摘要
研究了对船用捷联惯性导航系统(SINS)的初始对准问题,在船舶晃动的情况下,可采用鲁棒状态估计器对失准角进行估计,并利用状态估值对系统的误差进行补偿,仿真结果证明了新型滤波器对于克服船舶晃动干扰具有良好效果.
The initial alignment of ship SINS is investigated.A robust state estimator is proposed which achieves good results even when the ship is disturbed by winds and sea waves.The simulation results have proved its good performence in reaching high attitude accuracy.
