It is essentially important for on-orbit computers to perform high-level tolerance for anomalies and high calculation performance. Redundant structure using low cost processors is an effective strategy to achieve high reliability in low cost, but it enlarge system size and weight, and is less efficient. It is also difficult to achieve high calculation performance . In order to make a system redundant efficiently, it divided into the fatal portion and the portion whose performance is more important than reliability. The system was divided by class, the portion which needs reliability was made redundant, and the portion which needs performance was made simple composition. As a result, high reliability and high efficiency are realizable in low cost and small size. In this paper, the status of development for the actual proof of UNITEC-1 is introduced about OBC which realizes high reliability and high efficiency in low cost and small size.
