About
DSI’s On-board Computers provide robust central computing to control all aspects of a spacecraft, from telemetry monitoring to subsystem control. These solutions can be hot dual redundant, allowing for extremely high reliability for the most critical part of the spacecraft avionics. Key features include fault detection, spacecraft monitoring and control, time management, EDAC protected memories, HK and TM provision, and spacecraft command execution, all within a single point failure-free design. DSI OBCs are highly flexible and can be outfitted with a wide range of interfaces and features, including memory functions if required. They are available as a fully independent unit in an enclosure, ready for integration, or as a board-level product to be integrated into existing enclosures.
