Abstract
System and methods of tracking a position of a mobile device with an electromagnetic signal-transmitting antenna include receiving electromagnetic signals from the transmitting antenna of the mobile device by a plurality of receiver antennae of a base station and by one or more receiver antennae of a relay station. The relay station transmits to the base station timing information associated with the electromagnetic signals received by the one or more receiver antennae of the relay station. The base station computes a position of the transmitting antenna of the mobile device based on timing information computed from the electromagnetic signals received by the plurality of receiver antennae of the base station and on the timing information received from the relay station.
