Abstract: A testing system is proposed towards new conditions for both ground and onorbit test. The system has been implied in a satellite and has done a good job in test. Ground testing system consists of dynamical simulator of satellite & robots, onboard module simulators, ATS and 3D display system. The system can verify logic in onboard computer and behavior of electric interface. Onorbit testing system is supplemented by the threedimensional obstacle avoidance system and the image analysis system, which works in real time with high visualization.
