Abstract:   (666 Views)

Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver. We will study a real-time spoof recognition ‎with a clear certainty by introducing a reliable novel metric. As a primary step, the proposed technique is ‎implemented in software receiver to prove the concept of idea in a multipath-free ‎scenario. ‎Three rooftop data sets, collected in our GPS laboratory, are used in the ‎performance assessment of the proposed method. The results indicate that investigated algorithm is ‎able to perform a real-time detection in all date sets.
