For nearly one year, the German amateur satellite association AMSAT-DL has regularly been decoding the telemetry of the Chinese Mars probe Tianwen-1 using the 20m antenna at Bochum observatory and GNU Radio. This has allowed us to obtain updated orbital information from the spacecraft and receive the relayed signals during the landing of the Zhurong rover. To our best knowledge, this is a record of using GNU Radio for receiving digital communications at a distance greater than 300 million km.
