Aiming at the practical problem of high demand for positioning accuracy of terminal equipment,this paper combined with the positioning demand of logistics yard under the warehousing environment of an automobile company,and carried out the research on high-precision data fusion combining 5G cellular network and inertial measurement unit.The data generated by the 5G network is integrated with the accelerometer and gyroscope and other information of the IMU module for positioning.Combined with the advantages of strong anti-interference ability of 5G signal and low cost of IMU module,the 5G data is corrected and displayed on the map using the information of IMU.The positioning is achieved in the area covered by the 5G network and the error is within 0.5 m,and the fluctuation range is stable within 0.2 m.
