CubeSat On-Board Computer – Main Bus Unit SatBus 3C2

The minimum order quantity for this subsystem is 5 pieces.

SatBus 3C2 is a highly integrated nano-satellite main bus unit containing advanced functionality:

An on-board flight computer (OBC)
An attitude determination & control system (ADCS)
Redundant UHF communication system (COMM)

SatBus 3C2 is tailored for small-sized satellites and complies with the CubeSat standard. The system is designed to reduce customers’ time and budget costs, minimize required integration effort and effectively increase volume for payload as well as overall system reliability through matched hardware on one board.
