CAMSAT’s CAS-10 is an 8U CubeSat that will carry an Amateur Radio VHF to UHF linear transponder for SSB communications.
A follow on mission from CAS-9 and also known as Hope-4 (XW-4) CAS-10 is an 8U CubeSat, approx 228 x455x 100mm, with a mass of 12kg. The satellite will carry:
1. A VHF uplink and UHF downlink linear transponder with a bandwidth of 30kHz. This transponder will work all day during the life cycle of the satellite, and amateur radio enthusiasts around the globe can use it for two-way radio relay communications.
2. A camera, and the pictures it takes are stored in the flash memory on the satellite, we have designed a simple remote control system based on DTMF, and amateur radio enthusiasts around the globe can send DTMF commands to download the camera photos.
3. A CW beacon to send satellite telemetry data, which is also a feature that is widely welcomed by amateur radio enthusiasts.
4. A AX.25 4.8k/9.6kbps GMSK telemetry downlink
Planning a launch in November 2022 from Hainan Launch Center using a CZ-7 launch vehicle into a 400km circular 42.9 degree inclination orbit.
