The accuracy of the Beidou system built in 6 years is not inferior to GPS
At present, China has successfully launched 4 Beidou navigation test satellites and 16 Beidou navigation satellites, the second step goal of the "three-step" strategy of Beidou navigation project construction - Beidou satellite navigation regional networking has been successfully realized, and the accuracy and level of Beidou navigation system in the Asia-Pacific region are not inferior to GPS global positioning system. He said that China should speed up the formulation and improvement of relevant policies for the navigation industry and guide the orderly development of the navigation industry.
"China's Beidou satellite navigation system is developing very fast." Yang Yuanxi said that from the completion of the Beidou satellite navigation test system in 2000 to the official provision of regional services by the Beidou satellite navigation system at the end of 2012, and the formal provision of continuous passive positioning, navigation, timing and other services to most of the Asia-Pacific region, China has become one of the four major satellite positioning and navigation systems in the world in just over a decade.
According to the plan, by around 2020, China will build the Beidou global satellite navigation system composed of 5 geostationary satellites and 30 non-geostationary satellites to provide high-precision and highly reliable positioning, navigation and timing services covering the world.
"The Beidou satellite navigation system is a global satellite navigation system independently built and operated by China and compatible with other satellite navigation systems in the world. Although there is still room for improvement in some technical levels, from the perspective of operating effects, the accuracy and level in the Asia-Pacific region are not inferior to GPS. Yang Yuanxi said, "And Beidou has its own characteristics, not only navigation and positioning timing, but also communication functions." Insist on carrying forward their own characteristic advantages and providing high-quality services, then there will be a foothold in the domestic and future international markets. ”
"Urban development cannot be separated from three-dimensional space and time. Temporal and spatial information is the best reference and best record of urban development." Li Weisen, deputy director of the State Bureau of Surveying and Mapping, popularized his vision of a smart city from a professional perspective: Smart cities rely on modern information technologies such as the Internet of Things and cloud computing, supported by spatiotemporal information, to solidify human information into the construction, management, operation, service, and development of cities, forming intelligent operations that do not or rarely rely on humans
According to the relevant person in charge, in the field of centimeter level high-precision GNSS navigation and positioning technology, the Nebulas II (UC4C0) chip has reached international leading levels in technology, various indicators, and other aspects. The receiver board developed based on this chip can reduce its size by more than half.
According to media reports, US Trade Representative Michael Froman stated that China and the United States have made breakthroughs in negotiations to eliminate tariffs on information technology products. He expects these breakthroughs to lay the foundation for the Information Technology Agreement (ITA) negotiations to be held in Geneva at the end of the year. Froman said that China and the United States have reached an agreement on ITA expansion on the evening of the 10th, which will implement zero tariffs on various technology products, including GPS equipment. The other technology products mainly include medical equipment, video game consoles, semiconductors, and other new products.
At present, China has successfully launched 4 BeiDou navigation test satellites and 16 BeiDou navigation satellites. The second step of the "Three Step" strategy for the construction of BeiDou navigation engineering - the BeiDou satellite navigation regional network has been successfully achieved. The accuracy and level of the BeiDou navigation system in the Asia Pacific region is no less than that of the GPS global positioning system. He stated that China should accelerate the formulation and improvement of relevant policies for the navigation industry, and guide its orderly development.
According to the official website of the Civil Aviation Administration of China, Salvatore Shakitano, President of the Council of the International Civil Aviation Organization (ICAO), recently replied to the Civil Aviation Administration (CAAC), explicitly accepting the commitment made by Feng Zhenglin, Director of CAAC, on behalf of the Chinese government, to make the BeiDou ("Beidou System" for short) public service to ICAO. This marks the official consensus between China and ICAO on the Beidou system serving global civil aviation applications, laying a solid foundation for the subsequent review and formal inclusion of Beidou system standards in ICAO standards, and ultimately achieving the Beidou system serving global civil aviation applications.
Unmanned agricultural machinery used for farming in the fields, fishing boats used for ocean fishing, navigation software in mobile phones... In an increasing number of navigation and positioning scenarios, there is a similar Chinese core hidden - the "Beidou". According to data released by the China Satellite Navigation and Positioning Association, as of the end of 2020, the sales of domestically produced Beidou compatible chips and modules had exceeded 150 million pieces, with quarterly shipments exceeding 10 million pieces. The total social ownership of terminal products with Beidou positioning function exceeded 1 billion units, and the domestic output value of the Beidou system industry chain reached 403.3 billion yuan.
