Abstract: To satisfy the ground verification request of the ZY3 satellite’s high precision control subsystem, a whole set of verification system is designed. The system can ensure the complicated verification under the test status, including the control subsystem’s outer interface, equipmentrelated trouble check and switch, system function, implement of attitude control performance, and inorbit fault prevention plan. After the launch of ZY3 satellite, the control subsystem works stably in orbit. Moreover, the attitude control precision and the time precision both satisfy the satellite index.

Key words: ZY3 satellite, high precision, control system, testing technology
