GNSS Spoofing Detection Based on Signal Power Measurements: Statistical Analysis

Figure 1

Hypothetical stand-off spoofer scenario in an urban canyon. The contours represent the random average spoofer signal power. The average authentic signal power is approximately constant over the entire area given that the receiver-satellite range is approximately unchanged and hence the pathloss.
