【摘要】 根据 H调制陀螺监控惯性导航系统 (GMINS)、电子海图 (ENC)以及测深测潜仪 (BM)的不同特点 ,提出了一种 H M GMINS/ENC/BM组合导航系统。该组合系统是一种完全自主式导航系统 ,不需任何外部信息 ,在水下即可完成对惯导的校正和对导航陀螺漂移的补偿。同时还针对该组合导航系统提出了一种优化组合算法。理论分析和仿真结果表明 :采用该优化算法后 ,潜艇的重调周期可延长到 1 2 0 h。更多还原

【Abstract】 Based on the different features of HModulated gyro monitor inertial navigation system(GMINS),electric navigation chart(ENC) and bathometer(BM),this paper presents an integrated HMGMINS/ENC/BM navigation system.It is completely autonomous and doesn’t need any outer information.It can compensate the gyro drift and correct the INS without coming to the surface.The paper also presents an optimal combined algorithm for this integrated system.Theoretical analysis and simulation results show that the reset cycle of submarines can extend to 120 hours using this algorithm.更多还原
