| 摘 要： | 为了获得优于0.1n mile/h水平的高精度激光陀螺惯导系统,对控制系统绕单轴转动来补偿陀螺误差的方法进行了研究。分析了补偿的原理,并利用通用的精度为0.4n mile/h左右的机抖激光陀螺捷联惯导系统进行了实物实验,实验结果证明采用单轴转动的方法可使系统定位精度提高到1n mile/24h的水平。

| Abstract: | To get RLG(Ring Laser Gyro) INS(Inertial Navigation System) with accuracy better than 0.1 n mile/h,a method of rotating the system around a single axis is discussed.By the rotation some RLG errors can be compensated automatically.The principle of the compensation is described,and a normal strapdown RLG system of 0.4 n mile/h is rotated to check the principle.The results show that the system can achieve about 1n mile/24h with rotation. |
