摘要
介绍重力匹配导航的基本原理,根据匹配导航的基本流程对潜艇遇到障碍物的航线进行最优分析。在匹配中要对重力仪所测得的重力异常值进行厄特缶斯改正,其中速度误差是厄特缶斯改正主要误差源,改正后对重力异常值进行分析,根据重力的异常分析,推测障碍物与潜艇航迹之间的相对位置关系,从而对惯导系统的导航状态进行修正,得到最优导航状态。
The paper describes the basic theory of the gravity aided navigation.Then the best line when the fraise is on the line which based on the gravity aided is analyzed.The Etotvos is included in the unconventionality gravity which is measured by the gravity instrument.The speed error is the main source to the Etotvos,then the unconventionality gravity which is corrected is analyzed.Based on the above analysis the distance between the periscope and the fraise can be speculated,then the inertia navigation will be ameliorated and choosed the best line.
