CAS-4A and CAS-4B Satellites from CAMSAT Launched today


Two CAMSAT’s armature radio payloads piggybacked on the optical remote sensing micro-satellites OVS-1A and OVS-1B have been launched at 11:00BJT on June 15, 2017 at The Jiuquan Satellite Launch Center of China, using CZ-4B launch vehicle. The primary of this launch is a hard X-ray modulation telescope satellite (HXMT).
