Two New Chinese Ham Satellites Expected to Launch in September


Two new Chinese amateur radio satellites are expected to launch on September 15. CAS-7A and CAS-7C follow in the wake of numerous amateur radio satellites put into space by CAMSAT. CAS-7A, a 27 kilogram microsat, will carry several transponders, including a 15-meter-to-10-meter (H/T) linear transponder, and a 2-meter-to-70-centimeter (H/U) linear transponder. CAS-7A also will include a V/U (2 meters to 70 centimetres) FM voice transponder. According to the International Amateur Radio Union (IARU) satellite coordination site, CAS-7A is planned to have CW beacons on both 10 meters and 70 centimetres, 4.8k or 9.6k GMSK telemetry on 70 centimetres, and a 1 Mbps GMSK image data downlink on 3 centimetres for an onboard camera.
