The prosperity of artificial intelligence and 5G has continuously enhanced the capabilities of edge devices. Edge computing is one of the key technologies of 5G network in the future, and the positioning capabilities of edge devices can significantly expand application scenarios of edge computing. A series of new technologies introduced by 5G can not only meet the needs of communication but also improve the positioning accuracy and achieve ubiquitous positioning. However, 5G base stations and

... vices are far from popular, and the standards of 5G positioning has not fully formed. Thus, simulation is the main research method for studying 5G positioning. Accordingly, we propose a 5G positioning simulation experiment scheme. We mainly introduce the implementation ideas and the specific processes of the simulation experiment of three key parts including scene generation, signal propagation simulation and position estimation. Based on this, we conduct a preliminary study of integrated navigation of inertial measurement unit (IMU) and 5G positioning. Then, we verify the abilities of 5G simulation environment by experiments and discuss the results.
