About
The constellation On Board Computer (cOBC) is a complete subsystem entirely based on commercial components to enable high performance and short lead times at an affordable price, still delivering the high reliability Beyond Gravity is well known for. The constellation On Board Computer (cOBC) provides a host of functions including on-board processing, GNSS receiver, ground communication and both platform and payload interfaces.
The computer is fully redundant and offers flight proven fault detection, isolation, and recovery (FDIR) as well as radiation mitigation to provide a highly reliable solution.
The cOBC can be extended with dedicated I/O boards: the PDIO board offers common analogue interfaces to support magnetorquers, analogue acquisitions, thermistors, secondary power supplies, and stepper motors including SADE; the PROPE board offers the capabilities to interact with a chemical propulsion system.
