<p>A method of and an apparatus for determining a position of a movable object are arranged such that a radio wave of a constant frequency is transmitted from the mobile object (S7), the transmitted radio wave is received at each of a plurality of spaced positions which are disposed in an area where the mobile object is movable and a frequency of the received radio wave is detected at each of the positions (S8) and the position of the mobile object is determined based on position data indicating the spaced positions and a frequency deviation of the frequency of the received radio wave detected at each of the positions from the constant frequency (S11, 12, 13). Further, a mobile communication system is arranged such that a radio wave of a constant frequency, which is transmitted from the mobile object (MS), is received at each of a plurality of spaced base stations (BS) which are disposed in an area where the mobile object is movable and a frequency of the received radio wave is detected at each of the base stations (S8) and the position of the mobile object is determined based on the positions of the spaced base stations and a frequency deviation of the frequency of the received radio wave detected at each of the base stations from the constant frequency (S11, 12, 13). <IMAGE></p> |
