The Chinese Beidou Writes a New Chapter of Human Time and Space Civilization
In the development process of Beidou satellite navigation system, we have embarked on a road of construction of satellite navigation system with Chinese characteristics from scratch, from existence to excellence, from active to passive, from regional to global, and cultivated the spirit of Beidou in the new era of "independent innovation, openness and integration, unity and pursuit of excellence".
The first hybrid heterogeneous constellation in medium and high orbit; For the first time, the integrated networking operation between satellites and satellites and between satellites and the ground is realized through inter-satellite links. Break through key technologies such as modulation mode, multiplexing, channel coding, etc., and take the lead in realizing all-constellation three-band services... The independent research and development of a series of core technologies behind China's Beidou shows China's ambition and backbone to achieve high-level scientific and technological self-reliance and self-improvement, interprets the spirit and will of the Chinese people to be independent, self-reliant, hard struggle, and overcome difficulties, and fully reflects the political advantages of China's socialist system in concentrating forces to do great things.
Independent innovation is the core competitiveness of China Beidou, and the pursuit of excellence is the eternal goal of China Beidou. Looking forward to the future, China Beidou will still unswervingly take the road of independent innovation. Build a Beidou system with more advanced technology, more powerful functions and better services, build a more ubiquitous, more integrated and more intelligent comprehensive spatial-temporal system, provide highly flexible, highly intelligent, high-precision and highly safe positioning and navigation timing services, better benefit people's livelihood and well-being, serve human development and progress, and write a new chapter of human space-time civilization.
What remains unchanged is the eternal dream of the Chinese nation to explore the boundless universe for thousands of years, and what remains unchanged is the broad-mindedness that benefits both China and the world. Beidou system has always adhered to the development concept of "China's Beidou, the world's Beidou, and first-class Beidou", and has been widely used worldwide and empowered all walks of life. China will continue to do a good job in ensuring the stable operation of the system and other follow-up work, and make new and greater contributions to promoting China's economic and social development and promoting the construction of a community with a shared future for mankind.
"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.
