The On-Board Computer (OBC) hardware is the central processing unit of the YPSat, interconnecting all subsystems and payload components. The OBC hardware is encased within an aluminium box to shield from ionizing radiation and to ensure electromagnetic compatibility. Its software relies on a real-time operating system to facilitate memory management, telemetry functions, and task scheduling. Additionally, the software incorporates a watchdog timer to synchronise the coordination among the various subsystems and payloads throughout the mission phases, including power-up, recording, data transfer, and downlink transmission.
