Abstract:	With the widely application of Global Navigation Satellite System (GNSS) nowadays, GNSS spoofing attack becomes an unavoidable problem. Various anti-spoofing methods are proposed in recent years, including methods operate in GNSS receivers and methods operate in integrated navigation systems, e.g. GNSS/INS (Inertial Navigation System) system. However, methods operate in GNSS receiver have difficulty in detecting sophisticated spoofing attack, and methods operate in integrated navigation system introduce the risk of misleading the integrated navigation system. In the paper we propose a spoofing detection method making use of raw GNSS measurements and raw IMU measurements. Through utilization of IMU measurements, the proposed method can achieve better performance than methods using GNSS measurements only. In addition, the proposed method operates ahead of the integrated navigation algorithms, which increases the overall robustness. A series of field experiments are conducted and experiment results verify the performance of the proposed method.
