    The intelligent application of Beidou global navigation satellite system in various scenes is the first to land in the field of transportation.

    On August 6, the Ministry of transport issued the guidance on promoting the construction of new infrastructure in the field of transportation. In terms of supporting the construction of information infrastructure, the document points out that it is necessary to promote the collaborative application of the fifth generation mobile communication technology (5g), the application of Beidou system and remote sensing satellite industry, strengthen the protection of network security, and promote the construction and application of data center and artificial intelligence.

    Beidou's high-precision geographic information system is the key to the construction of its high-precision geographic information system. It's not just transportation. Ran Chengqi, a spokesman for Beidou satellite navigation system, told a press conference recently that most smart phones already support Beidou function, and mobile phones that support Beidou ground-based enhancement and high-precision applications have come into the market.

    When many people subconsciously feel that Beidou is just a simple navigation satellite, its centimeter level high-precision positioning technology is accelerating the spread in all fields of people's lives, solving problems and initiating changes. As a high-precision service platform of Beidou, Chen Jinpei, a person of spatiotemporal intelligence industry, believed in an interview with 21st century economic reporter that after the completion of beidou-3 global satellite navigation system, the service coverage and innovative application have been expanded.

    High precision positioning

    On July 31, the beidou-3 global navigation satellite system was officially opened and a brilliant report card was handed over. The global positioning accuracy is better than 10 meters, the speed measurement accuracy is better than 0.2 meters / second, the time service accuracy is better than 20 nanoseconds, and the service availability is better than 99%. The Asia Pacific region has better performance.

    Ran Chengqi said that in the actual test process, the accuracy of Beidou system is 2-3 meters. With ground stations and satellites as carriers, Beidou enhanced station network can upgrade positioning to centimeter level in real time and millimeter level in post-processing. At present, Beidou related products have been exported to more than 120 countries and regions, which shows that the global networking of Beidou has been completed.

    And 137 countries have signed agreements with China, according to media reports. Financial institutions predict that the scale of China's satellite navigation industry will exceed 400 billion yuan in 2020, and Beidou will drive 300 billion yuan of this scale.

    Recently, the first large-scale road test of Beidou high-precision positioning has been launched in the industry, and the algorithm verification will be carried out on all expressways and major urban expressways in China. Beidou high-precision positioning road test will last nearly one year, and has completed 300000 km of road survey.

    According to the current test results, it can achieve the highest level of intelligent Lane positioning, i.e. it can meet the requirements of wide range of vehicle driving tests.

    As a matter of fact, one of the scientific and technological achievements of "Beidou + intelligent driving" has been implemented as early as June this year. In intelligent driving, high precision positioning technology has become the core element. More and more people in the industry realize that high-precision positioning can greatly improve the stability and safety of intelligent driving in various complex environments such as bad weather and repeated scenes.

    2020 is the "first year" of large-scale application of Beidou. Among them, in the field of intelligent driving, whether based on Beidou's high-precision space-time intelligent infrastructure or applications, are accelerating the upgrading or landing. In terms of application, on June 17, the first Beidou high-precision positioning 5g v2x intelligent car was officially launched.

    Relying on Beidou technology, the automatic driving system of the intelligent car will not be disturbed by factors such as line of sight occlusion and bad weather. In the safety functions of emergency brake warning and forward collision warning, it can reduce false alarm and missing report, and ensure the safety of vehicle owners, pedestrians and other traffic participants.

    Chen Jinpei said that Beidou will be the infrastructure of intelligent connected vehicles, including road builders, automobile manufacturers, various equipment and application developers, etc. This year, several vehicles equipped with Beidou high-precision positioning will be released in mass production. In addition to the precise positioning of the bicycle itself, it also provides high-precision positioning and timing capabilities for the intelligent driving vehicle road coordination (v2x).

    Spatiotemporal intelligence

    In addition to four-wheel intelligent driving, Beidou high-precision positioning is also enabling sharing two-wheel travel. On July 30, the "high precision vehicle positioning and electronic fence parking technology" developed by Harlow travel partners was unveiled in Shanghai. This technology enables shared bicycles and shared mopeds to form a higher spatial resolution perception, and the positioning accuracy can reach sub meter level.

    Ren Liangliang, vice president of Harlow travel, revealed in an interview with 21st century economic reporter that high precision positioning can help enterprises more accurately grasp the real-time location distribution, quantity and operation of shared two wheeled vehicles. Meanwhile, it also allows users to find vehicles more conveniently and accurately, and reduce the misjudgment rate of parking in over zone and no parking zone. "It is mainly to reduce the cost investment in operation and maintenance personnel of bicycle sharing enterprises."

    It is reported that the technology has been launched in some cities and will be launched in large scale in the near future. This also marks the first large-scale application of Beidou navigation system in the field of shared travel. In addition to transportation applications, Beidou is entering various application scenarios, including surveying and mapping, intelligent city, public services, industry upgrading and other five fields.

    Ren Liangliang believes that positioning is a very basic ability. "In order to solve the positioning problem, we have to solve it through many high-cost technical means and do a lot of infrastructure construction. And a set of relatively ordinary, universal, and cheap solutions will bring great changes to the whole industry. "

    It is reported that in terms of Beidou satellite system alone, 70% of the newly shipped mobile phones have integrated Beidou signals. In the future, a complete industrial chain integrating chips, modules, boards, terminals and operation services will be built. At present, the a-beidou accelerated positioning service serves more than 600 million users worldwide, with 80% of Chinese users.

    Beidou satellite navigation system website information shows that Beidou technology has entered more than ten industries, including transportation, agriculture, disaster prevention and mitigation. Besides navigation and positioning, it provides applications such as navigation application, farmland information collection, vehicle command and dispatching, building, bridge and reservoir detection, power grid time basis unification, etc.

    Combined with 5g, cloud computing, Internet of things and other technologies, Beidou provides problem solutions in a variety of scenarios. Taking Yangshan Port in Shanghai as an example, the "Beidou + 5g" automatic driving heavy-duty truck accurately stops in the narrow warehouse location, realizes centimeter level positioning, the loading and unloading error is ± 3cm, and the single point loading and unloading operation efficiency is increased by 10%.

    Chen Jinpei said that with high precision, Beidou's satellite system has changed from a navigation system to a space-time intelligent infrastructure. The so-called spatiotemporal intelligent infrastructure means that it can give a unified time and space benchmark to a variety of intelligent devices and application scenarios.

    However, in his view, the demand for precise space-time is only developed by 5%. "There are still more than 95% of the innovation based on the mobile phone and the mobile phone. We hope to open up large-scale precision space-time technology through the Beidou intelligent maker program, so that all kinds of developers can create new terminals. " Chen Jinpei further pointed out that not only mobile phones and automobiles, but also Beidou will play a more important role in integrating into 10 billion level IOT devices and scenarios in the future.

    Huatai Securities believes that with the opening and operation of Beidou No.3, the gradual popularization of 5g network, and the acceleration of CORS network construction by operators, the intelligent application of "Beidou + 5g" technology is further mature, and it is expected to open up tens of billions of new application scene market.
