Zusammenfassung:	The present invention is a method and system to mitigate emulator spoofer signals. In an embodiment of the invention, the system of the present invention may be a navigational receiver which may acquire authentic signals in the presence of spoofer signals whereby the authentic navigational signals may be processed to determine a correct position of the receiver. The receiver of the present invention may execute a mitigation method of the present invention whereby characteristics of pairs of signals of received signals may be determined. The mitigation method may also include selection of an authentic signal based upon the characteristics of signal pairs. Characteristics of signal pairs may include relative amplitude, phase and frequency.
