在轨服务卫星GNC系统地面测试与在轨支持设计

针对在轨服务卫星GNC系统的任务特性，设计了一套地面测试系统，经过相应模块扩展即可用于在轨服务技术支持.该系统已应用于某型号GNC系统的地面测试和在轨运行，稳定性和可靠性良好.地面测试系统由动力学仿真器、星上产品模拟器、ATS测试系统、三维显示系统组成，该系统充分验证了星上软件算法逻辑和硬件电气接口.增加三维避障、图像显示分析等模块后，测试系统实时性更强，可视化程度更高，能适应卫星在轨服务等复杂工况.

Ground Testing and On Orbit Technical Support Design forGNC System in On Orbit Service Satellites

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.
