Beidou system achieves large-scale application in Chongqing: from disaster prevention and reduction to smart campus

China News Service, Chongqing, September 24 (Reporter Liu Xian) Disaster prevention and reduction, shared travel, industrial development, smart campus management... Beidou is being applied on a large scale in Chongqing and is accelerating from "a national weapon" to "thousands of households".

At the Chongqing Beidou large-scale application pilot city construction status press briefing held on the 24th, reporters obtained the above information.

Beidou short message service helps disaster prevention and reduction

Short message communication is a unique and important capability of the Beidou system, and it is also an important support for emergency support in extreme urban scenarios.

Xu Yan, senior business manager of China Space-Time Information Group Chongqing Co., Ltd. (in preparation), introduced that China Space-Time has jointly launched the three major operators of Chongqing Volkswagen Beidou short message service. In the disaster prevention and reduction work during this year's flood season, Beidou short message service was launched for the city's more than 26 million mobile phone users, providing satellite emergency communication guaranteed capabilities. It can realize danger reporting, location reporting, and help information transmission under extreme disaster conditions such as power outages, network outages, and circuit interruptions, effectively building the city's emergency communication defense line, and enhancing urban disaster defense and people's livelihood protection capabilities.

High-precision positioning reduces the rate of random parking of shared electric bicycles

Shared electric bicycles in the Western Science City Chongqing High-tech Zone have a large scale and a high proportion, and have become a key area for Beidou's large-scale application.

Lu Lu, a member of the Party Leadership Group and Deputy Director of the Reform and Development Bureau of Chongqing High-tech Zone, introduced that locally, Meituan has comprehensively promoted the integrated innovative application of "Beidou high-precision positioning + urban refined governance + mass consumption field". The car is equipped with a Beidou high-precision positioning chip, which supports Beidou independent positioning. The static positioning accuracy is ≤30 cm and the dynamic positioning accuracy is ≤50 cm.

The road end builds a digital map based on Beidou's high-precision signals to achieve precise management and control of "sale entry settlement and exit warning".

A smart operation and management platform is built in the cloud to realize real-time vehicle location monitoring, trajectory playback and AI-driven intelligent scheduling.

Lu Lu said that by 2025, Meituan will fully achieve high-precision positioning coverage of more than 10,000 shared electric bicycle terminals. Since its operation, the positioning accuracy has been improved from the 10 meters of traditional GPS to within 30 centimeters, and the rate of random parking has been significantly reduced, providing a replicable and popularized solution for urban slow traffic construction and digital governance.

Beidou empowers smart campus management

Campus safety has always received widespread attention from all walks of life.

Shen Kaixuan, technical director of Ciyuansi (Chongqing) Artificial Intelligence Technology Co., Ltd., introduced that the company is exploring and practicing Beidou applications in the field of smart campus management. The core idea is to use the precise positioning capabilities of the Beidou system as the digital sensing base of the smart campus, and combine it with self-developed education large models and intelligent analysis algorithms to create an integrated smart campus solution of "positioning sensing + data intelligence + scenario application + home-school collaboration" to promote the upgrade of campus management from traditional experience-driven to digital intelligence-driven.

For example, in the comprehensive campus security scene, relying on Beidou's sub-meter positioning and space-time trajectory capabilities, combined with smart wearable bracelets, a multi-dimensional active prevention and control system is built. For campus water safety and key area risk prevention scenarios, electronic fences can be used to achieve second-level early warning of risk areas; for campus conflict hazards and abnormal gathering scenarios, combined with spatio-temporal characteristics such as abnormal location gatherings and long-term stays in remote areas, linked AI behavior analysis can automatically identify conflict risks.

Beidou is deeply integrated into Chongqing’s industrial development

Chongqing is the "Motorcycle Capital of China" and its motorcycle output will rank first among all cities in the country in 2025.

Chongqing Jiuzhou Xingyi Navigation Equipment Co., Ltd. has built Beidou-based intelligent central control, intelligent instruments, active safety and other products and solutions covering the entire range of motorcycles. Li Jun, deputy general manager of the company, said that it has relied on Beidou technology to implement intelligent functions such as positioning and tracking, remote vehicle control, collision warning, blind spot monitoring, riding status monitoring, and cornering ABS to empower vehicle intelligence and safety with technology.

Chongqing Institute of Metrology and Quality Inspection has established two national-level platforms, Beidou Satellite Navigation Product 2502 Quality Inspection Center and National Time and Frequency Measurement Center Chongqing Application Center, which can provide authoritative, standardized and traceable testing services for Beidou and satellite Internet products.

Zhang Wen, deputy director of the institute, revealed that based on the existing Beidou testing platform, Zhengzhou is preparing to build the Chongqing Satellite and Inertial Navigation Industry Measurement and Testing Center with high standards, expanding the testing capabilities from a single satellite navigation to a "satellite navigation + inertial navigation" combined system and key inertial devices such as accelerometers and gyroscopes to provide enterprises with full-chain measurement testing and calibration verification services.

As the only municipality directly under the Central Government to include Beidou large-scale application pilot cities in the construction of the whole region, Chongqing has included Beidou large-scale application and the development of spatio-temporal information industry into the "15th Five-Year Plan". Tang Shouyuan, a member of the Party Leadership Group and Deputy Director of the Chongqing Municipal Economic and Information Commission, said that the next step will be to continue to promote the large-scale application of Beidou and bring Beidou into campuses, communities, and people's lives.
