Abstract: In order to address the problems that the relevant knowledge points are abstract and difficult to understand, as well as the disconnection between theory and practice in the teaching process of BeiDou navigation and positioning, this paper aims to improve the quality of education and students' comprehensive abilities, takes students as the center, follows the law from theoretical learning to practical application, and constructs a whole-process, systematic and progressive Beidou navigation and positioning virtual simulation teaching method integrating “cognition-exploration-application” with the help of virtual reality technology. The method covers a series of teaching contents, including the principles of Beidou Navigation system, system composition, navigation positioning, range measurement error and elimination, and high-precision digital mapping and applications of RTK. This teaching method can simulate the national Beidou instrument, cultivate students' patriotism, break the limitations of time and space, stimulate students' innovation ability, promote the integration of theory and practice, and improve the quality of education. It is very necessary to cultivate surveying and mapping engineering professionals who are proficient in the knowledge of Beidou Navigation system navigation and positioning and have relevant practical skills.
