船载星敏感器安装矩阵动态标定方法

为简化船载星敏感器安装矩阵标定步骤，提高星敏感器安装矩阵标定精度，提出了一种根据星敏感器测量信息和惯导系统输出信息对星敏感器安装矩阵进行动态标定的方法，将星敏感器安装矩阵的标定过程分解为粗标定和精标定两步。粗标定过程不考虑蒙气差影响，精标定过程根据粗安装矩阵和蒙气差修正模型对星敏感器测量信息进行修正，消除蒙气差影响，实现船载星敏感器安装矩阵的精确动态标定。实验结果表明，该方法经过两次迭代即可得到精确标定结果，不同时段实验结果表明该方法的一致性较好，星敏感器利用安装矩阵标定结果解算的船体姿态数据与惯导数据对比结果表明该方法是正确的。

Abstract

In order to simplify the process and improve the accuracy of ship-borne star sensor install matrix calibration, a dynamic method which uses star sensor information and INS information to calculate install matrix is proposed. Theproposed method divides the calibration process into coarse calibration step and fine calibration step. Coarse calibration step calculates the coarse install matrix without consider the influence of atmospheric refraction. By using coarse install matrix and the atmospheric refraction compensation algorithm model, the atmospheric refraction is compensated and the accurate install matrix is calibrated in fine calibration step. Experiment results show that the proposed method can get the accurate calibration result by only two iterations and the install matrixes calibrated in different times are consistent. The contrastive results of star sensor attitude and INS attitude show the correctness of the proposed method.
