【Abstract】High‐precision indoor positioning technology is of great significance to the development of national economy. In recent years, with the increasing demand for location services and the continuous iteration of technology, indoor positioning continues to develop towards high precision and seamless. In the case that the satellite signal cannot cover the indoor, the high‐precision indoor positioning technology has become a research hotspot, and a variety of positioning sources and corresponding positioning principles have been developed. Aiming at the latest development status of high‐precision indoor positioning technology, we divide into high‐precision positioning methods based on geometric relation, fingerprint matching, incremental estimation, and quantum navigation according to different positioning principles. We introduce the positioning principle of various methods, discuss and analyze the current technology development, summary the characteristics of high‐precision indoor positioning technology, and discuss the future development trend of multi‐source, intelligent and popular. Through the analysis of different positioning principles and technologies, it has reference value for the future study of indoor high‐precision positioning sources and fusion positioning methods of different positioning sources.
