【摘要】 红外地球敏感器地面标定试验的精度高低,将直接影响到卫星在轨道上的工作精度。地球模拟器是卫星姿态测量控制关键部件红外地球敏感器的一项重要地面模拟试验与精度标定设备。详细介绍了摆动扫描式红外地球敏感器整机电磁兼容性试验专用性能测试用的地球模拟器的组成和总体结构,针对用于同步和较低的轨道卫星地面测试,研究的地球模拟器针对卫星二个轨道高度35786km和21500km,采用可更换地球光阑的方案,能够提供两种地球张角(17.46°和26.54°),实现了地面上模拟卫星在太空中所看到的地球。该问题的研究对提高摆动扫描式红外地球敏感器卫星地面性能测试水平具有重要意义。更多还原

【Abstract】 Precision of the infrared earth sensor demarcation test directly affects working precision of satellite on the orbit. The earth simulator is the most important ground-based testing equipment for the infrared earth sensor, and also a key component in the satellite controlling system. The composition and collective structure of earth simulator used in the whole machine’s EMS testing of the swing scanned mode infrared earth sensor is introduced detailedly. For synchro and the lower orbit heights, the earth simulator adopts a project of replaceable earth diaphragm for two orbit heights 35 786 km and 21 500 km, and can support two earth angles (17.46°and 26.54°), resulting simulating the earth on the ground which can be seen in the space by the satellite. The research has the important meaning for improving the satellite’s ground capability testing level of the swing scanning infrared earth sensor.更多还原
