GNSS Spoofing Detection for Single Antenna Handheld Receivers

: A spoofing source radiates a set of bogus GNSS signals that can deceive a GNSS receiver such that it outputs an incorrect navigation solution. If the jammer signals are sufficiently plausible then the GNSS receiver may not realize it has been insidiously duped before considerable mission cost has incurred. There are various means of detecting spoofing activity and hence providing effective mitigation methods. In this paper, a novel signal processing method applicable to a single antenna handset receiver for spoofing detection is described. Experimental measurements demonstrate the practical effectiveness of this processing, corroborating the theoretical conjectures.
