CAS-5A Amateur Radio Satellite

The CAMSAT CAS-5A amateur radio satellite was piggybacked on the Smart Dragon-3 Y1 launch vehicle and launched from the sea launch platform in the Yellow Sea at UTC 06:35:02 on December 9, 2022. After 724 seconds, the satellite successfully separated from the launch vehicle and entered the intended orbit. The satellite orbit is a circular sun-synchronous orbit with an altitude of 543 kilometers and an inclination of 97.53 degrees, the running cycle is 95.575minutes. AMSAT has designated CAS-5A satellite as Fengtai-OSCAR 118 (FO-118). CAMSAT CAS-5A Amateur Radio Satellite - fig
1 The functions of CAS-5A satellite include UHF CW telemetry beacon, GMSK telemetry data transmission, V/U mode linear transponder, V/U mode FM transponder, H/U mode linear transponder, three visible light band space cameras.After the satellite completes the in-orbit test and works normally, the space camera photo download will be open to amateur radio enthusiasts all over the world. When the relevant remote control command is received by the satellite, the GMSK telemetry channel will be used to downlink the photo catalog and photo data, and the telemetry data will stop sending at that time.
CAS-5A satellite adopts a 6U CubeSat structure with a mass of about 7kg, an on-orbit envelope size of 366x226x100mm (antennas not included) with six sides body-mounted solar panels and a three-axis stabilized attitude control system is used, long-term power consumption is about 10 Watts.
