The Deployment of Beidou Global Satellite Navigation System Constellation Has Been Fully Completed

How does Beidou operate after networking? What impact will it have on life? Recently, with the full completion of the constellation deployment of Beidou global satellite navigation system, the reporter learned that relying on the Beidou satellite network in the sky and the Beidou foundation enhancement system on the ground, Beidou will burst out more vitality with stronger functions and better performance, enabling all industries to serve the world and benefit mankind.Smart "brain" is busy with management and full online coverage at any timeBeidou navigation is a huge and complex aerospace system project. The coordinated operation of its heaven earth networking involves the overall scheduling, monitoring and management of dozens of systems and tens of thousands of sets of equipment. How to ensure that they "act in unity and listen to the command"?

At China Electronics Technology Group Co., Ltd., technicians introduced that the beidou-3 management and control center developed by CETC is equivalent to a smart "brain", which can command the coordinated operation of space segment and ground segment, the overall scheduling of ground antenna and various observation equipment, as well as the editing and annotation of navigation messages.In order to realize the satellite ground integrated management and control of Beidou satellite navigation system, CETC has overcome a number of key technologies, developed a number of innovative achievements, finally realized the tracking and measurement of satellites in the whole network, and solved the control problems of dozens of systems and tens of thousands of sets of equipment.In order to ensure the safe launch, successful orbit entry and stable operation of the Beidou satellite launch mission, CETC has arranged ground radar, ground measurement and control station, marine measurement ship and relay satellite in an all-round way, creating a full coverage measurement and control network to provide online services at any time for the aerospace measurement and control of Beidou satellite.

There are nets in the sky and on the earth, and the foundation is strengthened to helpNot only the Beidou satellite network in the sky, but also the Beidou foundation enhancement system on the ground.Beidou ground-based enhancement system is an important part of Beidou satellite navigation system. Its development and construction was started in September 2014. China Ordnance Industry Group Co., Ltd. undertakes the overall task of system construction. It integrates four types of high-precision services: meter level, decimeter level, centimeter level and post-processing millimeter level in one system, which is the first at home and abroad.

At present, the system has formed a "national network" of Beidou foundation enhancement system composed of more than 2500 foundation enhancement stations, and the system capacity has reached the technical level of similar systems abroad.In August 2015, the China Weapon Industry Group set up a high precision location service platform, the location network of thousands of search, which takes the high-precision as the breakthrough point, and integrates the development of "Internet plus" and "Beidou " to create a high-precision service cloud platform, and is committed to making Beidou high-precision space-time service to serve the public, accessible and demand based services."Beidou is not only a satellite navigation system deployed at high altitude, but also a major national space-time infrastructure closely related to everyone." Chen Jinpei, CEO of Chihiro position, said that there is Beidou satellite system in the sky and Beidou foundation enhancement system on the ground. Satellite signals on the ground sometimes need to be strengthened according to the actual situation.

In recent years, Beidou's high-precision and Beidou assisted rapid positioning users have exceeded 500 million. At present, China ordnance industry group, together with China Mobile and CETC, is stepping up the construction of Beidou No. 3 regional short message application service platform, which will effectively promote the integration and innovation of Beidou high-precision and short message services with 5g, big data and cloud computing."Beidou" flies into people's homes and empowers all walks of lifeExpress delivery delivery vehicles can assist the public security traffic police in obtaining evidence and participating in urban emergency dispatching and rescue. The distribution of urban consumption areas can be analyzed from the positioning data of distribution vehicles. Express companies can optimize the distribution path by analyzing distribution data and driving data

In Zhejiang, a series of applications based on Beidou spatial positioning technology are gradually becoming a reality with the successful launch of the last beidou-3 networking satellite into orbit."After the successful networking, Beidou spatial positioning technology will be more applied to the field of people's livelihood." Chen Zhengwei, technical director of Hangzhou Beidou space-time Research Institute, said that Beidou is not only a simple positioning and communication, but also as the basis of upper application, but also has a broader application space.Using Beidou's high-precision spatial positioning technology, Beidou's high-precision positioning module is installed locally for delivery and express delivery vehicles, and the vehicle's road trajectory is displayed on the map in real time through real-time upload of geographical location.

"The error is only centimeter level, which can accurately judge the driving situation of vehicles on the road. The background can judge whether vehicles run red lights and illegally stop through data calculation, so as to achieve industry autonomy and standardization," Chen Zhengwei said.In addition, the application of Beidou technology can also assist the public security traffic police in obtaining evidence in major cases or accidents. These distribution vehicles will also be incorporated into the urban emergency dispatching system in the future. In case of emergencies requiring rescue, Beidou Positioning Technology will be used to quickly find nearby vehicles as reinforcements.
