ARLS005 China to Launch CAMSAT CAS-6 Satellite on December 20
The CAMSAT CAS-6 amateur radio payload is set for launch on Friday,
December 20, at 0321 UTC from the Taiyuan Satellite Launch Center,
piggybacked on a TIANQIN-1 technology test satellite, using a CZ-4B
launch vehicle. The primary launch payload is the China-Brazil Earth
Resources Satellite CBERS-4A.
The microsatellite, to be known as CAS-6/TIANQIN-1, will be placed
into a Sun-synchronous orbit at an apogee of 390 miles. It will
operate on VHF and UHF using the call sign BJ1SO. The telemetry
beacon is on 145.910 MHz, while telemetry (4k9 baud GMSK) will be
transmitted on 145.890 MHz. CAS-6 will carry a U/V linear
transponder, with a downlink of 145.925, 20 kHz passband (inverted),
and an uplink of 435.280 MHz.
CAMSAT has provided CAS-6 Satellite Digital Telemetry Description
and CW Telemetry Beacon Encoding Format documents available in PDF
