METHOD FOR POSITIONING BASED ON WEIGHTED TRIANGULATION AND METHOD FOR INDOOR POSITIONING USING THE SAME

摘要

A weighted triangulation according to an embodiment of the present invention may include the steps of: measuring each of reference signal strength indications (RSSI) of wireless signals respectively received from at least three stationary base stations; estimating each of estimated distances from user terminal to each of the stationary base stations on the basis of the measured RSSI values; determining each of weighted values with respect to each of vertexes of an overlapping area when the overlapping area is deducted by overlapping virtual circles each of which has a center at each of installation positions of the stationary base stations and a radius of each of the estimated distances; and calculating a weighted center of gravity of a polygon formed by the vertexes of the overlapping area using the weighted values to determine the weighted center of gravity as a position of the terminal.
