Abstract
A receiver processes Global Navigation Satellite System (GNSS) signals transmitted from satellites and non-satellite signals transmitted from beacons. The receiver comprises an adaptive despreader configured for adaptively despreading a channelizer output signal-to extract received navigation signals and generate baseband symbol data therefrom. The channelizer output signal comprises channelized received navigation signals, each comprising a spreading code that repeats every baseband symbol. A copy-aided analyzer is communicatively coupled to the adaptive despreader and configured for determining geo-observables from the baseband symbol data of at least one received navigation signal. A positioning navigation and timing (PNT) computation element is communicatively coupled to the copy-aided analyzer and configured for employing the geo-observables to differentiate between the at least one received navigation signal and at least one signal transmitted by at least one of a GNSS satellite, a spoofer, a jammer, a beacon, a repeater, and a pseudolite.
