星敏感器的姿态测量精度是评价星敏感器性能以及卫星姿态确定的最重要指标之一。本文提出一种星敏感器的测量误差分析方法, 适用于卫星在轨运行期间以及整星地面测试阶段星敏感器测量误差的确定, 特别是在目标姿态无法准确预知情况下的误差确定。

Attitude accuracy is one of the most important parameters to evaluate the performance of the star trackers. In this paper, a method of star tracker measurement errors is presented.This method is applicable to the in-orbit and on-ground analysis of measurement errors. Especially on uncertain attitude of the analysis.
