Abstract:With the gradual in-depth development of the ocean, the demand for underwater multi-platform operation is becoming more and more significant, and the mutual position relationship between platforms is an important information to ensure the efficiency of the operation. Therefore, this paper analyzes the position measurement method based on acoustic ultra-short baseline positioning technology, analyzes the acoustic propagation characteristics, positioning working principle, error sources and main error models, and analyzes the positioning accuracy and distance by means of historical environmental parameters and simulation analysis. On this basis, based on the typical application scenarios of underwater operations, the optimal co-positioning strategy is given after analysis at different reception and emission depths, which is helpful to guide underwater cooperative operations.
