创新一号小卫星星载计算机控制系统设计

Design of On-board-computer Control System for CX-1 Micro-satellite

对创新一号小卫星的星载计算机系统的设计进行了介绍,作为我国第一颗重量在100kg以下的小卫星,创新一号星载计算机采用了多项国内首次使用的新技术,经过一年的飞行测试验证,证明了卫星计算机系统的安全可靠,该文就星载计算机系统的主要特点和采用的可靠性设计技术进行了较深入的研究,反映了创新一号星载计算机系统所获得的主要成绩。

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.
