CAS-4A and CAS-4B Frequencies Coordinated
CAMSAT has worked closely with a Beijing Government aerospace contractor to build two satellites with amateur radio linear transponder payloads
IARU record a launch had been planned for March 31, 2017 from Taiyuan into a 524 km orbit with an inclination of 42 degrees.
Both will carry a 435/145 (U/V) 20 dBm (100 milliwatt) SSB/CW linear transponder, a 2m CW 17 dBm (50 mW) telemetry beacon and an AX.25 4.8 kbps GMSK 20 dBm (100 mW) telemetry downlink.
The two micro-satellites will also carry optical remote sensing missions. Planned to be 494x499x630 mm dimension regular square shape and approximately 50 kg mass with three-axis stabilization system.
These frequencies have been coordinated by the IARU Satellite Frequency Coordination Panel:
