Spoofing and antispoofing algorithms have become an important research topic within the GNSS discipline. The power of the GNSS signal on the earth’s surface averages –160 dBw. While many GNSS receivers leave large space for signal dynamics, enough power space is left for the GNSS signals to be spoofed. The goal of spoofing is to provide the receiver with a misleading signal, fooling the receiver to use fake signals in space for positioning calculations. The receiver will produce a misleading position solution. The purpose of this paper is to analyze the vulnerability of the satellite signal in repeater’s output from the viewpoint of GNSS spoofing attacks. The article discusses a new approach to GNSS spoofing, based on the application of GNSS signals repeating by potential terrorists. Practical spoofing that provides misleading navigation results at the receiver is difficult to conduct due to the signal infrastructure, and by applying trivial anti-spoofing algorithms in GPS receivers, spoofing attack can be easily detected. To detect spoofing attacks of this type we have a variety of methods. For example, the authors suggest the use of paired navigators and GNSS compasses as detectors of GNSS spoofing.
