Motivated by the limitations of prior work, we propose a GPS spoofing detection scheme that requires minimal prior configuration and employs information fusion based on the GPS receiver and inertial measurement unit (IMU). We use a realtime model of tracking and calculating to derive the current location of the drones which are then contrasted with the location information received by the GPS receiver to judge whether the UAV system is under spoofing attack. Experiments show that, while the accuracy meets the requirements of detection, the proposed method can accurately determine whether the system is attacked within 8 s, with a detection rate of 98.6%. Compared with the existing schemes, the performance of realtime detecting is improved in our method while the detection rate is ensured. Even in our worst-case, we detect GPS spoofing attack within 28 s after the UAV system starts its mission. 收起
