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:

CAS-4A
• Linear transponder downlink 145.870 MHz, emission designator
20K0V8WWF, power 20 dBm
• Linear transponder uplink 435.220 MHz
• CW telemetry 145.855 MHz, emission designator 100HA1AAN, output power 17 dBm
• GMSK telemetry 145.835 MHz, emission designator 16K0F1DCN, output power 20 dBm

CAS-4B
• Linear transponder downlink 145.925 MHz, emission designator
20K0V8WWF, power 20 dBm
• Linear transponder uplink 435.280 MHz
• CW telemetry 145.910 MHz, emission designator 100HA1AAN, power 17 dBm
• GMSK telemetry 145.890 MHz, emission designator 16K0F1DCN, power 20 dBm

Bom dia !
