Not long ago, the General Office of the State Ministry of Industry and Information Technology identified 39 cities in the country as pilot cities for the scale application of Beidou in the field of industry and information technology, and Nanjing was successfully selected.
Around the Beidou system, there are currently two main tasks: "Beidou+" and "+Beidou"."Beidou+" focuses on integration and innovation, mainly promoting the integration and development of Beidou technology products and its services with other technologies and services. While "+BeiDou" focuses on spatial and temporal applications, i.e., using BeiDou technology as an enabling means to promote the transformation and upgrading of the traditional economic model and the development of traditional industries.
As a typical representative of new productivity, the development of BeiDou application depends largely on innovation. With satellite-driven innovation, how can Nanjing be "star" and "new" with Beidou?
01 Scientific and technological innovation for the "Beidou +" to explore more possibilities
At 09:14 on September 19, 2024, China once again successfully launched Beidou satellites from the Xichang Satellite Launch Center, bringing the number of Beidou navigation satellites in orbit to 64 (including four test satellites).
The bright Dipper shines with "Nanjing Power" in the starry river.
BeiDou satellites use customized screws and guide rails made by Nanjing Craft Equipment Manufacturing Co., Ltd; millimeter-wave phased array chips developed by Zijinshan Laboratory are the key core devices for broadband satellite communications; nearly 300 enterprises in the field of satellite navigation have formed a full-coverage in the BeiDou navigation chips, components, modules, antenna assemblies, terminal equipment, software research and development, and location-based operation services, and other sectors. ......
Relying on industrial and talent resources, in recent years, a number of "Beidou +" empowered science and innovation exploration is accelerating in Nanjing.
In 2020, Wuhan University and the People's Government of Liuhe District, Nanjing jointly funded the construction of the Nanjing Beidou Innovation and Application Science and Technology Research Institute. The institute gathers multidisciplinary talents and scientific research results from the State Key Laboratory of Surveying and Mapping Remote Sensing Information Engineering and the National Engineering and Technical Research Center for Satellite Positioning System, introduces Wuhan University and other scientific and technological innovation resources, focuses on the deep integration of Beidou's socialized applications and traditional industries, and promotes the transformation and industrialization of scientific and technological achievements.
In 2021, SINOPEC laid out its Beidou operation and service center in Nanjing. As a time and space location service center, the center will provide all-weather, all-day high-precision positioning, navigation, timing and short message communication services for SINOPEC's upstream, midstream and downstream industry chain relying on the Beidou system.
The "Beidou Zhixing" shared motorcycle placed in Luhe District, Nanjing City, uses the first industry-wide application of Beidou RTK positioning technology, with a positioning accuracy of up to centimeter level. Relying on "Beidou + 5G + high-precision maps", the project is expected to provide more scientific and comprehensive solutions to the three major difficulties in the shared motorcycle industry, namely "stopping, traveling and managing".
As early as 2010, Nanjing will start to develop the Beidou satellite industry planning, satellite navigation industry development over the years into a momentum.At present, the city's Beidou industry covers the whole industry chain of Beidou navigation chips, components, modules, antenna components, terminal equipment, software research and development, location-based operation services, etc. It has gathered key enterprises related to the application of Beidou, such as Jiangsu Beidou Research Institute, Starry Core Union, DuoLun Technology, and Zhongtian Anchor, etc., and formed a Beidou industrial park in the spatial layout, which is represented by Jiangbei New Area, Jiangning District, Yuhuatai District, and Gulou District, with "one core and three areas". "In terms of spatial layout, the Beidou Industrial Park has been formed with Jiangbei New District, Jiangning District, Yuhuatai District and Gulou District as its representatives.
02 New scenarios link "+Beidou" to a wider world
Zhu Jiubao is Liuhe District Jiu Ming agricultural machinery service professional cooperatives in charge, he said: "With the help of Beidou, agricultural machinery learned to unmanned, and now work is much more convenient."
In the field, Zhu Jiubao only needs to open the Beidou agricultural machinery housekeeper on the cell phone, press the ignition, start and other keys, the agricultural machinery will operate in accordance with the platform's planned path, and the average error of trajectory tracking is within 2.5 centimeters. Since the beginning of 2018, Jiu Ming Cooperative began to install the Beidou system on tractors, harvesters, rice transplanters and other agricultural machines one after another, and the existing 40-odd agricultural machines have all been installed. More than just more accurate navigation, the addition of the Beidou system has allowed the base to maintain yields while realizing an average of 20% of drug reduction and more than 10% of weight loss per mu.
In Liuhe District agricultural socialized services digital management platform, the region's more than 1,000 sets of tractor, rice transplanter, planting machine, combine harvester with intelligent terminals of the Beidou agricultural operation sketched the blueprint of the harvest. In addition, the platform also expanded the online release of demand, undertake business and other functions, set up the main body of production, agricultural machinery, the main body of the service to contact the bridge, to a certain extent, to alleviate the "agricultural machinery can not find agricultural work" "agricultural work can not find agricultural machinery" situation.
From Nanjing, Jiangsu Beidou Agricultural Machinery has expanded to more than 20 provinces, municipalities and autonomous regions across the country, serving more than 200,000 sets of agricultural equipment and supervising billions of mu of cumulative operating area.Jiangsu Beidou ranked first in the sales of intelligent monitoring terminals for agricultural machinery operations for the whole year of 2023 released by China Agricultural Machinery Industry Association.
In August this year, the eVTOL electric vertical take-off and landing aircraft, known as the "air cab", made its first cross-river flight in Nanjing. This type of aircraft from the Pukou District of Nanjing City UAV base took off, flying over the Yangtze River and along the river circling cruise back to the base, 25 kilometers of range in only 10 minutes. Not only cross-river, Nanjing metropolitan area cross-city travel will also open up short shuttle routes "Lukou - Liyang" and "Lukou - Yangzhou" line.Through helicopter connection, you can reach Liyang in 23 minutes and Yangzhou in 37 minutes from Lukou Airport, saving more than double the time.
Air routes more up, the service guarantee is particularly important. Recently, by the Nanjing big wing aviation technology limited company independent research and development "kite line unmanned aircraft management system" in nanjing data trading platform on the shelves, this is the province's first low altitude economic data products, as of August has access to nearly 3,000 units. The platform integrates the Internet of Things, the Internet and Beidou satellite data information, which can support collaborative planning and command and scheduling of drone missions.
03 Scale application pilots, where and how to use them?
The Notice on Announcing the List of Pilot Cities for Scale Application of Beidou in the Field of Industry and Informatization issued by the Ministry of Industry and Information Technology (MIIT) shows that the main directions of the national pilot program for scale application of Beidou are in the three fields of mass consumption, industrial manufacturing and convergence and innovation. Combined with the actual development of Nanjing, the Nanjing Municipal Bureau of Industry and Information Technology said that theIn the future, it will focus on the segmented directions of low-altitude economy, shared travel, intelligent networked vehicles, smart grid, industrial Internet, advanced communications, etc., and make every effort to enhance the energy level of the city's Beidou scale application.
