NAP GNSS INTENTIONAL INTERFERENCE DETECTION METHOD Russian patent published in 2018 - IPC G01S7/36 H04K3/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to the radio engineering, and, in particular, to the intentional interference detection methods by the global navigation satellite system (GNSS) consumer navigation equipment (CNE). This result is achieved due to the fact that in the intentional CNE GNSS detection method, interference signals are detected, generated by of false navigation signals generators (FNSG) in the GNSS system, conducting, at the first stage, the analysis of directions to the received signals sources and interference, highlighting the received signals, coming from one direction and having different navigation coordinates, including them to the interfering signals coming from the FNSG, at the second stage – analysis of the received signals and interference amplitudes (levels), highlighting the signals with amplitudes significantly different from the useful signal estimated amplitude, including them as interfering signals coming from the FNSG, at the third stage – analysis of the navigation messages content in the received signals for belonging to the navigation satellites national group on the basis of a priori data on the received signals group and interference, highlighting the signals, having irregularities in structure and content, including them as interfering signals coming from the FNSG.

EFFECT: achieved technical result is the CNE GNSS intentional interference detection by the received from different sources navigation signals analysis.
