Abstract: To improve navigation accuracy of long-endurance unmanned undersea vehicle(UUV) and to standardize the navigation performance evaluation specifications, a navigation calibration and performance evaluation method of long- endurance UUV is proposed. Firstly, the common navigation methods of UUV are summarized, and navigation test requirements of long-endurance UUV are provided. Then the process of the navigation calibration and performance evaluation is put forward, the performance evaluation specifications are given, and some suggestions for the method are offered. Finally, the underwater transponder positioning (UTP) is used as an auxiliary navigation equipment to correct the UUV navigation results. Simulation results show that the proposed method can effectively suppress the cumulative error of long-endurance UUV navigation. This method may provide a reference for improving the accuracy of long-endurance UUV navigation. -
