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 nationwide from the current 8 city pilots. 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. It is an innovative service launched by Beidou high-precision applications for the public, which will help Beidou in the industrialization of traffic travel scenes.

The latest data shows that the total output value of satellite navigation and location-based service industry in our country has reached about 470 billion yuan; as of January this year, the global cumulative access to intelligent devices of Beidou space-time intelligent services exceeded 1.50 billion units; Beidou high-precision space-time service was called more than 170 billion times a month, and the service covered more than 230 countries and regions around the world; Beidou became the "standard" of smart phones and wearable devices, and Autonavi maps called Beidou satellites for more than 300 billion times a day.

Beidou, which is "easy to use in the sky and good on the ground", has moved from solving the problem of "presence and absence" to a stage of development of "higher accuracy, more credibility and better service".

Scale applications continue to expand

In the northwest region, planting cotton requires high-precision linear film mulching. If the agricultural machine cannot guarantee the linear accuracy of the operation, it will not only affect the quality of the film mulching, resulting in "film cutting" and rework, but also not conducive to the later topping, harvesting and other links. At the same time, it will cause land waste, reduce production, and affect the income of cotton farmers.

Now, with the Beidou navigation agricultural machinery automatic driving system, cotton farmers only need to set the operation width and other data to ensure that the agricultural machinery is accurate and straight operation, on-demand seeds, ridge mulching and other procedures are completed in one go, and the sowing efficiency and quality are greatly improved. "In recent years, the’Huinong Beidou navigation automatic driving system ‘we have built is widely used in tractors, rice transplanters, harvesters, plant protection machines and some specific self-propelled vehicles, covering the whole operation link of plowing, sowing, transplanting, ditching, plant protection, harvesting, flat ground, etc. The operation accuracy can reach 2.5 cm, and the cumulative operation area of the system exceeds 50 million mu." Shen Jun, chief scientist of Beijing Hezhong Sizhuang Technology joint stock company, said.

Application is the life infra of Beidou development, and agriculture is the key area of Beidou application. In recent years, Beidou has supported the rapid development of precision agriculture in our country, and the agricultural machinery automatic driving system based on Beidou system has exceeded 100,000 units/sets. This year, the No. 1 document of the Central Committee proposes to support the integrated application of Beidou intelligent monitoring end point and auxiliary driving system.

From transportation to agriculture, forestry, animal husbandry and fishing, from smart ports to power inspections, Beidou provides time and space services like water, electricity, gas and other public services, fully integrated into the infrastructure, deeply empowering all walks of life, and gradually entering thousands of households, generating significant economic and social benefits.

In the bustling business center of Beijing, shared bicycles with Beidou high-precision positioning function are parked in the "electronic fence", which is convenient for users to use and convenient for staff to dispatch and clear in time. "These shared bicycles are equipped with Beidou high-precision positioning modules, which can achieve sub-meter-level (less than 1 meter) positioning accuracy in open scenes." According to Dou Ke, head of hardware research and development of Meituan bicycles, 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.

Data show 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 15.50 million units/set. At present, the number of shared bicycles equipped with domestic Beidou high-precision positioning chips has exceeded 5 million, covering more than 450 cities; among the smartphones applying for network access in China, the mobile phone shipments that support Beidou positioning account for more than 98%.

"Today, Beidou has become an important spatiotemporal infrastructure in our country, 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 vast world for Beidou applications. Industry and public application fields have created more and more digital application scenarios of Beidou, which has effectively expanded the breadth and depth of Beidou applications." Yu Xiancheng, president of China Satellite Navigation and Positioning Association, said.

Deep integration with emerging technologies

To communicate with each other and play an effective empowering role, data needs to have a unified temporal and spatial benchmark for "alignment". Only with accurate and reliable "space-time labels" can an accurate mapping of the real world and the digital world be achieved, and space-time-based perception, calculation and collaboration can be realized. With the combination of Beidou with artificial intelligence, big data, cloud computing, 5G communication, etc., Beidou applications are also extending to emerging technologies.

"Lane-level navigation" is a typical application of spatiotemporal intelligence, and it is also the product of the deep integration of Beidou and various emerging technologies. "The so-called’lane-level navigation ‘means that users can obtain extremely high-precision positioning provided by mobile navigation applications during driving. On this basis, when drivers need to change lanes, such as near expressway turning intersections or high-speed ramp,’ lane-level navigation ‘will provide more detailed lane-level voice broadcasts and action guidance." Liu Zhenfei, president of Autonavi Maps, introduced.

Chen Jinpei, chief executive of Qianxun Location Network Co., Ltd., said: "Technically, we observe the navigation satellite signal through the National Beidou Ground-based Enhancement System, and calculate the high-precision calculation engine to provide high-precision differential correction data to the end point of the mobile phone. After that, the mobile phone combines the original satellite observation data to complete the algorithm solution and obtain sub-meter positioning accuracy. Finally, the positioning and navigation application combines high-precision positioning maps to provide users with lane-level fine navigation guidance."

The successful application of "lane-level navigation" is inseparable from the all-round upgrade of positioning antennas, positioning algorithms, positioning chips, mobile phone maps and other technical elements. 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.

In the opinion of 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 in development and development in application, and should follow the concept of "financial network, financial data, financial end point, financial service", expand and strengthen the new business model of "Beidou +" and "+ Beidou", vigorously shape the consciousness of the whole industry chain, create an innovative consortium, realize the integrated development of the industry, and strive to be the first in the world to open up the full link of high-precision positioning of mobile phones.

Yu Xiancheng believes that space-time information, positioning and navigation services, as important information infrastructure, can only continue to maintain the leading and integration of technology, promote the development of application services to depth and breadth, and better and more fully empower space-time.

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. The "2022 China Satellite Navigation and location-based service industry development white paper" shows that in 2021, our country’s industrial core output value including chips, devices, algorithms, etc. directly related to the research and development and application of satellite navigation technology will reach 145.40 billion yuan, and the related output value driven by satellite navigation applications and services will reach 323.60 billion yuan. The number of enterprises and institutions in the field of satellite navigation and location-based service in our country is about 14,000, and the number of employees is over 500,000.

Yu Xiancheng said that the industrial application of Beidou is in a period of major change, and it is necessary to face the competition, find another way, and strive for advantages. By breaking through the key core technologies of the industry, we can promote the cross-integration of Beidou and digital technology, and promote the deep integration of Beidou and the industry.

Deqing County, Huzhou, Zhejiang Province, is a beneficiary of the development of the Beidou industry. It focuses on the advantageous industries of "Beidou Dixin", expands and forms industrial clusters such as "Beidou Dixin + artificial intelligence", "Beidou Dixin + general aviation", and gathers 2 provincial key laboratories, 2 provincial new R & D institutions, and 22 provincial high-tech enterprise R & D centers. It has successfully created the business card of "Geographic Information Town" and created considerable economic benefits.

"Promoting the development of the Beidou navigation and location-based service industry is an important means to accelerate the process of economic digital transformation and empower the development of the digital economy," Yu Xiancheng said. During the "14th Five-Year Plan" period, our country will further promote the standardization and ubiquitous development of Beidou, give full play to the role of Beidou as an independent time and space benchmark, and provide ubiquitous precise time and space information services, and truly realize the large-scale and market-oriented development of Beidou application services.
