One type of attack on autonomous vehicles is GPS spoofing, which involves altering GPS signals to deviate from their true values. If this attack succeeds, the autonomous vehicle can be directed to arbitrary locations. The authors have demonstrated that adding a constant signal as a method of shifting the true value is effective in the sense of ikelihood ratio testing. In this study, we experimentally evaluate the effectiveness of this attack and identify the differences between theoretical predictions and experimental results. In the experiment, we construct a system consisting of a robot subject to the attack and a monitoring system using likelihood ratio testing. The attacker’s objective is to guide the robot into a hazardous area. The experiment examines whether the robot can move into the hazardous area while deceiving the monitoring system.
