摘　　要：多星模拟器是一种能够在实验室内模拟天空中多颗恒星位置、星等、光谱信息的装置,用于完成星敏感器的室内测试和标定。针对星敏感器设备试验需求,描述了组成固定分布式多星模拟器的单星模拟器和支架的设计,以及检验多星模拟器模拟星点角位置稳定性、平移造成的模拟星角位置误差等采用的检测仪器和方法。检测结果模拟星点角位置,实际检测数据证明各项性能指标均达到了设计要求,可用于星敏感器的室内动静态性能测试试验,有效缩短星敏感器试验和测试时间。Multi-star simulator is a device that can simulate the position,magnitude and spectral information of multiple stars in the sky in a test chamber,used to complete indoor testing and calibration of star sensors.The design of the single star simulator and bracket that form a fixed distributed multi-star simulator for the test requirements of the star sensor equipment is described in detail in the article,as well as the detection instruments and methods used to test the stability of the simulated star angle position of the multi-star simulator and the error of the simulated star angle position caused by translation.The test results show that the performance indicators of the multi-star simulator meet the design requirements and can be used for indoor dynamic and static performance test of the star sensor.
