The solution to the problem of detecting the fact of setting up spoofing clutters to satellite radio navigation
systems by comparing navigation information from consumer equipment and auxiliary inertial navigation
system is considered. The aim of the work is to develop a mathematical model that implements the
simulation of navigation data from each of the systems, and to compare them with decision threshold. Geometrical
formulation of the problem and the algorithm to make a decision on setting up spoofing clutters are
presented. Mathematical modeling has been performed for the trajectory of the object with consumer navigation
equipment in ascending spiral with constant linear speed for the time interval of 120 sec length.
Key words: satellite radio navigation systems, spoofing clutters, inertial navigation systems, microelectromechanical sensors, Euler angles, quaternions, Kalman filter.
