How will our lives change in the "Beidou Era"

　　The successful launch of the 55th Beidou navigation satellite means that China's self-constructed and independently operated global satellite navigation system-Beidou Global Network has been successfully established, which can provide users with high-precision positioning and navigation all-weather and all-day on a global scale. , Time service, and unique short message communication capabilities. What concrete changes will this bring to our lives? Compared with the GPS and other navigation commonly used in mobile phones and vehicles, what are the differences?

Strong anti-interference ability

　　Take the most common shared bicycles on the road as an example. On June 23, Haro Travel announced that its bicycles were fully integrated into Beidou positioning. What changes will be made to the Beidou positioning system compared to the previous GPS?

　　"GPS positioning and navigation technology is divided into military code and civilian code. The civilian code is currently open to commercial use. The technology is in the hands of others. If the other party adopts some interference methods under some special circumstances, it will cause positioning inaccuracy or drift. It has become an uncontrollable factor for Chinese enterprises." Haro Travel R&D director Shen Peng said that Beidou is a technology with completely independent intellectual property rights in China and a "own" product. In terms of stability and reliability, such problems will be easily solved before. , So Haro Travel integrated Beidou's receiver chip module into the smart lock as early as 2017. I want to wait until the time is right to enable it. "To be honest, we really did not expect this day to come so fast!" Shen Peng proudly told reporters.

　　Based on this feature, products around the world have an additional positioning system option, that is, the module has both GPS and Beidou. Usually the two systems are used together. When one system fails, the other can be used as a supplement. Stability and reliability are greatly improved.

　　It is understood that due to its complete independent intellectual property rights, the Beidou system has greatly reduced the application cost of positioning and navigation in the country. The price of satellite navigation receivers and other related devices based on self-designed chips has been greatly reduced. By the end of 2019, the sales of basic products such as domestic Beidou navigation chips and modules have exceeded 100 million. In the future, we will see more products using Beidou technology.

More precise positioning

　　High positioning accuracy is a major advantage of the Beidou system. Due to the increase in the number of satellites and the ground-based enhancement system, the positioning capability can be improved from the previous global range better than 10 meters and the Asia-Pacific region better than 5 meters to static centimeters and dynamic decimeters. level.

　　What impact will this feature bring to all walks of life?

　　On the afternoon of July 6, there was a landslide in Leijiashan, Panping Village, Changde, Hunan, which caused a landslide of more than 1 million cubic meters. However, Shimen County received an orange warning of geological disasters from the Beidou satellite monitoring system in advance, bringing all 14 households and 33 people in advance. No one was injured or killed.

　　During the epidemic at the beginning of this year, it was with the help of the Beidou satellite navigation system's high-precision positioning equipment that the engineers who built the Huoshenshan Hospital were able to complete the measurement tasks quickly and accurately, and bought precious time to save lives.

　　Accurate positioning is a prerequisite for refined traffic operations. "Beidou navigation and positioning have a larger coverage area and small positioning blind spots. The use of Beidou to achieve high-precision positioning is a milestone in the field of travel." said Li Kaizhu, CEO of Haro Travel.

　　At present, Chongqing, Zhengzhou and other cities in China have used Beidou positioning in their public transportation systems to allow the background to accurately grasp vehicle location information and movement trajectory in real time, so as to predict user needs in advance and quickly make vehicle management and dispatch responses.

　　In addition, the disorderly parking of shared travel has become one of the urban governance problems. Beidou's high-precision positioning can help users find cars more accurately and conveniently, and solve common problems such as "cannot find a car" and "cannot return a car". Reduce the misjudgment rate of parking in over-zone and no-parking zones, and guide users to ride in a civilized manner and regulate parking.

The innovation ecology can be expected

　　Both 5G technology and Beidou are the "national weapons" that escort the national economy and people's livelihood, and they have a mutually promoting effect. 5G's large-capacity, high-speed, and low-latency transmission capabilities can provide Beidou with more reliable data services. Taking the transportation industry as an example, it is understood that by the end of 2019, there were more than 6.5 million operating vehicles, 30,000 postal and express delivery vehicles, approximately 80,000 buses in 36 central cities, more than 3200 inland navigation facilities, and 2900 Beidou system is applied to many maritime navigation facilities. After the completion of the Beidou network, the super transmission based on 5G can enable the transportation field to combine intelligent technologies such as big data and cloud computing to achieve more scientific and reasonable management and improve production efficiency. As for smart cities, precision agriculture, artificial intelligence, aerospace and maritime affairs, the arrival of the "Beidou Era" is also opening up an expected innovation ecosystem.

　　The launch of Beidou-3 makes short message communication a unique skill of Beidou-the ability to send information has increased from 120 Chinese characters at a time to 1,200 Chinese characters at a time, and the communication bandwidth has also increased from 500,000 users to 5 million users. , Two-way communication can be realized between user and user, user and central control system.

　　At present, this feature has been favored by many fields, and related research and development have begun. "We can develop some additional value-added services based on high-precision location services and short message communication. Assuming that when a bicycle is accurately positioned near a building, we can push relevant information within this range." Shen Peng said . In addition, this function will make field work, mountaineering, expedition, rescue and other fields more convenient.
