创始人2017-12-27
Let's take a look at the important achievements of the Beidou system since its fifth anniversary? What new highlights are being announced to the world.Ladies and gentlemen, to all media friends:Below, I will introduce the relevant situation from three aspects.1、 Construction and Operation of Beidou SystemBeidou System, based on its unique national conditions, pioneered the hybrid constellation design internationally, and created a technology system of navigation and positioning, short message communication, and differential enhancement integration. It won the 2016 National Science and Technology Progress Award and was selected as the leading scientific and technological achievement of the 2017 World Internet Conference.The Beidou-3 network has opened the curtain. Inheriting the characteristics of Beidou, benchmarking against world-class standards, adding new features such as inter satellite links and global search and rescue, and broadcasting navigation signals with better performance. Launch 5 experimental satellites, with an E-15 level stability of the onboard atomic clock and a positioning accuracy of 2.5 to 5 meters, which is 1 to 2 times higher than that of Beidou-2. Simultaneously carry out the construction of the Beidou satellite based augmentation system. On November 5, 2017, the first batch of networked twin satellites were successfully launched. Here, I will show you two interoperable new signal graphics, B1C and B2a, broadcasted by satellite. Today, the B1C and B2a signal interface control documents (version 1.0) were officially released, and the official Beidou website (www.beidou. gov.cn) will be launched simultaneously.Beidou's basic products have achieved a historic leap forward. Five years ago, there was no domestically produced Beidou chip in China. Nowadays, there is already a strong 'Beidou core'. The domestically produced Beidou chip has achieved large-scale application, with the process increased from 0.35 microns to 28 nanometers, and the lowest single chip price is only 6 yuan. The overall performance has reached or even exceeded that of similar international products. At present, the cumulative sales of domestically produced Beidou chips have exceeded 50 million pieces, and high-precision OEM boards and receiver antennas have respectively accounted for 30% and 90% of the domestic market share.Popular applications are within reach. In the past five years, Beidou has shifted from being "high-end" to "down-to-earth" and is increasingly approaching people's lives. Most mainstream mobile phone chips in the world support Beidou, and Beidou is becoming a standard configuration for smartphones sold domestically. Shared bicycles are equipped with Beidou to achieve precise management. Watches, bracelets, and student cards that support Beidou are more convenient and protect people's daily lives. Taking Beijing as an example, 33500 taxis and 21000 buses are equipped with Beidou, achieving full coverage of Beidou positioning; 1500 logistics trucks and 19000 delivery personnel are connected to the logistics cloud platform using Beidou terminals and wristbands to achieve real-time scheduling.China's Beidou, the world's Beidou. Beidou has gone abroad and is accelerating its integration into the world.
