In order to solve the problem of large time delay and low accuracy of position determination when the long-baseline positioning system is operating at large depths, the underwater acoustic positioning technology of the long-baseline array is studied and the long-baseline synchronization positioning error analysis is carried out, and the simulation verification is carried out by MATLAB. A method for optimizing the underwater acoustic positioning algorithm is proposed. After optimizing the positioning algorithm, in the case of a water depth of 6000 M and a positioning area of 1000*1000m 2 , the total positioning error of the sitting-bottom long baseline is reduced from the meter level to the decimeter level, and the positioning accuracy is greatly improved. An improved synchronous response type is determined The underwater acoustic positioning can realize the underwater large-scale, high-precision and high-real-time positioning.
