摘要
为了更好的对三轴地磁传感器的偏置误差、比例系数误差以及非正交误差参数校准求解,文中在原有误差校准算法基础上,组合姿态相关和姿态无关的校准算法,设计出了一种新型旋转卡尔曼滤波器。该滤波器是一种关于三轴地磁传感器误差参数的逐步校准算法。它特别适用于旋转稳定的火箭弹;最后通过仿真计算,得出该算法可以准确的对三轴磁传感器的误差参数校准求解。
In order to get a good solution to biases, scale factor errors and non-orthogonal misalignment of three-axis magnetometer, a new spinning spacecraft Kalman filter was designed. It combines attitude-independent and attitude-dependent calibration algorithms on the basis of original error calibration algorithm . The new Kalman filter is an iterative calibration algorithm on error parameters of three-axis magne- tometer calibration. It is particularly well-suited to spin-stabilized spacecraft. Finally, through simulation, the error parameters of three-ax- is magnetometer were accurately solved.
