Application Prospect of Acoustic Navigation and Positioning Technology for Underwater PNT System

Acoustic navigation technology is an important part of the underwater PNT (Position, Navigation and Timing) system and an effective incremental method for the underwater PNT system construction with the concealment and the accuracy of the medium and high frequency acoustic navigation technology, and the wide-area of the low frequency acoustic navigation technology, acoustic navigation can meet the requirements of underwater users for concealment, wide-area and accuracy of underwater navigation and positioning capabilities, promoting the services ability of underwater navigation and positioning continuously. Based on the underwater application requirements, the task profile, the boundary conditions and the fusion mode are studied in this paper. Then, the advantages and limitations for underwater applications are clarified. Finally, suggestions are put forward for the future underwater application of acoustic navigation technology in China.
