The invention belongs to the technical field of flight navigation, and particularly relates to a method and system for intelligently selecting a TACAN station through inertial navigation combination correction. The method comprises the following steps: S1, determining a nearest TACAN station in a preset range; s2, acquiring the position information, the TACAN orientation, the TACAN slant distance and the aircraft height information of the TACAN; s3, calculating first longitude and latitude information according to data given by the TACAN station; s4, acquiring second longitude and latitude information given by the inertial navigation system; s5, determining the deviation between the first longitude and latitude information and the second longitude and latitude information; and step S6, judging whether the deviation is smaller than a given value, and if the deviation is smaller than the given value, correcting second longitude and latitude information given by the inertial navigation system based on the deviation in the subsequent flight process of the aircraft. According to the method, the inertial information given by the inertial navigation system in the flight process of the TACAN data correction aircraft can be corrected, so that the navigation accuracy is improved.
