Vestigial Signal Defense Through Signal Quality Monitoring Techniques Based on Joint use of Two Metrics

Abstract:	The open nature of the global navigation satellite system (GNSS) civil signals makes them very vulnerable to counterfeit and ill-intended interferences like jamming and spoofing attacks. Spoofing of GNSS signal refers to the transmission of a counterfeit GNSS-like signal, with the goal of deceiving the receiver, making it compute erroneous navigation solutions. In this paper, an evolved version of the signal quality monitoring techniques is presented where a spoofer detection algorithm is discussed. The quality of the correlation function is assessed through the joint use of two metrics which are based on the ratio metric and a pair of extra-correlators in order to detect vestigial signal presence. The results show that the joint use of two provides advantages in the detection of matched-power spoofer attacks.
