Abstract: With the rapid development of intelligent connected vehicles, high-precision 3D navigation has become a key supporting technology. This article conducted a series of drive tests using the high-precision navigation technology of BeiDou and BeiDou+5G hybrid positioning technology, aiming to verify the positioning performance in complex highway traffic environments. The test was conducted on actual roads in Beijing and Hangzhou showed that the positioning accuracy of BeiDou high-precision navigation reached a real-time centimeter level, with a fixed rate of about 95% and a convergence time of less than 2 s. The elevation accuracy of BeiDou+5G hybrid positioning was better than 0.2 m. Combined with three-dimensional high-precision laser point cloud maps, the overlay verification showed that the model can support three-dimensional lane level navigation, verifying the application potential of BeiDou high-precision positioning and BeiDou+5G hybrid positioning technology in the fields of autonomous driving and intelligent connected vehicles.
