Reporter Gu Yekai
Recently, the "Beidou Travel Application Innovation Plan" initiated by domestic enterprises was launched, and the Beidou innovative application represented by "lane-level navigation" will be popularized from the current 8 cities to the whole country. It is understood that the plan also includes functions such as dynamic traffic light countdown and equal light status based on Beidou's core computing power, which is an innovative service launched by Beidou's high-precision application to the public, and will help Beidou industrialize in traffic scenarios.
The latest data shows that the overall output value of China's satellite navigation and location service industry has reached about 4700 billion yuan; As of January this year, Beidou spatiotemporal intelligent services have accumulated more than 1.15 billion smart devices connected worldwide. Beidou's high-precision spatiotemporal service has more than 1700 billion monthly calls, covering more than 230 countries and regions around the world. Beidou has become the "standard" for smartphones and wearable devices, and Amap's daily positioning of Beidou satellites exceeds 3000 billion times.
Beidou, which is "easy to use in the sky and good on the ground", has entered the development stage of "higher precision, more credible and better service" from solving "whether there is or not".
Large-scale applications continue to expand
In the Northwest Territories, growing cotton requires high-precision linear lamination. If the agricultural mechanic cannot ensure the linear accuracy of the operation, it will not only affect the quality of the lamination, cause the "cutting film" rework, but also not conducive to the later topping, harvesting and other links, and at the same time will cause land waste, yield reduction, and affect the income of cotton farmers.
Now, with the Beidou navigation agricultural machinery automatic driving system, cotton farmers only need to set the working width and other data, can ensure the precise and straight operation of the agricultural machinery, on-demand seeds, ridge mulching and other procedures in one go, sowing efficiency and quality greatly improved. "In recent years, the 'Huinong Beidou Navigation Automatic Driving System' created by us has been widely used in tractors, rice transplanters, harvesters, plant protection machines and some specific self-propelled vehicles, covering the whole operation links such as ploughing, seeding, transplanting, ditching, plant protection, harvesting, and leveling, with an operation accuracy of up to 2.5 cm and a cumulative operating area of more than 5000 million mu." Shen Jun, chief scientist of Beijing United Strongang Technology Co., Ltd., said.
Application is the lifeline of Beidou's development, and agriculture is the key area of BeiDou's application. In recent years, Beidou has supported the rapid development of precision agriculture in China, and the automatic driving system of agricultural machinery based on the Beidou system has exceeded 10,<> units/sets. This year's Central Document No. <> proposed to support the integrated application of Beidou intelligent monitoring terminal and assisted driving system.
From transportation to agriculture, forestry, animal husbandry and fishery, from smart ports to power inspection, the spatial-temporal services provided by Beidou are fully integrated into infrastructure like public services such as water, electricity and gas, deeply empowering all walks of life, and gradually entering thousands of households, generating significant economic and social benefits.
In the bustling Beijing CBD, shared bicycles with Beidou's high-precision positioning function are parked in the "electronic fence", which is convenient for users to use and convenient for staff to dispatch and clean up in time. "These shared bicycles are equipped with Beidou high-precision positioning module, which can achieve submeter-level (less than 1 meter) positioning accuracy in open scenes." Dou Ke, head of hardware research and development of Meituan bicycles, said that in order to further improve the real-time and accuracy of positioning, they have upgraded the smart lock chip of shared bicycles from 2G to 4G, and equipped with more advanced sensors to make vehicle scheduling more orderly.
The data shows that as of the first half of 2022, Beidou has been applied in more than 20 industries (fields). The total application of Beidou products has exceeded 1550.500 million units/sets. At present, the number of shared bicycles equipped with domestic Beidou high-precision positioning chips has exceeded 450 million, covering more than 98 cities; Among the smartphones applying for network access in China, mobile phones that support Beidou positioning account for more than <>% of shipments.
"Today, Beidou has become an important space-time infrastructure in China, and has also played an important supporting role in the development of the digital economy. The spatiotemporal data generated by Beidou is the 'blood' of the digital economy, and the massive data accumulated by the digital economy provides a broad space for Beidou applications. The industry and mass application fields have created more and more Beidou digital application scenarios, which has effectively expanded the breadth and depth of Beidou applications. Yu Xiancheng, president of the China Satellite Navigation and Positioning Association, said.
Deep integration with emerging technologies
If data wants to communicate and play an effective enabling role, it is necessary to have a unified temporal and spatial benchmark for "alignment", and only with accurate and reliable "spatiotemporal labels" can we achieve accurate mapping of the real world and the digital world, and realize spatiotemporal perception, computing and collaboration. With the combination of Beidou with artificial intelligence, big data, cloud computing, 5G communication, etc., Beidou applications are also extending to emerging technology fields.
"Lane-level navigation" is a typical application of spatiotemporal intelligence, and it is also the product of the deep integration of Beidou and a variety of emerging technologies. "The so-called 'lane-level navigation' means that users can obtain extremely accurate positioning provided by mobile phone navigation applications during driving; on this basis, when drivers need to change lanes, such as near expressway turning intersections or high-speed ramps, 'lane-level navigation' will provide more refined lane-level voice broadcast and action guidance." Liu Zhenfei, president of AutoNavi Map, introduced.
Chen Jinpei, CEO of Chihiro Location Network Co., Ltd., said: "In terms of technical principles, we provide high-precision differential correction data to mobile terminals through the observation of navigation satellite signals by the National Beidou Ground-based Enhancement System and the calculation of high-precision computing engines. Later, the mobile phone combines it with the original observation data of the satellite to complete the algorithm solution to obtain submeter-level positioning accuracy. Finally, the positioning and navigation application combined with high-precision positioning map provides users with lane-level refined navigation guidance. ”
The successful application of "lane-level navigation" is inseparable from the all-round upgrade of technical elements such as positioning antennas, positioning algorithms, positioning chips, and mobile phone maps. Since 2019, domestic enterprises have carried out joint research in a number of software and hardware fields, and made breakthroughs in reducing the power consumption of positioning antennas, real-time dynamic measurement technology algorithms, and deep adaptation of mainstream chip manufacturers.
According to Yang Changfeng, chief designer of Beidou satellite navigation system engineering and academician of the Chinese Academy of Engineering, China Beidou in the new era insists on application and development in development, and should follow the concept of "integrating network, data, terminal and service", expand and strengthen the new format of "Beidou+" and "+Beidou", vigorously shape the awareness of the whole industrial chain, create an innovative consortium, realize industrial integration and development, and strive to take the lead in the world to open up the whole link of high-precision positioning of mobile phones.
Yu Xiancheng believes that as important information infrastructure, spatiotemporal information and positioning and navigation services can only be supported with other innovative infrastructure and converged infrastructure to achieve interaction and mutual promotion, so as to continuously maintain the leadership and integration of technology, promote the development of application services to depth and breadth, and better and more fully realize spatiotemporal empowerment.
Industrial development ushered in a period of opportunity
At present, the large-scale application of Beidou has entered a critical period, and it is also an opportunity period for the development of the entire Beidou industry. According to the "2022 China Satellite Navigation and Location Service Industry Development White Paper", in 2021, the core output value of China's industry, including chips, devices, algorithms, etc. directly related to the research and development and application of satellite navigation technology, reached 1454.3236 billion yuan, and the associated output value formed by satellite navigation applications and services reached 1.4 billion yuan. The number of enterprises and institutions in the field of satellite navigation and location services in China is about 50,<>, and the number of employees exceeds <>,<>.
Yu Xiancheng said that the industrialization application of BeiDou is in a period of major change, and it is necessary to face competition, find another way, strive for advantages, and promote the cross-integration of BeiDou and digital technology by breaking through the key core technologies of the industry, and promote the deep integration of BeiDou and the industry.
Deqing County, Huzhou, Zhejiang Province, is a beneficiary of the development of Beidou industry. It focuses on the advantageous industries of "Beidou Dixin", expands and forms industrial clusters such as "Beidou Dixin + Artificial Intelligence" and "Beidou Dixin + General Aviation", brings together 2 provincial key laboratories, 2 provincial new R&D institutions, and 22 provincial high-tech enterprise R&D centers, successfully creating the business card of "Geographic Information Town" and creating considerable economic benefits.
"Promoting the development of Beidou navigation and location service industry is an important means to accelerate the digital transformation of the economy and empower the development of the digital economy." Yu Xiancheng said that during the "14th Five-Year Plan" period, China will further promote the standard and ubiquitous development of Beidou, give full play to the role of Beidou as an independent time and space benchmark and provide ubiquitous and accurate spatiotemporal information services, and truly realize the large-scale and market-oriented development of Beidou application services.
