Abstract
Systems, methods, apparatuses and computer-readable storage media for navigating an unmanned aerial vehicle (UAV) using signals of opportunity are disclosed. The UAV may include a receiver for detecting a plurality of signals at two or more receiver elements. The UAV may estimate an angle of arrival (AoA) for at least two signals of the plurality of signals, and may estimate a position of the receiver based, at least in part, on the AoA for each of the at least two signals. Known locations of the transmitters that are transmitting the at least two signals may be used in conjunction with the AoAs to determine the estimate of the position of the receiver. More than two signals may be used to localize the estimated position of the receiver.
