Recently performance of COTS (Commercial Off-The-Shelf) parts are accomplishing remarkable development, they have been installed in a small satellite instead of space grade parts. An On-board computer unit, a Data storage unit, X-band transmitter and a Power supply unit mainly composed of COTS have been developed for the future trend of small satellite. As notable features, an error detection correction and a TMR (Triple Modular Redundancy) with LEON3 processor; are equipped to prevent influence on their performance from harsh space environment. These devices have an enough adequate performance as practical bus system in the small satellite, and they have advantage in terms of reasonable cost and lead time rather than traditional space products.
