Abstract
The position of a transmission device is estimated with a sufficient accuracy. A position estimation system includes a transmission device that includes a plurality of transmitters arranged symmetrically with respect to a specific reference position, a plurality of receivers that receive radio waves transmitted from the plurality of transmitters, and an estimation tool that estimates the position of the transmission device, based on reception strengths of the radio waves received at the receivers.
