摘要: 介绍星敏感器的误差分类、低频误差定义、误差产生原因及其测试标定方法等.星敏感器输出姿态周期性误差的主要原因为视场空间误差和热弹性变形误差,典型星敏感器采取相应的解决措施后,低频误差可控制在0.8″以内.

关键词: 星敏感器, 误差分析, 低频误差, 控制措施

Abstract: The error resources of star sensor, definition of low frequency error (LFE), error analysis and calibration methods are described in this paper. The field of view (FOV) spatial error and thermo elastic error are the main factors in orbital periodic error of star sensor. The LFE of typical star sensor is less than 0.8″ via new methods.

Key words: star sensor, error analysis, low frequency error, calibration method
