Industry and Regional Functions of Beidou Global Satellite Navigation System

1, transportation, Beidou system is widely used in key transportation process monitoring, highway infrastructure safety monitoring, port high-precision real-time positioning scheduling monitoring and other fields. By the end of 20 18 and 12, Beidou system had been applied to more than 6 million operating vehicles, 30,000 postal and express vehicles, about 80,000 buses, more than 3,200 inland navigation facilities and more than 2,900 maritime navigation facilities in 36 central cities, and the world's largest dynamic monitoring system for operating vehicles had been built, which effectively improved the monitoring management efficiency and road transportation safety level. According to statistics, compared with 20 17 and 20 1 1, the number of serious accidents, deaths and missing persons in national road transport decreased by 50%.

2. In the field of agriculture, forestry and fishery, the agricultural machinery operation supervision platform based on Beidou has realized the remote management and accurate operation of agricultural machinery, served more than 50,000 agricultural machinery and equipment, increased the precision agricultural output by 5%, and saved the oil consumption of agricultural machinery by 10%. Positioning and short message communication functions have played a prominent role in forest fire prevention and other applications. Provide services such as ship position monitoring, emergency rescue, information release and fishing boat entry and exit management for fishery management departments. More than 70,000 fishing boats and law enforcement vessels across the country have installed the Beidou terminal, and more than 6,543,800 people have been rescued.

3. Hydrological monitoring has been successfully applied to the real-time transmission of hydrological forecasting information in mountainous areas, which improves the accuracy of disaster forecasting and provides important support for formulating flood control and drought relief dispatching schemes.

4. In the aspect of meteorological forecast, a series of Beidou terminal equipment for meteorological forecast have been developed, and a system application solution has been formed, which has improved the observation accuracy, automation level and emergency observation ability of domestic high-altitude meteorological detection systems.

5. In the aspect of communication timing system, the key technologies such as optical fiber stretching have been broken through, an integrated satellite timing system has been developed, and the Beidou bidirectional timing application has been developed.

6. In power dispatching, the application of power time synchronization based on Beidou has created conditions for high-precision time applications such as power accident analysis, power early warning system and protection system.

7. In disaster relief, based on the navigation, positioning and short message communication functions of Beidou system, it provides real-time disaster relief command and dispatch, emergency communication, disaster information quick report and * * * sharing services, which significantly improves the rapid response ability and decision-making ability of disaster emergency rescue.

8. In terms of public security, there are more than 400,000 police terminals connected to the police location service platform. Beidou system has played an important role in the security of Asia-Pacific Economic Cooperation (APEC) meetings, G20 summits and other major events.
