An electronic apparatus includes communication circuitry and processing circuitry. The communication circuitry receives first and second wireless signals from a first terminal when the electronic apparatus reaches first and second measurement points. The communication circuitry receives third and fourth wireless signals from a second terminal when the electronic apparatus reaches third and fourth measurement points. The processing circuitry estimates one or more first candidates of a position of the first terminal and one or more second candidates of a position of the second terminal. The processing circuitry specifies the position of the first terminal and the position of the second terminal.
