提出了一种基于星光/惯性平台系统中星敏感器安装误差的地面标定方法,利用高精度的星模拟器,模拟远处恒星,将星敏感器主光轴对准星光,通过测量恒星与平台台体六面体的位置坐标,经过坐标转换后,对比得到星敏感器在惯性平台中的安装误差。实验数据表明,该方法可准确测量出星敏感器在星光/惯性平台中的安装误差角,实现误差的精确标定。
A ground calibration method based on the installation error of the star sensor in the star / inertial platform system is proposed. By using a high-precision star simulator and simulating a distant star, the main optical axis of the star sensor is aligned with the starlight. By measuring the position of the star and the platform Taiwan body hexahedral position coordinates, after coordinate conversion, the star sensor to be compared in inertial platform installation error. The experimental data show that this method can accurately measure the installation error angle of the star sensor in the star / inertial platform, and realize the accurate calibration of the error.
