"Urban development is inseparable from three-dimensional space and time. Spatiotemporal information is the best reference and the best record of urban development. Li Weisen, deputy director of the National Administration of Surveying, Mapping and Geographic Information, "popularized" the smart city in his eyes from a professional point of view
"Smart city is to rely on modern information technology such as the Internet of Things and cloud computing under the support of spatiotemporal information, solidify human information into the construction, management, operation, service and development of the city, and form an intelligent operation that does not depend on people or rarely relies on people."
Li Weisen believes that the construction of smart cities should start from three aspects: 1. infrastructure construction in hardware, network, transmission and other aspects; 2. Spatiotemporal information infrastructure; 3. Intelligent improvement in various fields and industries.
From digital city to smart city, the National Administration of Surveying, Mapping and Geographic Information currently focuses on four aspects: 1. Rich data, and great enrichment of diversified data; 2. Introduce the time dimension; 3. Technical methods should be improved; 4. Increased intelligence. Li Weisen believes that "whether the construction of smart cities is informatized or intelligent, social geographic information must first go and must be the foundation."
In the specific urban "intelligent" construction, whether a unified set of indicators is needed is still being debated and explored. However, the top-level mechanism of smart city standardization is indispensable in the early stage of construction and promotion.
Yin Minghan, Chief Engineer of the National Standards Committee, said: "Smart city standardization is the basic guarantee for the orderly and healthy development of smart cities, a necessary condition for promoting the aggregation, sharing, development and utilization of urban information resources, and an important support for promoting the effective application of emerging technologies such as cloud computing, Internet of Things, big data, and mobile Internet in smart city construction." ”
Yin Minghan gave reasons for the necessity of standardization: "The architecture of a smart city is a so-called system system, involving information, remote sensing, communication, urban management, and planning and many other fields, which is a complex system engineering, and standardization work needs to effectively use and integrate the standardization basis of various fields." ”
What the National Standards Committee has done in the process of specific promotion is: to build a cross-field and cross-departmental standardization collaboration platform; Established the Smart City Standardization Coordination and Promotion Overall Group and the Expert Advisory Group; From the three levels of expert consultation and decision-making suggestions, standard coordination and division of labor development, in accordance with the overall plan, jointly promote, distribute implementation, and jointly carry out relevant work.
The current progress is: in 2013, the National Standards Committee issued five ideal plans for standard city national standards, covering smart city technology, reference models, evaluation models, unit evaluation systems, and SOA application guidelines and other basic standards.

Beidou Xingtong Releases a New Generation GNSS Navigation and Positioning Chip
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.
Imported GPS equipment may be duty-free, and domestic industry faces challenges
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.
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 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.
China's BeiDou public service commitment won the International Civil Aviation Organization
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.
Beidou Civil Demonstration Leading Innovation in the Freight and Logistics Industry
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.
