Satellite control is considered as one of the most modern spacecraft technology. The main advantage of satellite is its ability to obtain a global look at large area of the earth's surface, therefor a system of three satellites in geosynchronous orbit can cover almost all of the earth's surface. This led to the application of satellites in several areas, such as communications by high frequency line-of -sight radio links, photography for meteorology, earth resources and navigation for aircraft and ships.This paper introduce the design and the computer simulate of the attitude control system for three axis stabilization satellite
