摘要
原有的太阳敏感器采用多项式拟合进行误差补偿,标定精度较低.通过建模精确分析新型太阳敏感器各误差源的影响,提出一种新型误差标定方法,用于补偿太阳敏感器的几何误差,并给出了误差补偿方法.实验结果表明:该方法比标定前精度提高3倍以上.
Polynomial fitting method is usually used to compensate the error of sun sensors,and the calibration precision is relatively low. According to the modeling analysis of the influence of various error sources,a new calibration method is proposed,and an error compensation method is provided to compensate the geometric error. The experimental results show that the calibration accuracy is over 3 times higher than the ordinary one.
