Xinhua News Agency, Wuhan, June 1 (Reporter Li Siyuan) According to the Yangtze River Communications Administration of the Ministry of Transport, the Beidou satellite foundation enhancement system project of the Yangtze River trunk line undertaken by the bureau has recently passed the completion and acceptance of the Ministry of Transport, and has been officially put into operation and external service since the 1st. With the help of this system, the navigation accuracy of Yangtze River ships can be improved to sub-meter level.
The Beidou Satellite Ground Enhancement System Project on the Yangtze River Trunk Line is the Beidou service system with the largest scale, the widest coverage, the most complex network structure and the highest service performance requirements for inland river shipping in China. It started in November 2018. The total investment of the project is 107 million yuan, starting from Yunnan Shuifu in the west and about 2800 kilometers long and 30 kilometers wide in the east to the Yangtze River Estuary. The construction of 106 reference stations, 56 ship automatic identification system broadcasting stations, 154 network channels, 12 new computer rooms, and 2 data centers has realized the full coverage of the Beidou satellite ground enhancement signal on the Yangtze River.
Shen Jianjun, deputy director of the Yangtze River Communications Administration, said that as an important infrastructure for the information construction of the Yangtze River, the Beidou ground-based enhancement system of the Yangtze River trunk line can provide sub-meter navigation accuracy for ships, and centimeter-level and millimeter-level mapping accuracy services for surveying and surveying. At the same time, by empowering shipping elements in depth, accurate perception, accurate analysis, fine management and careful service, the capabilities of integrated traffic management, maritime safety supervision, and water traffic safety emergency command in the Yangtze River have been comprehensively improved.
According to the introduction, the Beidou ground-based enhancement service system of the Yangtze River trunk line will also encrypt the existing meteorological station observation network to further enhance the resolution of the Yangtze River meteorological monitoring.
Shen Jianjun said that in the next step, the Yangtze River Communications Administration will continue to carry out the application research and promotion of Beidou technology in Yangtze River shipping, and gradually realize the synergistic integration with 5G, artificial intelligence and data centers in key shipping elements such as key waters, important hubs, ports and logistics parks.
