Design and Simulation of Test Route for Underwater Vehicle

The navigation accuracy test of underwater vehicles is closely related to test route design. To design optimal test route and get real navigation accuracy, this paper simulates the navigation system to get its accuracy in linear route, open-annular route, and annular route tests, respectively. Simulation result shows that the navigation accuracy in annular route test is lower than the real value due to error counteraction, while the navigation accuracy in linear route test gets closer to the real value. This paper offers a new test route design method by using simulation for underwater vehicle test.
