Abstract
Systems and methods determine a position using uncoordinated signals containing timing information. The systems and methods use uncoordinated signals of opportunity, such as radio time signals, to determine a position of a receiver by determining the relative synchronization of the signals of opportunity at a known location and, at a later time and unknown locations, using trilateration or multilateration of the signals of opportunity to determine the position of the receiver.
