| 摘 要： | 针对实际捷联惯性导航系统解算中的圆锥误差和划桨误差,结合已解算出的当前时刻之前两个周期的姿态信息对旋转矢量进行修正的算法,利用算法的对偶性原理,将该算法应用于划桨误差补偿算法中。在划桨运动下对该算法进行了仿真,仿真结果表明,该划桨误差补偿算法具有与解析解相当的精度。

| Abstract: | In a real Strap-down Inertial Navigation System (SINS), there exist coning error and sculling error. The coning error for attitude determination and sculling error for velocity updating are introduced when there are angle vibration and line vibration to the mobiles. A high accuracy algorithm for the sculling error compensation is proposed with the generic equivalency. The accuracy of the proposed algorithm is confirmed by simulation. |
