摘　　要：提出了一种适用于高精度光纤陀螺的静态输出信号建模的时间序列模型,建立了光纤陀螺随机误差的卡尔曼滤波器。结果表明,该建模和滤波方法有效地减小了FOG的误差,明显地降低了陀螺的随机漂移,提高了导航精度,具有较好的实用价值。A time sequence model which can be applied in the modeling of high-precise FOG′s static output signal is presented,and the real time Kalman filter of FOG random error is built.The result shows that this modeling and filtering method can reduce the error of high-precise FOG.The navigation errors are depressed,and the navigation precision is improved.
