摘　　要：为了解决空间光电跟瞄系统在真空环境下的多光轴标校问题,本文首先根据空间光电跟瞄系统的多光轴一致性检测精度要求,设计了一套多光轴标校系统。接着,对多光轴标校系统各子系统进行了详尽的误差分析,并给出了关键子系统的误差影响抑制方法。然后,对通信技术试验卫星三号的空间光电跟瞄系统进行了实验室环境与真空环境下的技术测试,分析了多光轴标校系统在两种测试环境下的误差来源以及测试精度,并给出了测试结果。最后,对多光轴标校系统进行了精度验证。最终结果表明:本文设计的多光轴标校系统在实验室测试环境下的标校精度为0.998″,收发平行度标定误差为1.165″;在真空测试环境下的标校精度为1.219″,收发平行度标定误差为1.359″,完全满足空间光电跟瞄系统1.5″的多光轴检测精度要求,为相关工程应用提供了技术支持。To achieve multi-optical axis calibration of the space photoelectric tracking and aiming system in a vacuum,this paper first designed a set of multi-axis calibration systems according to the accuracy requirements for multi-axis consistency detection of the space photoelectric tracking and aiming system.Then,a detailed error analysis of each subsystem of the multi-axis calibration system was conducted,and the methods to restrain the influence of error in the key subsystem were given.After that,the technical tests of the space photoelectric tracking and aiming system of the Communications Technology Experiment Satellite 3 were implemented in laboratory and vacuum environments,and the error sources and test accuracy of the multi-axis calibration system in the two test environments were analyzed and the test results were given.Finally,the accuracy of the multi-axis calibration system was verified.The final results show that the calibration accuracy of the multi-axis calibration system in this paper is 0.998"in the laboratory test environment,and the calibration error of the parallelism of transmitter and receiver is 1.165";the calibration accuracy is 1.219"in the vacuum test environment,and the calibration error of parallelism of transmitter and receiver is 1.359".These results fully meet the 1.5"multi-optical axis detection accuracy requirements of the space photoelectric tracking system,and provide support for research in related engineering applications.
