High-precision positioning has become a rigid requirement for intelligent driving. Qianxun Location has built the world's largest GNSS augmentation station network

For advanced intelligent driving above L2 level, high-precision positioning has become a necessary condition. According to the operating logic of self-driving cars, the vehicle needs to determine its own position before it can solve the problem of how to reach its destination. In some special scenarios, such as urban canyons, elevated roads, tunnels, underground garages, etc., the vehicle's positioning accuracy requirements must reach the centimeter level, while having sufficient high availability to ensure driving safety. To this end, Qianxun Location has established more than 5,000 GNSS enhancement stations worldwide.
