Abstract

Abstract: This thesis introduces the OBC(on-board-computer)of CX-1 micro-satellite, being the first micro-satellite of China under 100 kilogram, the OBC of CX-1 adopts some new fault-tolerant technologies, which improve the reliability of the micro-satellite. It has run normally in orbit over one year, and the reliability of the micro-satellite is verified. The OBC lives through the SEUs(Single Event Upset) many times and still does good job by now. The thesis shows the main characters and the design blueprint of the OBC. The main technology of reliability of the OBC is also projected.

Key words: Satellite, On-board-computer, Hardware, Software
