Abstract

The positioning error of the navigational underwater acoustic positioning method is mainly limited by the GNSS measurement error, transducer position deviation, time delay difference and sound velocity error. In view of these problems, this paper uses the method of inter-epochal difference to weaken or eliminate the systematic error, and compares and analyzes the positioning accuracy of the underwater non-differential model and the underwater differential model through the navigation underwater positioning experiment. The experimental results show that the accuracy of the underwater differential positioning algorithm is higher than that of the non-differential underwater positioning algorithm in the horizontal and vertical directions, which can reduce the proportion of systematic error in positioning error to a certain extent.
