1. A method for navigating a vehicle, the method comprising:

  • detecting, during navigation of a vehicle from a point of origin to a destination, a plurality of signals at two or more receiver elements of a receiver, wherein the receiver is integrated with the vehicle;

    estimating, by a processor of the vehicle during the navigation, an angle of arrival (AoA) for at least two signals of the plurality of signals;

    estimating, by the processor during the navigation, a current position of the vehicle based, at least in part, on the AoA for each of the at least two signals;

    determining, by the processor during the navigation, at least one navigation maneuver for navigating the vehicle from the point of origin to the destination based on the estimated position of the vehicle, wherein the at least one navigation maneuver comprises a steering operation to change a direction of travel of the vehicle, a speed control operation to modify a speed of the vehicle, or a combination thereof; and

    executing, by a propulsion and control system of the vehicle, the at least one navigation maneuver.
