Cool post. I'd be interested in seeing models likes this deployed to the satellites themselves.

Typically, data gathered from satellites needs to wait for the satellite to do a pass over a dedicated ground station before it can be processed, which is probably somewhere in the US. If you move the processing from the ground station to the satellite, then you 1. Don't have to transmit as much data, 2. Can transmit actionable intelligence much faster. It can be upwards of 90 minutes before a satellite passes over it's ground station. If you could get that down to a few seconds, I could see some serious applications in disaster response.

From discussions I've seen online, a lot can fail on satellites so there is a bias to do as little as possible on them. There does appear to be plenty of bandwidth to transmit back to ground stations.

The real win will be satellite-to-satellite transmissions where any data collected by the constellation is passed to the satellite that'll next fly over a ground station. This will lower the time from capture to analysis considerably. The fresher the data, the more valuable it is.
