ABSTRACT:
A method of avoiding near-far interference problems in a cellular ray of navigation signal beacons having selected CDMA or GPS-like navigation signals. The navigation signals from adjacent navigation signal beacons are pulsed so that adjacent navigation signal beacons do not broadcast navigation signals simultaneously and the multiple frequencies are coordinated in a time divisional multiplex manner. In another aspect, the near-far interference problem is avoided by using multiple frequencies in time division multiplexing and coordinating the use of the multiple frequencies and the time division multiplexing to assure avoidance of the near-far interference problem.
