|Abstract:||We present a method to detect intentional ranging errors on GNSS measurements. Intentional ranging errors can be introduced by targeted radio interference, or spoofing, and are considered a significant threat to aviation safety. The proposed method assumes a functioning APNT capability, able to provide RNP 0.3 or equivalent services independently of GNSS. We present two variants of the method, one in snapshot processing and one in batch processing, where the APNT capability is assumed to include inertial hybridization. The method, after inertial integration, is capable of detecting range errors in the order of 300 m.|
