Instantaneous Radiolocation Using AM Broadcast Signals

Timothy D. Hall, Charles C. Counselman III and Pratap Misra

Abstract:	Carrier-phase measurements of AM broadcast radio signals yield unambiguous, instantaneous, determinations of relative position vectors. Continuous tracking is not required. Integer cycle ambiguity is resolved as in GPS geodetic surveying, but much more robustly because so many AM radio stations are available. Meter-level accuracy is obtained over distances of several hundred meters, and should be obtainable over much greater distances.
