天文观测卫星动中探测机动测试系统设计

天文观测卫星普遍采用动中探测模式开展空间探测任务。为了实现动中探测姿态机动模式的地面有效验证，设计了整星机动集成测试方案。设计惯性空间基准的地面动力学仿真，满足惯性空间扫描仿真；设计整星各分系统间高精度时间统一系统，为整星机动测试提供统一基准；基于STK与Matlab接口模块，设计基于实时遥测数据的可视化判读系统，可提高测试判读实时性与准确度。整星测试结果表明，该方案有效验证了动中探测任务中姿态机动功能的正确性和指标符合情况，为开展整星地面测试和在轨应用提供了参考。

Design of dynamic-exploration maneuver test system for astronomical observation satellite

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.
