Abstract: The software on small satellite is becoming more complicated and needs the support of Operating System(OS). This paper describes what kind of OS satellite software required and presents a micro kernel structure for satellite embedded system with the characteristics of satellite application oriented, small size, software reconfigurable, high real-time and stability.

Key words: satellite software, Operating System(OS), micro kernel, inpouring code on the orbit
