Abstract
A position estimation system includes: a processor; and a storage device. The storage device stores data associating measurement data obtained by a terminal device with a position identifier. The measurement data includes on a measured radio wave data, and data a measured acceleration. The processor specifies a period from when the terminal device acquires the position identifier until the processor determines that a user of the terminal device has moved; uses training data including the measurement data obtained by the terminal device during the specified period and the position identifier corresponding to the measurement data obtained by the terminal device to create a position estimation model that outputs the position identifier as a position estimation result when the position estimation model receives the measurement data; and when the processor receives the measurement data, estimates a position of the terminal device by using the measurement data and the position estimation model.
