“5G + BDS High-Precision Positioning” System Iteration Enabling Location of Lanes

The accelerated development of 5G has brought breakthroughs for the iteration and upgrade of high-precision positioning and navigation technologies. Recently, China Mobile released the world’s largest “5G + BDS High-Precision Positioning” system at the 5G Autonomous Driving Summit. The system will provide high-precision positioning services with accuracy measuring in sub-meters, centimeters, and millimeters in real time through the 5G network and constitutes an accurate all-weather and all-day time and space service system. As a leader of Internet maps, Baidu Map took the initiative in reaching in-depth cooperation with China Mobile to access the “5G + BDS High-Precision Positioning” system, becoming the first map developer in the industry to support China Mobile’s high-precision positioning system for mobile phones of consumers. It will bring high-precision lane navigation services to users with smartphones of mainstream brands. So far, Baidu Map is the only map developer in the industry that has access to all mainstream high-precision positioning signals.

It is understood that the “5G + BDS High-Precision Positioning” system released by China Mobile creatively uses the 5G network to empower positioning services. With this system, many aspects such as the stability and the speed of the positioning signal, the initial positioning speed, and the deployed capabilities of the emitters of positioning signals are enhanced to improve the availability of positioning capabilities, thus effectively guaranteeing the realization of high-precision positioning scenarios such as lane navigation, indoor navigation, automatic driving, and automatic parking. With the cooperation in the field of the high-precision positioning system for mobile phones of consumers, Baidu Map and China Mobile will take the lead in supporting the access of all mainstream high-precision positioning signals and apply them to smartphones of mainstream brands so that users with these smartphones can be the first ones to experience lane navigation products of Baidu Map.

Based on this cooperation between the two parties, Baidu Map will continue to optimize the lane navigation technology and services on top of the original high-precision lane navigation capabilities to upgrade users’ driving experience. With the application of the “5G + BDS High-Precision Positioning” system, Baidu Map will display complex intersections, special markings or scenarios of special lanes in a more refined way during the ride of the user through its lane navigation services, highly restoring the driving environment, reducing the difficulty of understanding the navigation, and guiding the user into the most suitable lane. Meanwhile, to address the pain points of misjudgment between main and auxiliary roads and delayed correction of deviation at intersections, Baidu Map also realizes correction and precise guidance in seconds for drivers on the ramps, main roads and auxiliary roads through its lane navigation services to maximize the accuracy, timeliness and safety of navigation. Besides, Baidu Map also launched a function of real-time observation on the condition of lanes which will provide users with an effective reference for making travel decisions based on more fine-grained real-time road conditions. Currently, this function covers most expressways and urban roads across the country.

With the support of the “5G + BDS High-Precision Positioning” system, Baidu Map’s upgraded lane navigation will soon cover five cities, namely Guangzhou, Shenzhen, Suzhou, Chongqing, and Hangzhou. It will continue to expand across the country in the future. As a next-generation AI map, Baidu Map will continue to integrate advanced technologies, improve product performance, provide users with better location services, and create a more precise navigation experience.
