Abstract: A computing device loads signal strengths of wireless communication signals collected at a plurality of first collection areas and position information of the first collection areas, sets positions of a plurality of virtual transmitting apparatuses. The computing device estimates signal strengths of wireless communication signals in a plurality of second collection areas based on a distance between a position of each of the virtual transmitting apparatuses and each of the first collection areas, a signal strength collected at each of the first collection areas, and a distance between a position of each of the virtual transmitting apparatuses and each of the second collection areas. The computing device determines an optimal virtual transmitting apparatus among the virtual transmitting apparatuses, and generates positioning data at the second collection areas based on signal strengths in the second collection areas which are estimated based on a position of the optimal virtual transmitting apparatus.

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.
