Modeling and analysis of probabilistic characteristics of the functioning of low-channel equipment of consumers of global navigation satellite systems in conditions of signal-like interference

Abstract

Formulation of the problem. A promising area of research in the field of functioning of navigation equipment for consumers of global navigation satellite signals is the development of protection of consumer equipment from the effects of simulated interference. The high availability of navigation signals of the open segment entails the threat of covert influence on consumer equipment. To date, protection measures against covert interference have been developed and applied for multi-channel consumer equipment with high computing capabilities. However, for low-channel consumer equipment, the development of such protection measures is required, for which it is necessary to determine the probabilistic characteristics of the functioning of the equipment under study under the influence of signal-like interference. Purpose. Determination of the probabilistic characteristics of the operation of multichannel navigation equipment for consumers of global navigation satellite signals in a complex interference environment. Results. A model of the functioning of consumer navigation equipment is constructed and mathematically described, the probabilistic characteristics of the functioning of consumer equipment in a complex interference environment are calculated, and the coefficient of effectiveness of signal-like interference is introduced. Practical significance. The results can be used by specialists in the field of satellite radio navigation in the development of protection systems against covert intentional exposure.
