This paper considers a GPS spoofing detection problem. A GPS spoofing attack attempts to deceive a GPS receiver by broadcasting counterfeit GPS signals. GPS spoofing attacks are very significant since spoofing amounts to intentional interference and the target receiver is not aware of its being attacked by GPS spoofers. We suppose that accelerometers can be used to detect the GPS spoofing signal by...
GPS modernization program offers a new civil signal on L2 band, which together with the legacy L1 C/A drives the development of dual frequency receivers for civil applications. The acquisition of L2C takes much time comparing with that of L1 signal. Under the assumption that the GPS signal is strong enough for detection this paper suggests a fast acquisition method for the dual L1/L2C GPS signals...
