THE FAULT-TOLERANT DESIGN FOR MICRO-SATELLITE ON-BOARD COMPUTER SOFTWARE

摘要

The thesis introduces the software design of satellite computer for Chuangxin-1 micro-satellite, including OBDH software, telecommand and telemetry software, power control software. The satellite computer adopted Hardware and Software Co-design to achieve fault-tolerant, some functions which only implemented by hardware are carried out by software now, and some fault-tolerant technology which handled with space environment achieved by software too. The satellite computer software adopted some new technology which applied first in china, after one year's normal running, the reliability was proved.
