对基于弹载IMU/GPS组合导航系统的动基座对准问题进行了研究与仿真;首先,分析了弹载IMU与GPS的系统误差,建立获得了其系统误差模型;然后,利用卡尔曼滤波技术,设计了弹载IMU/GPS组合导航系统的动基座对准算法;仿真结果表明,在初始误差较大的情况下,经过360秒的动基座对准,IMU的姿态角误差可降至10个角秒,同时位置和速度误差也得到了有效修正,从而证明该动基座对准算法是行之有效的。

补充资料:因水火风动故地动
【因水火风动故地动】
  经云:此阎浮提地,南北阔二万一千由旬,东西阔七千由旬,厚六万八千由旬。地下有水,厚八万四千由旬。水下有火,厚八万四千由旬。火下有风,厚六万八千由旬。风下有金刚轮,过去诸佛舍利,咸在其中。或有时大风忽动,火亦随动。火既动已,水复随动。水既动已,地即随动。故云因水火风动故地动。(梵语阎浮提,华言胜金洲。梵语由旬,华言限量,或四十里,或六十、八十里也。)
