摘要： 根据中、小型潜艇的实际航行特点,利用最小二乘递推估计方法,设计了一种简单可行的INS误差估计方法.理论分析和仿真结果表明,通过合理选择采样周期,该方法能很好地估计出INS系统的速度误差和计程仪速度误差.最后,本文还对该方法的实用性进行了分析,为在潜艇上的实际应用奠定了基础.

Abstract: In order to ensure the output precision of long-time-working INS(inertial navigation system), it is necessary to reset the INS to ensure the safety of submarines.A simply but efficient scheme has been designed according to the characteristics of submarines underwater navigation.The analysis and simulation results show that this scheme can estimate the velocity errors of INS efficiently.Finally, the feasibility of this scheme is also analyzed.

Key words: INS, errors estimation, level damp, least-square algorithm
