PROBLEM TO BE SOLVED: To provide a position estimation system capable of efficiently updating a position radio map.SOLUTION: A position estimation system for estimating the position of a mobile station with respect to a first stationary station and second stationary station includes: a storage unit for storing a plurality of position radio maps showing the relationship between each of the plurality of positions and the radio field intensity between the first stationary station and/or the second stationary station at each of the plurality of positions; and an update unit for updating at least some of the plurality of position radio maps on the basis of the radio field intensity between the first stationary station and the second stationary station.SELECTED DRAWING: Figure 1 |
