On-board computer system for KITSAT-the first Korean satellite

In this paper an on-board computer system for the first Korean satellite, KITSAT is presented. The design technologies for large commercial satellites cannot be directly used for the microsatellite due to the compactness. The design drivers and decisions made in the development of the KITSAT on-board computer system are described to fulfil the microsatellite design constraints. The features of on-board computer hardware and operating system are presented. The in-orbit performance of a mission control computer (MCC) is also discussed with the memory subsystem error log and the attitude control subsystem results.<
