Fox-1D to launch with Fox-1C on Spaceflight SHERPA 1Q 2016

In response to a breaking opportunity, AMSAT and Spaceflight, Inc. have arranged for Fox-1D to accompany Fox-1Cliff on the maiden flight of the SHERPA system on a SpaceX Falcon 9. As a Fox-1 series, Fox-1D is identical to Fox-1Cliff, but with different frequencies and carrying the University of Iowa HERCI (High Energy Radiation CubeSat Instrument) radiation mapping experiment as a hosted payload. Fox-1D will provide additional selectable U/V or L/V repeater capabilities once in orbit, and will be capable of downlinking Earth images from the Virginia Tech camera experiment. Launch is currently planned for the first quarter of 2016. Additional donor support is needed to offset the costs associated with the launch of Fox-1D in addition to Fox-1Cliff. Please visit www.amsat.org to donate support this launch, and help keep amateur radio in space.

CAMSAT announces mid-July launch with six U/V transponders

Alan Kung, BA1DU (CAMSAT CEO) recently sent AMSAT-NA a stunning press release, copied in full below:

CAMSAT orchestrated CAS-3 amateur satellite system is now nearing completion, six Chinese amateur satellites will be launched in mid-July,it includes different weight category satellites, consists of a 20 kg, three 10 kg and two 1 kg satellites. All six satellites are equipped with substantially the same amateur radio payloads, a U/V mode linear transponder, a CW telemetry beacon and an AX.25 19.2k/9.6k baud GMSK telemetry downlink are attached in each of the six satellites, each set of amateur radio equipments has the same technical characteristics, but operates on different frequencies of 70cm band uplink and 2m band downlink.

During the years, CAMSAT works closely with DFH Satellite Co. Ltd to complete the project, which is Chinese government aerospace contractor and provided most of the support for this project. All the satellites are currently conducting final testing and inspection, here are the technical details:

– Mass: 1.5kg
– Stabilization: Spinning stabilization using permanent magnet torquer
– Antenna: Deployable antenna, one 1/4λ monopole VHF antenna with max.0dBi gain is located at +Z side and one 1/4λ monopole UHF antenna with max.0dBi gain is located at –Z side, close to the each edge of satellite body
– Uplink: 70cm band
– Downlink: 2m band
– Amateur radio payloads:
Callsign: BJ1SF ( for CAS-3E), BJ1SG ( for CAS-3F)
CW Telemetry Beacon: 50mW, 22wpm
U/V Mode Linear Transponder: 100mW, 20kHz bandwidth, spectrum Inverting
AX.25 telemetry: 100mW, 9.6k baud GMSK

This launch will use an brand new Chinese launch vehicle named as Long March – 6 (LM-6 or CZ-6) at Taiyuan Satellite Launch Center of China, CAS-3A will operate at about 450 km height sun-synchronous orbit, the other satellites will operate at about 530 km height sun-synchronous orbit.

The launch will carry total of 20 satellites, there are other three satellites named as CAS-3G, CAS-3H and CAS-3I involved in amateur radio from other agencies of China will share the same launch, CAMSAT was assisting Chinese government administration to coordinate and allocate their frequencies, more details will be announced later.
