "tst": 1474648272,
  "cog": 134,
  "lon": 6.658383,
  "_type": "location",
  "flight": "KLM1963",
  "roc": 0,
  "lat": 51.381042,
  "_geoprec": 2,
  "alt": 10058,
  "vel": 877,
  "name": "KLM1963"
}
