Abstract. The article presents research of the possibility of detection of interference in the range of satellite navigation systems by means of additional functional blocks as part of the GNSS receiver. The most dangerous interference, spectrally-coherent interference (spoofing) are considered as interfering influences. GNSS receiver on promising software defined radio (SDR) technology has been chosen as the object of the research.

Key words: SDR, GNSS, GNSS receiver, anti–interference, noise immunity, radio rejection.
