For INS/DVL integrated navigation system in a long-distance underwater vehicle,the scheme of Kalman filtering based on the pre-compensation of velocity measurement deviation generated by DVL is proposed. The methods and measures of pre-compensation of the velocity measurement deviation are introduced. The test validation result shows that the integrated navi-gation technology based on pre-compensation of the velocity measurement deviation caused by DVL can improve the filtering con-vergence features and the navigation accuracy of the system.
