With the increasing complexity of electromagnetic environment and increasing intensity of military confrontation, the potential security exposure in the application of satellite navigation has become one real threat to face. This paper has an analysis on GNSS repeater spoofing technique, for fake Position, fake Time and fake Velocity in theory. The analysis results of this paper will provide beneficial guidance for the development of spoofer. Besides, the spoofing technique and anti-spoofing technique are like lance and shield. The progress on spoofing technique will also promote the development of anti-spoofing technique.
