China's national Beidou high-precision navigation and positioning service platform has consolidated nearly 7,000 base stations into a unified national network, providing high-precision positioning services with millimeter-level accuracy, according to the Ministry of Natural Resources of China.
Launched in 2024, the unified network is a key supporting infrastructure for the operation of the country's self-developed BeiDou Navigation System, offering centralized management of station resources. The network now encompasses 6,951 base stations across China, a significant increase from the 3,363 stations at the project's inception.
Those include 420 national-level stations, 3,093 provincial-level stations, and 3438 coordinating stations.
"We have built a unified network, raising BeiDou's positioning accuracy from several meters to just a few centimeters, and even millimeters. In eastern regions, the average spacing between stations has reached 30 kilometers, while in the west it is about 50 kilometers, forming a relatively uniform spatial distribution. The network now serves nearly 200,000 professional users nationwide," said Zhang Jun, head of the Department of Land Surveying and Mapping under the Ministry of Natural Resources.
The network provides seamless, high-precision positioning services across the country, delivering real-time, accurate and reliable navigation for sectors including public welfare mapping, resource surveying, intelligent transportation, autonomous driving, precision agriculture and social governance.
"Next, we will further refine relevant policies and regulations and enhance data sharing and use to support natural resource management, urban renewal, and emerging sectors such as the low-altitude economy. This will accelerate the industrialization and large-scale application of BeiDou," said Chen.
