Space Edge Computer

Spiral Blue has developed the Space Edge Computer - an onboard computing system that will give Earth observation satellites the ability to process captured images on the satellite itself.

This has the potential to increase the capacity of Earth observation satellites carrying Space Edge Computers by as much as 20x.

Space Edge Computers use the NVIDIA Jetson series modules, maximising processing power while keeping power draw manageable.

There are two variants of the Space Edge computer, the SE-Z and SE-1, both of which have flight heritage.
