Collection of satellite telemetry signal decoders


This GNU Radio out-of-tree module can be used to decode frames transmitted from most Amateur satellites in orbit, performing demodulation, forward error correction, etc. Decoded frames can be saved to a file or displayed in hex format. For some satellites the telemetry format definition is included in gr-satellites, so the decoded telemetry frames can be printed out as human-readable values such as bus voltages and currents. Additionally, some satellites transmit files such as JPEG images. gr-satellites can be used to reassemble these files and even display the images in real-time as they are being received.

It supports most popular protocols, such as AX.25, the GOMspace NanoCom U482C and AX100 modems, an important part of the CCSDS stack, the AO-40 protocol used in the FUNcube satellites, and several ad-hoc protocols used in other satellites.

This package contains the header files and grc block definitions, and a set of satellite telemetry decoding scripts.
