Abstract:  Astronomical observation satellite operates dynamic-exploration attitude maneuver mode to detect the cosmos rays. To effectively achieve the ground verification of the dynamic-exploration attitude maneuver mode, a systemlevel maneuver integration test scheme was designed. The dynamic model based on inertial space was designed to simulate the scanning process. The time unification system was developed to provide a highly precise uniform time base for subsystems. Based on the interface of STK and Matlab software, the visual interpretation system driven by telemetry data was constructed to improve the real-time and accuracy of data interpretation. The system-level test results show that the designed scheme can verify the correctness of function and the validity of performance index, which provides ideas for ground test and onorbit application.
