PROBLEM TO BE SOLVED: To provide a server computer and a positioning system that improve positioning accuracy for locating the position of a walking body in an environment not allowing a GPS to be used.SOLUTION: A server computer 3 sets a point on a map where a terminal 111 for detecting walking information on the walking exercise of a walking body 101 passes through together with the walking body as a position of positioning reference, and is connected with a radio reference station 2 that performs radio communication with a terminal passing through the reference position via a communication network 4. The server computer comprises an information acquisition unit, a position estimation unit, a storage unit 31, a proximity determination unit 35, and a position update unit 36. The proximity determination unit determines whether or not a terminal is situated in a preset proximity distance range on the basis of radio wave intensity between terminals obtained from each terminal. The position update unit updates the position of a terminal in the proximity in the storage unit using the estimated position of the terminal which is determined to be situated in the proximity distance range by the proximity determination unit.SELECTED DRAWING: Figure 2 |
