I have been curious about this service for a while but the landing page is very scant on technical details about how it actually works. - Is it an EC2 instance with an SDR attached? What’s the software setup? Is it compatible with GNUradio? - What are the the antenna RX gain(s)? - What TX power can be used? Edit: I found this presentation [1] which has some additional details. It does seem to be SDR based but I can’t find public information about many of the parts/interfaces in the architecture diagrams. Edit 2: There are a few more breadcrumbs of information on the AWS documentation site [2]. It sounds like the EC2 instance receives VITA-49 (?) packets from the RF front end and you need special software to process them. [1] https://d1.awsstatic.com/events/reinvent/2019/REPEAT_1_Enabl...

All other solutions for streaming the data seem vendor specific to their hardware and software.
When AWS Ground Station launched I looked into their terms of service, hoping to be able to rent some time on their big dish to receive images from weather satellites. But no, you needed to own the satellite in question, not just have the keplerian elements for pointing at it and then demodulating the unencrypted, freely broadcast images from it. But no. Gota own the sat.
I wonder if that has changed.
But I can understand why. It's not like you want to run a SIGINT-As-A-Service platform that everybody with a credit card and maybe a Delaware corparation can use.
