[Ground-station] Please vote - Ambasat sensor

[Douglas Quagliana]

Rather than a sensor, could we get an ulta stable oscillator (USO) for some frequency in an amateur satellite band? We would just need the USO, a small amplifier and an antenna. Even an inefficient antenna. Even if we’re only radiating a few milliwatts. There’s still a lot of good science we can do from an unmodulated carrier with Doppler. 

Regards,
Douglas

The chirp spread spectrum modulation handles doppler quite well and LoRA chips on carrier boards are easy to find to make ground stations.  Unfortunately there is little chance we could license it since the FCC decided that anything smaller than a 1U cubesat is too small to track.

>>> I asked Ambasat about a custom amateur radio payload, so we could test something for us. The kickstarter had that option. The lead of Ambasat said yes, amateur payload ok, several people I asked at Virginia Tech said go for it, and a small group looked at the specs and tried to design something useful for us. But, the very compact size and power budget was quite daunting. And the time frame was very short. We don’t have enough miniaturization or time. Instead of a custom board, we have a standard flight and a ground version.
