ALGORITHM REALIZATION AND SIMULATION ANALYSIS OF GRAVITY ANOMALY AIDED NAVIGATION
重力异常匹配导航的算法实现与仿真分析

In order to meet the requirement of passivity of the underwater navigation,the gravity anomaly aided inertial navigation system has been used to implement the autonomous underwater navigation.The algorithm has been simulated by use of a simulation tool Simulink.The results indicate that the gravity anomaly aided navigation can be used to get fairly high precision in the areas with relatively large gravity anomaly variation,and therefore reducing the error of the inertial navigation system.
