基于双星敏感器光轴夹角在惯性空间保持不变的特性, 探讨了利用在轨测量数据, 分析星敏感器测量误差、安装参数误差及卫星结构变形的方法, 给出了相应的数学模型。通过实际计算, 验证了方法的可行性。

Based on the unchangeable characteristic of the star sensor axis angle in the inertial space, the method of star sensor measurement error, error of satellite structure installation parameters and structural deformation is discussed using the on-orbit measurement data, then the corresponding mathematical models are given out. Also the feasibility of the method is verifi e by practical calculation.
