PROBLEM TO BE SOLVED: To solve the problem that a cost is increased in a positioning system since receivers of many kinds of radio communication systems are required when the radio communication system of a radio terminal possessed by a user is different concerning a system for estimating the position of a user possessing a radio terminal by radio communication between the multiple receivers and a radio terminal.SOLUTION: A positioning system includes a first radio terminal, a first base station, multiple receivers, and a positioning server. The positioning server estimates the position of the first radio terminal on the basis of radio wave intensity to be received from the respective receivers, each radio wave reception time, and a communication connection time to a web site by the radio terminal. |
