Abstract: An apparatus for recognizing the location of a terminal based on a radio fingerprint map corrects a radio pattern received by a user terminal based on a difference in reception sensitivity between a reference terminal serving as a reference for the creation of a radio fingerprint map and the user terminal, and estimates the location of the user terminal by comparing the corrected radio pattern of the user terminal with the radio patterns in the radio fingerprint map.

Abstract: Provided are a method for determining a moving direction of a terminal and correcting a position thereof, and a positioning apparatus using the same. Relative direction information is estimated based on N pieces of position information of the terminal, and distortion information is removed from the relative direction information to acquire relative direction information without direction integrity. Further, the relative direction information is transmitted into absolute direction information to acquire a moving path direction of the terminal. Next, the position information of the terminal is corrected based on the moving path direction of the terminal.
