| In recent years, with the development of maritime transport industry development and transformation, the ship gradually toward large-scale, intelligence and the development of high speed. For a ship, large scale means that more people will pay attention to it; the ship intelligent means more data will be digitized; high speed means a higher efficiency in the use of ship equipment. But for the shipping industry, more and more complicated sea environment, including natural environment and all kinds of unexpected events, also make people aware of the establishment of good communication with the ship and the importance of real-time monitoring of ship dynamic. In this paper, China’s own development based on the Beidou system, to use its characteristics of two-way data transmission and short message function, presents a method to realize the dynamic monitoring using the Beidou navigation system.The Beidou navigation system is a satellite navigation system developed by China, both the technical characteristics of positioning and communication. It has in marine monitoring, environmental monitoring and other industry wide utilization prospects. This paper gives the possibility and basis of ship dynamic monitoring through the Beidou navigation system. Secondly, further analysis of the Beidou navigation system for marine data transmission problems, first of all need to be solved by the existing Beidou system is a single data communication length limits, return the size of the data must be controlled; secondly, the need to solve is to avoid missing phenomenon in the transmission process of data, realization of guarantee the continuity of data in the transmission process in.The ship dynamic information of Beidou navigation system could eventually return back electronic chart display system, such as WebGIS platform appears, the user can also needs according to their own management, the superposition of other relevant data, matching display, in the actual management work can play a great role. |
