Change a hardcore ＂face＂ Beidou is not just ＂navigation＂

　　Almost immediately, China’s Beidou has received two major announcements in the past month.

　　On August 31, the news from the sixth meeting of the China-Russia Satellite Navigation Major Strategic Cooperation Project Committee said that China and Russia have launched satellite navigation cooperation, and Beidou and GLONASS will achieve compatibility and interoperability. This is considered a new cooperation model between global satellite navigation systems and a new starting point for the world to share the development achievements of China’s Beidou.

　　In early August, under the guidance of the China Satellite Navigation System Management Office and sponsored by Chihiro Location, the "Beidou Intelligent Maker Program" was launched for the society, officially opening up a package of Beidou’s precise space-time technical capabilities to the outside world. And this is considered to be another accelerated landing of China’s Beidou applications.

　　As of August 28, the program has received nearly 500 applications from enterprises and universities, and students from Wuhan University, Wuhan University of Science and Technology, Southeast University and other universities are even more "menacing". A reporter from China Youth Daily and China Youth Network found that technology applications based on Beidou are coming, but these applications are not familiar "navigation" functions, but "new faces" connected to things such as smart triangle cards and airport wheel stops.

　　This is likely to become the latest trend in Beidou applications. Chen Jinpei, CEO of Chihiro Location, said that the general public may not need to know the exact location of individuals, but machines and objects serving humans need and can play a huge role in improving human productivity.

　　In fact, on the day the Beidou Intelligent Maker Project was launched, including Lu Mingquan, a professor of electrical engineering at Tsinghua University, Xu Ying, a doctoral supervisor at the Chinese Academy of Sciences, Feng Shaojun, the chief scientist of Chihiro’s position integrity and a fellow of the British Society of Engineering and Technology, came to the scene to "stand on the platform". Their recruitment letter to the society read –

　　"We are going to live in an era where every machine is becoming more’human ‘due to digital upgrades. Like humans, machines need to know where they are and what time it is. But the difference is that they need to know more precise spatial and temporal coordinates in order to be more capable."

　　Chen Jinpei told reporters that high-precision positioning is one of the differentiated services that distinguish Beidou from other global satellite navigation systems such as GPS. In the past, people may say that Beidou has few applications, but in the future, Beidou high-precision applications will not be less. "Today, whether it is a car, a mobile phone, or a drone, the demand for precise space-time developed by people is only 5%, and more than 95% of innovations based on precise space-time have not been stimulated."

　　For example, the "wheel gear" of an aircraft. Many people fly frequently, but may not have paid attention to the "wheel gear".

　　Just like cars on the ground, in order to avoid the car from slipping away, a baffle needs to be placed in front of the car when the car is parked in the parking space. However, an airport often has hundreds of wheel gears, which is not easy to manage. Due to various reasons such as flight density, aircraft type differences, and the physical strength of operators, safety hazards such as missed gears, late gears, and no gears often occur.

　　"What we want to do is that the information of the airport gear can be automatically uploaded to the cloud platform, without the need for operators to check the gear one by one. The cloud platform knows where the gear is, whether it has been removed by others, and whether it is in normal use." Wang Wei, general manager of Haiwei Technology, said.

　　His technology company has developed a smart wheel gear based on China’s Beidou sub-meter high-precision positioning service and other Internet of Things technologies. This technology can not only upload the position of the wheel gear in real time, but also upload the upper road status, withdrawal status, placement attitude, power, temperature and other information. Back-end managers can see the information of all wheel gears in the airport at a glance.

　　"We used to use GPS a lot, but the airport wheel gear requires high-precision positioning, so we considered switching to Beidou. Now that we have debugged it, it has greatly improved the original drift results." Now, Wang Wei’s team is also preparing to promote the system to airports and railway stations around the world.

　　In his opinion, after the arrival of 5G, the application scenarios of the Internet of Things will undergo tremendous changes. "The use of the Internet of Things will definitely exceed that of the Internet, because the Internet is for individual consumers, while the Internet of Things is for industries."

　　A small triangular warning sign can also become a microcosm of the development of Beidou’s precise time and space capabilities.

　　In the traditional scenario, when a vehicle breaks down on the road, the driver will place a triangular warning sign behind the car. Relevant regulations require that when a driving vehicle fails and cannot move, a triangular warning sign should be placed behind the car as soon as possible. Urban roads should be placed at least 50 meters behind the car, and expressways and expressways should be placed at least 150 meters behind the car to remind the following vehicles to avoid secondary accidents.

　　In 2018, the developers of Chihiro Location made a small modification to the triangular warning sign, with a built-in sub-meter-level Beidou high-precision positioning service and communication module that is less than 1 meter. This triangular warning sign has been "transformed" to achieve sub-meter-level positioning and upload its own location. By passing the data into the Autonavi map system, the Autonavi map can quickly mark the location of the accident on the map, and more timely and widely remind nearby vehicles to avoid it early.

　　According to Takasawa, the head of the development of this smart triangle card and the business director of Qianxun Location Website, due to the high-precision positioning, the Autonavi map can accurately capture the location of the triangle warning sign and identify the direction of the lane where the accident is located. "For example, whether the direction is north to south or south to north, optimize the navigation route and facilitate the user."

　　"In fact, there are many traditional industries like the warning triangle manufacturers, and the manufacturing threshold is not high, but if they do some’micro-innovation ‘, like the smart triangle warning sign, maybe they can change themselves from’Made in China’ to’Made in China ‘," Gao Ze said.

　　Chen Jinpei said that the development path of the Internet of Things is divided into three stages: "connection", "perception" and "intelligence". 5G will make the connection of Internet of Things devices more stable, and the finer granularity of location perception will also be one of the necessary conditions for the Internet of Things.

　　"At present, those who understand high-precision positioning in the field of innovation and entrepreneurship do not necessarily understand the development of the Internet of Things. Those who understand the development of the Internet of Things do not understand high-precision positioning. But to do the Internet of Things, accurate sensing of location cannot be avoided." Chen Jinpei said that in the future, high-precision positioning represented by China’s Beidou will truly become a helper for mankind like 5G.
