Is the application scope of "Beidou constellation" getting wider and wider?

Since the navigation service was provided five years ago, Beidou system has been continuously enriched and improved. In the past five years, Beidou-2 system has been running steadily. Compared with 20 12, the positioning accuracy is improved from 10 m to 6 m. In order to improve the stability of the system, four spare satellites have been added, two of which have been launched into orbit.

At present, there are four global satellite navigation systems in the world: American GPS, Russian GLONASS, European Galileo and China Beidou. What is the competitive strength of Beidou system? "Beidou has the technical system or advantages of the other three systems. In addition, Beidou also has the ability of short message and location report service, which other systems do not have. Beidou is the first and only system that integrates communication and navigation. " Ran Chengqi said.

Another independent innovation feature of Beidou is high-precision service. "We have established a high-precision' One Net' based on Beidou in China. In the first half of this year, this "net" basically has the ability to provide high-precision services, which can provide high-precision services at the meter level and decimeter level, and some areas have achieved high-precision services at the centimeter level. High-precision services will bring revolutionary changes to the entire traditional location navigation service. " Ran Chengqi said that in China, high-precision location services are becoming public services like water and electricity.
