磁场信号检测误差分析及补偿算法
|
摘要
针对载体自身磁场特性及三轴磁传感器误差特性建立了地磁导航干扰误差补偿模型,通过对模型进行简化变形,利用系统辨识的最小二乘估计算法(LS)求取误差特性参数。数据分析表明:该方法简单易实现,简化了复杂的求解过程,基本达到了误差补偿的要求。
The article aiming at the carrier's own magnetic field characteristics and the error characteristics of three-axis magnetic sensor establishes geomagnetic navigation interference error compensation model.Though simplify the deformation,it uses least squares estimation algorithm of system identification model to strike algorithm error parameters.Data analysis show:the method is simple and easy to implement,to simplify the processing of complexity solving,and mainly achieving the error compensation requirements.
