EN Jamming and anti-jamming technologies have become an important research topic within the GNSS discipline. While many GNSS receivers leave large space for signal dynamics, enough power space is left for the GNSS signals to be jammed. The goal of jamming is adding a noise to the satellite signal and fooling the receiver not to use signals plus noise for positioning calculations. The goal of spoofing is a falsification of the satellite signal and fooling the receiver to generate a false position; thus, misleading the navigator. This article discusses the experimental approach to anti-jamming and anti-spoofing based on the shielding of the antennas from the jammers and spoofers signals to develop an algorithm for the built-in protection system. In experimental studies, we used two types of screens: the metal funnel and the system of metallic concentric rings on a metal substrate. We also briefly consider the commercial civilian and military jammers. The presented algorithm enables the development of an integrated vehicle safety system.
