Beidou and big data combined with space technology make travel more green and efficient.

CCTV News:Now, with the global networking of Beidou, our navigation software not only uses our own satellites, but also brings more functions and better experiences to our travel life.

According to the latest data, among the mainstream mobile navigation software in China, Beidou system has surpassed GPS system in many dimensions, such as the average number of satellites called in a single positioning and the civil positioning accuracy, and has officially realized the overall dominance of domestic navigation application positioning. The daily positioning of Beidou satellite called by map software has exceeded 400 billion times, and it can provide more accurate services.

Hong Bo, a map navigation travel expert:This is the real-time traffic light countdown, which can display the countdown of the red light on the map navigation in real time. Users will know how long to wait after seeing it, and their anxiety will be reduced. Now we have entered the lane navigation. We are in the rightmost lane, and we can lean against the middle lane. You can see it. Now we are driving in the middle lane, which is all with the help of Beidou high-precision positioning technology.

Hongbo told reporters that Beidou system is the basis of many innovative travel functions. Combining Beidou with big data can improve the accuracy of road condition prediction, bus arrival time prediction and car congestion, and improve travel efficiency. It can also help alleviate urban traffic congestion through the summary of data.

Hong Bo, a map navigation travel expert:Based on this, the government can do some special treatment, adjust the period of traffic lights in real time according to the current traffic situation, and consider extending the green light time in case of special congestion.

Not only online applications, Beidou system can also be combined with offline products. Some traditional road warning devices have been transformed into new intelligent devices by carrying Beidou chips.

CCTV reporter Wu Tianbai:What I have in my hand is a road safety early warning device with Beidou high-precision positioning chip. When I open this device, I can report the road construction information in real time and display it on the map.

Chief positioning system expert Fang Xing:This kind of compact one is characterized by high positioning accuracy and a positioning chip at the bottom.

Zhao Wei, a staff member of Beidou Intelligent Equipment Team:If the construction has already started, it may be delayed by half an hour if we use the algorithm again. However, through Beidou’s high-precision positioning, the position is very accurate and the timeliness is particularly good.

After three years of application upgrade, Beidou navigation system has been integrated into our lives. The latest data shows that the total output value of satellite navigation and location service industry is about 470 billion yuan. This year, the Beidou system will also launch two supplementary satellites to further enhance the stability and function of the system.
