summary

An open source GNU Radio out‑of‑tree module that aims to decode nearly 40 satellites actually provides concrete decoders for AX.25, the GOMspace NanoCom U482C and AX100, parts of the CCSDS stack and AO‑40/FUNcube formats, started in 2015 and implemented in GNU Radio OOT module blocks in Python and C++. Inputs are UDP audio (14‑bit 48 kHz) or recordings, outputs are PDUs/hex and parsed telemetry; it reassembles JPEGs (demo with LilacSat‑1) and is used in at least one SatRevolution integration.
