Because of their matching technologies, and after the integration, there will be more emerging industries, and the satellite navigation system of 5G and Beidou has a natural integration. Ran Chengqi, director of China Satellite Navigation System Management Office and spokesman of Beidou Satellite Navigation System, said that with the arrival of 5G, the integration of Beidou and 5G, artificial intelligence and emerging technologies will surely bring new industries and new economic growth points. The chief designer of Beidou satellite navigation system said that Beidou+5G will give full play to the natural characteristics of Beidou system integrating network, technology, service, terminal and application.
Realize the deep application of Beidou system in the information field. 5G network has the characteristics of large bandwidth, low delay and complex network cooperation. At the same time, the delay of 5G is milliseconds, which requires accurate clock timing. Various application scenarios of 5G, such as autonomous driving, intelligent manufacturing, smart city, traffic, geographic monitoring and virtual reality, all need accurate positioning services. Ran Chengqi T GR said that with the arrival of 5G, higher requirements will be put forward for time and place in the foreseeable future.
Only the satellite navigation system can provide more accurate position and time information. Beidou-3 uses a new generation of ruthenium atomic clock and the world-leading inter-satellite connection mode, which can reach the time accuracy of 1 nanosecond or better. Beidou-3 can be accurate to 1 centimeter in real time and 1 millimeter in specific areas after the incident through basic enhancement and space-based enhancement. It is understood that Beidou will soon build a low-orbit reinforcement system in the air.
after completion, it is estimated that the high-precision network will be completed in 225, and the whole world will enjoy Beidou centimeter-level positioning service. The coverage of 5G network makes up for the problem that Beidou navigation satellite can't cover indoor and other scenes, and transforms a large number of 5G base stations into fixed virtual navigation satellites. It has become a part of Beidou navigation system to spread navigation signals of satellite system by using mobile communication technology.
