Overview
The OBC is a flight-proven, high-reliability onboard computer (OBC) designed for low Earth orbit microsatellites. It conforms to the Eurocard 3U form factor and includes standard interfaces essential for most satellite sensors and actuators. With substantial processing power and memory, it can run a complete satellite software suite, including high-fidelity AOCS with FDIR. The OBC can operate independently or as part of a redundant pair for enhanced reliability. It also includes an independent microcontroller dedicated to magnetic control, capable of performing satellite detumbling and basic AOCS operations.
