Abstract: The fault safety design is one of the key factors to ensure the GEO satellite in service with long life and high reliability. Firstly, the investigation the fault safety design of the international topranking GEO satellite is done in detail. Then the features of the fault safety design of domestic GEO satellite are described briefly, and the author’s opinions are mentioned. Finally, the suggestion and idea are proposed to improve the fault safety design of the domestic GEO satellite in future according to synthesis of the investigation and study. The suggestion and idea are expected to use for helpful reference to the fault safety design of the domestic GEO satellite, and be useful for the improvement of the reliability of the domestic GEO satellite.

Key words: fault safety design, GEO satellite
