Abstract

The present technology provides a system and a method for terminal positioning. According to a specific embodiment of the present invention, the position of a terminal is estimated using inner and outer centers obtained through points on each distance circumference generated on the basis of the RSSI of each indoor positioning sensor, a terminal correction position is derived: using an estimated terminal position derived using each distance value generated on the basis of the RSSI of each indoor positioning sensor, and the intersection points between straight lines connecting a circle with the smallest radius determined with the RSSI, the remaining two circles that excludes the circle with the smallest radius, and the estimated terminal position; and on the basis of the circular arc of the smallest circle, including the intersection points, and the ratio of the radii of the remaining two circles that excludes the smallest circle determined with the RSSI, and the estimated terminal position is corrected using the derived terminal correction position so that the accuracy of terminal position can be fundamentally improved.
