%X 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.
