Countering Spoofing and Improving the Noise Immunity of Consumer Equipment GNSS

The paper discusses ways to improve the noise immunity of the means of coordinate-time and navigation definitions on the basis of global navigation satellite systems (GNSS). The problems of vulnerability of the navigation equipment of user to spoofing influences are considered. Analyzed the measures to detect and counter spoofing attacks new. Shows the results of model studies spoofing attacks based on the modeling unrequesting measurement information.
