Mobile WebSiteWe see many new changes, such as high-precision application to wind power generation, which can increase the efficiency by more than 20%. With the arrival of 5G, revolutionary changes can be made in areas such as unmanned driving, autonomous driving, and drones. Chinese domestic companies are working to integrate Beidou high-precision applications with 5G, and make many innovative applications in autonomous driving and Internet vehicles. Of course, Internet cars are only one aspect, unmanned and intelligent must be the new changes brought by Beidou+5G.
Overcome difficulties and finish perfectly. Construction of Beidou-3 was launched in November 2009. Over the past 10 years, the project construction has gone through five stages of key technology research, experimental satellite engineering, minimal system, basic system, and complete system. The global constellation deployment was completed six months in advance and the full system service was opened. When completed, it will be opened, and when it is opened, the project has made great achievements. The first is to conquer key core technologies and achieve independent control. More than 400 units and more than 300,000 scientific and technical personnel have gathered wisdom to tackle key problems, overcome more than 160 key core technologies such as inter-satellite links, high-precision atomic clocks, and break through the localization of more than 500 device components, and realize the domestic production of Beidou-3 satellite core components The conversion rate is 100%. The second is to take advantage of the nationwide system to efficiently complete the network. Strengthen centralized and unified leadership, build a strong project overall and two general research teams, and innovate research and development systems based on overall, technology, quality, and progress. The single-satellite development cycle is shortened by a quarter, and the carrier rocket assembly cycle is shortened by a third , The satellite network access cycle is shortened by three quarters. Construct and form a risk analysis and control guarantee chain, launch without hidden dangers, and go to the sky without doubts.
Pursue excellence and be world-class. The construction goal is to benchmark internationally, iteratively upgrade, implement incremental projects, and achieve world-class functional performance indicators. One is the powerful system. Beidou-3 has two functions of navigation and positioning and communication and data transmission. It can provide 7 types of services including positioning and navigation timing, global short message communication, regional short message communication, international search and rescue, satellite-based enhancement, ground-based enhancement, and precise single-point positioning. , Is a powerful global satellite navigation system. The second is advanced performance indicators. The global positioning accuracy is better than 10 meters, the speed measurement accuracy is better than 0.2 m/s, the timing accuracy is better than 20 nanoseconds, the service availability is better than 99%, and the Asia-Pacific region has better performance.
Adhering to the development concept of "China's Beidou, the world's Beidou, and the first-class Beidou", we vigorously promote the new era Beidou spirit of "independent innovation, open integration, unity, and pursuit of excellence". It will be built by 2035 to be more ubiquitous, more integrated, A smarter national integrated positioning and navigation timing system will provide core support for future intelligent and unmanned development, continue to promote system upgrades, integrate new-generation communications, low-orbit enhancements and other emerging technologies, and vigorously develop quantum navigation, all-source navigation, Micro-PNT and other new qualitative capabilities to build a spatiotemporal information service infrastructure that covers the sky, the earth and the sea, has unified benchmarks, high precision, high intelligence, high security, and high efficiency. Serve the world and benefit mankind!
