Hi, I’ve been playing with decoding ADSB for a while. While dump1090 does a really great job, the code is - uhm - an acquired taste. I’ve just released my GNU Radio blocks for a ADSB framer and decoder (both written in Python) along with an example flowgraph (see: [GitHub - wnagele/gr-adsb: GNU Radio ADSB decoder and framer](https://github.com/wnagele/gr-adsb)). They are not feature complete and I welcome feedback. I’ve tested it with a HackRF and RTL SDR dongles - both work fine as they both support the Osmocom source. The main reason I have done this was to decode a protocol end-to-end and pull together the required information. I find that the biggest challenge with almost anything SDR and GNU Radio related is that there is only bits and pieces of information available but rarely something that works end-to-end and explains what’s going on. For that reason I have also described the various stages of this flowgraph in detail ([https://github.com/wnagele/gr-adsb/tree/master/examples](https://github.com/wnagele/gr-adsb/tree/master/examples)).
