摘要：
With the emergence of an intelligent era marked by the interconnection of all things, mutually empowering communication and navigation and creating a ubiquitous network that merges communication and navigation are imperative. Encountered with the separate development of underwater communication and navigation systems, this paper presents a review of the development of these two technologies, demonstrating that underwater acoustic communication is the primary method for long-distance underwater communication, even though its performance is weaker than that of terrestrial wireless communication. Underwater optical and electromagnetic wave communications can offer stable short-range communication services. The underwater acoustic navigation technology is the most widely used underwater navigation technology. Foreign commercial businesses have produced a series of products, while domestic ones have accomplished “keeping up” in key technical indicators. Presently, China, the United States, Japan, and other countries/ regions are intensifying their research on marine integrated communication and navigation systems and have realized networking results in shallow waters, centimeter-level precision with seafloor geodesy, meter-level precision navigation in local waters, and kilometer-level precision positioning in medium-scale waters. However, a fully developed marine integrated communication and navigation system has not yet been developed. © 2023 Editorial Board of Journal of Harbin Engineering. All rights reserved.
