CAMSAT amateur radio transponder satellites to launch this year

CAMSAT has released details of three new amateur radio satellites, CAS-5A, CAS-5B and CAS-6, that are hoped to launch in September 2018. Two of the satellites CAS-5A and CAS-6 will carry transponders.

CAS-5A a 6U CubeSat which will include the following capabilities:
• HF/HF – H/T Mode Linear Transponder
• HF/UHF – H/U Mode Linear Transponder
• HF – CW Telemetry Beacon
• VHF/UHF – V/U Mode Linear Transponder
• VHF/UHF – V/U Mode FM Transponder
• UHF – CW Telemetry Beacon
• UHF – AX.25 4.8k/9.6k Baud GMSK Telemetry.
The transponders will have 30 kHz bandwidths except the H/U one which will be 15 kHz. Planning a launch in September 2018 from the Jiuquan Satellite Launch Center into a 539×533 km 97.5 degree orbit.

CAS-5B a femto-satellite architecture 90Lx80Wx50H mm with a mass of 0.5kg Proposing a UHF CW beacon and to be deployed from CAS-5A when in space.

CAS-6 a 50 kg micro satellite approx 490 x 499 x 430 mm. It will include:
• VHF CW Telemetry Beacon
• U/V Mode 20 kHz Linear Transponder
• AX.25 4.8k baud GMSK telemetry downlink
• Deployable Antennas
• Solar Panels, Lithium ion battery and power controller
• Integrated Housekeeping Unit
• Three-axis stabilization system
• Atmospheric Wind detector
• S-band TT&C system (non-amateur radio band)
• X-band Data link system (non-amateur radio band)
Planning a Sea Launch Pad from the China Academy of Launch Vehicle Technology in September 2018 into a 579 x 579 km 45 degree orbit.

The FalconSAT-3 satellite..

 The FalconSAT-3 satellite Packet Bulletin Board System
 Packet Bulletin Board System is active .

The FalconSAT-3 satellite is in a 35.4 degree inclination orbit, with an approximate altitude of 465 to 476 km. The Packet Bulletin Board System is operating at 9600 baud with a 145.840 uplink, and 435.103 downlink. Output power is 1 watt, and the downlink is continuously on. Current Keplerian elements can be found in the AMSAT distributed Keplerian elements. More information can be found at https://www.amsat.org/falconsat-3/
