A position estimation device which includes: a distance estimation unit which estimates, using a receiving strength of a signal received by a wireless terminal from each of a plurality of base stations communicating with the wireless terminal, distance information indicating a distance from the base station to the wireless terminal; a position estimation unit which estimates a first position to be a current position of the wireless terminal using base station information indicating a position of the base station and the estimated distance information; and a correction unit which corrects the distance information based on an acceleration and a direction of the wireless terminal, the estimated first position, and the base station information. The position estimation unit further estimates a second position to be a current position of the wireless terminal using the base station information and the corrected distance information. |
