Research on the architecture and key technologies of intelligent navigation service

As one of the five elements of intelligent shipping, intelligent navigation service is an essential link of shipping digital transformation. It is necessary to build standardized navigation service infrastructure and information service system to adapt to the needs of intelligent dynamic control of maritime transportation. By analyzing the development status quo of intelligent navigation service at home and abroad, this paper puts forward the system architecture of intelligent navigation service from the aspects of data center, service platform and scenario application; then, this paper discusses the key technologies of intelligent navigation, including 6 basic technologies and 3 prospective technologies; taking intelligent maritime supervision and intelligent port service as cases, this paper analyzes the typical service mode and role of intelligent navigation service. The results show that intelligent navigation service is a development system of digital and intelligent transformation of navigation service oriented by application demand and based on data. This research can provide technical support for the construction of intelligent navigation service in China.
