【Abstract】 With the development of small satellite, housekeeping software is becoming more and more complex. To meet the requirement of automatic flying and management of small statellite, the main functions, architecture and the design of a certain small satellite are introduced. The principle of housekeeping software design, multi-task design, data communication, double computer fault diagnosing and processing are described in detail. Based on the powerful multi-task embedded operating system, the onboard computer management, attitude management, data communication and fault tolerance system are integrated designed. Thew reliability is improved and the difficiult of automatic flying and management of small satellite is solved.更多还原
