Claim:
1. A method for identifying a position of a receiver comprising an antenna and a signal processing system, in an area of interference, the method comprising: receiving, at an antenna system on the receiver, a first radio frequency signal from a platform, the first radio frequency signal comprising navigation information, the platform being distinct from the receiver; receiving at the receiver and the platform, a second radio frequency signal from a satellite in a global positioning system; measuring, using a time of transmission of the first radio frequency signal, the antenna system, and the signal processing system, such that the signal processing system comprises at least one of: a distance from the receiver to the platform using the first radio frequency signal; measuring, using the antenna system, the first radio frequency signal, and the signal processing system, an elevation angle and an azimuth angle of the receiver relative to the platform to form a number of angles; and identifying, using the signal processing system and the number of angles and a position for the platform, a movement and the position of the receiver via:
