The purpose of the present invention is to provide a position estimation system for improving position accuracy using an information terminal. To this end, provided is a position estimation system configured so as to be provided with a first information terminal having a function of transmitting a wireless signal accompanying identification information, and a second information terminal having a function of measuring the reception strength of the wireless signal, the second information terminal measuring the reception strength of the wireless signal transmitted by the first information terminal. At least one of the first information terminal and the second information terminal measures the movement distance, and at least one of the first information terminal and the second information terminal estimates the relative positional relationship between the first information terminal and the second information terminal on the basis of a change in the reception strength of the wireless signal with respect to the movement distance.

    目的在于提供使用了信息终端的提高位置精度的位置推测系统。为此,提供一种位置推测系统,构成为具备具有发送伴随了识别信息的无线信号的功能的第1信息终端和具有测定无线信号的接收强度的功能的第2信息终端,第2信息终端测定第1信息终端发送的无线信号的接收强度,第1信息终端和第2信息终端中的至少一方测定移动距离,第1信息终端和第2信息终端中的至少一方根据无线信号的接收强度相对于移动距离的变化,推测第1信息终端和第2信息终端的相对位置关系。
