摘要
在完成光纤陀螺捷联惯导系统样机的罗经法初始对准基础上,为进一步提高初始对准的精度,建立3个光纤陀螺仪随机漂移数据的ARMA模型,采用卡尔曼滤波算法进行光纤陀螺仪随机漂移的精确估计。在三轴转台试验中分析了加入光纤陀螺随机漂移ARMA模型前后的罗经法对准精度,得出光纤陀螺ARMA模型能有效地提高初始对准的精度,验证了其在工程应用中的价值。
Before the navigation,strapdown inertial navigation system（SINS） needs for the initial alignment.Complete fiber optic gyro（FOG） SINS prptptype compass initial alignmen method,to further improve the precision of the initial alignment,the ARMA model of FOG drift date had been founded,and the Kalman filter principle had been used for accurate estimation.In three axis turntable trals analyzed initial alignment accuracy,ARMA model can improve the efficiency of the initial alignment of the precision.
