Focusing on these problems,this paper proposed a new alignment scheme with Kalman filter which considers velocity error,attitude error and azimuth error as observed quantity.
针对低成本捷联惯导系统难以完成航向自对准以及静基座对准可观性和可观度低的问题,提出了同时将速度误差、姿态误差和航向误差作为观测量的卡尔曼滤波对准方案;建立了姿态误差、航向误差与数学平台误差角之间的量测关系;推导了利用加速度计计算姿态的方法,并配置磁传感器作为外观测设备提供航向参考基准,从而获得滤波器观测量。
