Abstract
In this paper, we propose a method to detect GPS spoofing signals by using accelerometer and GPS acceleration measurement value in the navigation coordinate system(NED). AHRS is used to compute the attitude information, and the accelerometer measurement value is converted into the navigation coordinate frame and compared with the GPS acceleration measurement value. When there is no spoofing, the threshold value is calculated from the error model for the measured values of the navigation coordinate frame, and the spoofing detection is determined by comparing with the measured value. We also analyze the influence of sensor noise, AHRS attitude error, and body motion on threshold values.
