In satellite positioning, the carrier signals of user mobile terminals and geosynchronous orbit satellites are affected by factors such as transmission distance and Doppler shift. In order to improve the positioning accuracy for the user, based on the research on the factors of transmission time and Doppler shift between satellite and aircraft, a method for tracking and positioning the aircraft by using multiple satellites is provided. Technology is of great significance for improving the positioning and search and rescue capabilities in special situations, and better mastery of this technology can also promote the development of related satellite communication systems.
