POSITION DETECTION SYSTEM AND POSITION DETECTION METHOD

摘要

Provided is a position detection system with which it is possible to inhibit an increase in system costs and to improve accuracy when detecting the position of a terminal. In this position detection system, a first terminal measures radio waves coming from a wireless connection device or a second terminal, and transmits the measurement result to a position detection server via a wireless connection device. If the measurement result includes information regarding the radio waves from the second terminal, the position detection server estimates that the first terminal is located at the position of the second terminal, which transmitted the radio waves. If the measurement result does not include information regarding the radio waves from the second terminal, the position detection server estimates the location of the first terminal on the basis of reference data, positional information regarding the second terminal, and information regarding the intensity of radio waves coming from a wireless connection device, said information being included in the measurement result.
