摘要
针对目前星敏感器安装误差标定过程中存在的标定模型复杂标定测试流程繁琐等问题,提出了一种星敏感器安装误差的三位置法地面标定方法。该方法根据坐标系的欧拉变换,构建了星敏感器安装误差的数学模型;根据误差模型,提出了基于三轴精密转台的安装误差三位置法地面标定策略。采用最小二乘法和三位置法进行仿真对比实验,结果表明,安装误差的三位置法标定结果比最小二乘法标定结果的稳定性提高了近10倍。三位置法还具有标定测试流程简单等优点,对提高星敏感器的使用精度具有重要参考价值。
Aiming at problems such as complicated calibration models and trivial test progress, which are occurred during the calibration of installation error for star sensors, a novel ground calibration method of installation error based on three positions was introduced. Firstly, a mathematical model of installation error was established according to Euler transformation of coordinate systems. Secondly, a new ground calibration strategy of installation error based on three typically-selected positions on a triaxial precise turntable was put forward. The least square method and three positions method were adopted to conduct simulation contrast experiments. Simulation results demonstrate that calibration result stability of three positions method increases by nearly 10 times than calibration result stability of least square method. Furthermore, three positions method has simplified the calibration test procedure, which has important practical reference value to improve the operational accuracy of star sensor.
