Model of access to satellite radionavigation system resources under conditions of destructive radioelectronic influence

A mathematical model of unauthorized access to the resources of a satellite radio navigation system under destructive electronic influence has been developed. The concepts of navigation security and navigation error have been clarified, indicators for assessing navigation security have been defined, and a generalized indicator for assessing navigation security based on a probabilistic approach has been formed. The research results can be used in developing transport information and control systems.
