Research on web-based ship navigation system

According to the convenient condition of wireless Internet service along inland rivers in China, the paper researched a web-based ship navigation system for inland river navigation. The system is developed with three-tier network architecture, and runs on web browsers. Based on an electronic channel chart platform developed by COM and JSP, the system provides comprehensive navigation service for ship users, including channel chart display, information query, position, navigation alarm and so on. Furthermore, it can collect the dynamic information of all ships within the system for ship owners, ports, VTS centers, maritime authorities and other administrative department to monitor and manage ships. It is expected to play an important role in enhancing ship´s navigation safety and improving transport efficiency of inland river shipping in China.
