摘要
结合工程实际应用,充分考虑激光陀螺捷联惯导系统的特性,重点分析了三种与系统动态运动相关的误差,包括尺寸效应误差、圆锥误差以及划船误差。从工程应用的角度出发,分别推导了尺寸效应误差补偿算法、圆锥误差补偿递推算法和划船误差补偿递推算法,并进行了大量的试验,对补偿效果进行了充分地验证。实验结果表明,补偿算法不增加导航计算机的负担,保证了系统在高动态条件下的精度,可以充分发挥激光陀螺的优势,提高激光陀螺捷联惯导系统的导航精度。
Combining with the engineering practical application, and considering the characteristic of RLG SINS, including dimension effect error, coning error and sculling error, three kinds of kinematics error are analyzed in detail. From the engineering viewpoint, the dimension effect error compensation algorithm, the coning error compensation recursion algorithm and the sculling error compensation recursion algorithm are deduced respectively. Compensation effect is validated by doing a lot of experiments. The experiment results show that the compensation algorithms don＇t increase CPU＇s burden and can guarantee the system accuracy under the condition of high dynamic motion, so they can take full advantages of RLG, thus increase RLG SINS＇s navigation accuracy.
