This paper by Daniel Est\u00e9vez EA4GPZ, Mario Lorenz DL5MLO and Peter G\u00fclzow DB2OS describes the reception of the Tianwen-1 Chinese Mars mission carried out by AMSAT-DL with the 20 meter antenna at Bochum Observatory (Germany). A real-time GNU Radio decoder has been used to receive and store telemetry almost every day over the course of 10 months. Some of the telemetry variables, such as the trajectory information, have been successfully interpreted and used to track the progress of the mission.<\/span><\/p>\n
