The article discusses a new approach to the detection of GNSS spoofing, based on the use of satellite compass. Comparing the results of measurements of GNSS receivers of compass in two modes (normal mode of GNSS navigation and spoofing mode). The studies have shown, that in mode of spoofing attacks in both receivers of satellite compass we have the equality of coordinates, which in algorithm coordinate definitions, determine mathematical indeterminate form 0/0. This means getting out of the operating status of the satellite compass that can be used as an alarm “spoofing attack” to take appropriate security measures of GNSS navigation.

Satellite navigation systems are widely used in navigation for precise trajectory determination of transport equipment. In this article mathematical models and algorithms have been developed to solve the problems of precision and safety of satellite navigation. One of the problems is spoofing (substitution) – a situation in which a system (hardware, software, etc.) successfully masquerades as another by falsifying data system and performs illegal actions. What is considered in the paper is spoofing detection algorithm based on the analysis of a civil satellite signal generated by the two receivers but instead a fully functional Spoofer GNSS signal repeater was used. This work is intended to equip GNSS users and receiver manufacturers with authentication methods that are effective against unsophisticated spoofing attacks. The work also serves to refine the civilian spoofing threat assessment by demonstrating the challenges involved in mounting a spoofing attack.
