Abstract
A position detection system is provided which is capable of inhibiting an increase in system costs and improving accuracy of detecting a position of a terminal. In the position detection system, a first terminal measures radio waves from a wireless connection device or a second terminal, and transmits a measurement result to a position detection server through the wireless connection device. The position detection server estimates that the first terminal is located in a position of the second terminal which has transmitted the radio waves in a case where the measurement result includes information of the radio waves from the second terminal, and estimates the position of the first terminal based on information of radio wave intensity of the radio waves from the wireless connection device, which is included in the measurement result, reference data, and positional information of the second terminal in a case where the measurement result does not include the information of the radio waves from the second terminal.
