The visual simulation architecture of space scene is very important in managing, analyzing and displaying the space objects. With the knowledge of computer graphics, astronomy, mathematics, and kinematics etc. A platform of space scene, which mainly focuses the earth, is developed. In addition, a visual simulation system of satellite motion in orbit based on the platform is also developed. This paper describes the design and the implementation of the platform and the visual simulation system. Some key technologies are involved, such as overlay area modeling, geometry modeling and kinematics modeling, communication special effect modeling and distributed displaying. The simulation results show that the visual effect is vivid and realistic, and can meet the requirement of real time visual system.
