China News Service, Xi’an, August 13th (Reporter Mei Yilong Alina) On the 13th, the reporter learned from the Geodetic Data Processing Center of the Natural Resources Department of the Shaanxi Provincial Bureau of Surveying, Mapping and Geographic Information that the center will join the 14th National Games in Xi’an. The Municipal Executive Committee has developed the “Beidou Positioning Service System for the Torch Relay of the 14th National Games” to provide real-time dynamic and precise positioning for the Torch Relay of the 14th National Games.

It is understood that based on China’s Beidou satellite navigation system, during the “13th Five-Year Plan” period, Shaanxi Province has built a Shaanxi Beidou satellite navigation and positioning reference station network consisting of 136 Beidou reference stations and 1 numerical control center. It is China’s first high-precision positioning application service system that supports full constellation, full frequency, and full Beidou on the entire network. It can achieve precise positioning with a plane better than 3 cm and an elevation better than 5 cm across Shaanxi.

“The Beidou positioning service system for the torch relay of the 14th National Games of the People’s Republic of China” is based on China’s Beidou satellite navigation system, using the accurate differential signals provided by the Shaanxi Beidou reference station system, combined with GIS (geographic information) , Internet, mobile applications, cloud services, big data and other technologies provide real-time dynamic and precise positioning for the torch relay of the 14th National Games.

It is reported that the fire relay ceremony at the first site of the 14th National Games will be held in Xi’an on August 16. Torchbearers and escorts will wear Beidou chips to receive real-time positioning during the torch relay. Signals, the system will be displayed live on the mobile phone and online maps, and can learn about the torch relay in Xi’an City Station of the 14th National Games in time, understand the torchbearer’s position, introduction, real-time location, transmission distance, introduction of scenic spots along the route and other information.

The research and development of this system can not only increase the public’s attention to the torch relay, but also the specific measures taken by the Shaanxi Provincial Bureau of Surveying, Mapping and Geographic Information to implement the country’s promotion of the large-scale application of Beidou. “This is a manifestation of Beidou’s entry into the lives of the people.” Huang Gongwen, director of the Beidou Navigation and Positioning Center of the Geodetic Data Processing Center of the Ministry of Natural Resources, said that in the future this kind of precise positioning service can also be applied to more scenarios, such as the elderly, children, and vehicles. Location, search for food and lodging information in the surrounding area, etc. (End)
