摘要
为实现天文导航系统位置和航向信息对惯性导航系统误差的有效修正,设计了一种远程长航时惯性/天文位置、航向组合导航总体方案,提出了天文信息辅助的惯导航向修正方法,并推导了惯性/天文位置组合导航动态方程。仿真结果表明,提出的远程长航时惯性/天文位置、航向组合导航方案和算法是正确的,且有效地提高了组合导航系统性能。
A heading correction method for inertial navigation system with the aid of celestial information was proposed and the dynamic equation of the SINS/CNS position integrated navigation system was also deduced in this paper. The simulation results show that the scheme and algorithm of SINS/CNS position and orientation integrated navigation system are correct, which can effectively improve the performance of integrated navigation system.
