Abstract: Techniques for detecting and excluding spoofed Global Navigation Satellite System (GNSS) signals are described. Using position data acquired from inertial sensors, a line of sight (LOS) estimation can be determined to various satellites. This data can be compared with range data provided by a GNSS receiver, for example, by subtracting the LOS estimations with corresponding GNSS ranges. The difference can then be compared to an appropriate threshold to determine whether GNSS spoofing is present. Additionally, the non-spoofed GNSS signals can be used to generate an updated position solution, which is verified by an integrity algorithm. If verified, the updated position solution can be used to calculate the position of the vehicle. However, if not verified, the disclosed techniques can adjust the thresholds used to determine GNSS spoofing and perform additional iterations of integrity monitoring to acquire a verified positioning solution.
