星敏感器外场观星标定及检验方法研究

摘要

The mainly calibration methods of the star sensor,which is based on the real space experiment outfield,as well as the composition and structure of the test platform,were introduced. The dynamic and static three-axis attitude accuracy and the update rate of output data were acquired by processing and analyzing the related experiment data obtained from the dual-CCD star sensor. The results showed that the calibration method on real space can examine the performance specifications on accuracy,update rate,sensitive magnitude and capture time of the star sensor,and have high credibility.%介绍了星敏感器的主要检验标定方法—外场实测观星标定方法，以及实验平台的组成和搭建。根据对双 CCD 探头星敏感器获取的实验数据进行处理、分析，给出了动、静态三轴姿态精度和数据更新率。实验结果表明，采用这种方法可对星敏感器的精度、更新率、敏感星等级、捕获时间等指标进行检验，可信度高。
