Abstract: Spoofing jamming to GNSS receivers is a coherence technique for implementing conduct effective jamming with relatively lower transmission power. All the documents published only qualitatively describe that the spoofing signal could induce tracking loops of target receivers with some higher power without quantitative analysis. By modeling receiver tracking loops, the signal power condition of successful induction for the target receiver is analyzed in this paper. Software receiver simulations and real navigation receiver experiments results have demonstrated the validity of the quantitative analysis conclusion.
