Aiming at the problem of solar radiation in orbit of APS star sensor, the influence of solar radiation on the function and performance of star sensor is analyzed. The experiment and verification schemes related to solar radiation are designed. Finally, the related test process and test The results of the analysis and experiment are clear.The results of analysis and experiment show that the ultraviolet radiation test has no obvious influence on the optical system transmittance and affects the sensitivity margin of the APS star sensor. Star sensor detector and the whole machine has no effect on the function and performance.Related analysis and test data can be used as the basis for future improvement of star sensor design and reference.
