Based on OneWeb satellite bus chassis, a 500 sat constellation for 24/7 full earth video surveillance at lower resolution, plus assorted higher resolution spot imagers. Bill Gates, Masayoshi Son, and Airbus are investors.

Notable as this is not a OneWeb secondary payload based constellation, and apparently they plan on using earth trained machine learning models (periodically?) uploaded to the sats to perform preprocessing onboard to reduce data download size. Which suggests they don't want to download full resolution imagery/video all the time.

The realtime claim is a bit fishy, and one wonders what the actual real tasking time is for the high rez spot imagers.

I guess Airbus is doing investment plus some bartering for equity in exchange for OneWeb bus manufacturing line access?

To make this a proper Advanced Concepts thread, how severe is the design constraints for running machine learning models on imagery in-situ prior to downlink?

You depending on how things are done on the neural network/machine learning front, you will need a fairly substantial CPU/GPU setup with associated heat/power requirements. Being in space, high computational power rad hardened GPU's are not yet a thing. Would you go FPGA instead? How much redundancy?

In terms of bus basis, will they be actively exploiting inter-satellite links to transfer data?

Why is this in the Advanced Concepts section? This is already being discussed in the OneWeb thread.
