Impact of radio link parameters on the interference resistance of GLONASS consumer navigation equipment

This article examines methods for assessing the immunity of navigation equipment to interference from intentional and unintentional electronic jamming. Particular attention is paid to the spectral characteristics of this interference. The approach is based on probabilistic indicators of the normal operation of radio links during signal fading. An important aspect of the study is consideration of the curvature of the earth's surface, the physical and geographical features of the terrain, and the multichannel reception of navigation signals. The results of the study may be useful in the development of new generations of navigation receivers.
