Abstract: Disclosed are an anti-drone method using a GPS spoofing signal and a system thereof. According to an embodiment of the inventive concept, an anti-drone method may include injecting a GPS spoofing signal to analyze a drone feature of a target drone and hijacking the target drone by injecting a GPS spoofing signal into the target drone based on a drone hijacking strategy corresponding to the analyzed drone feature among predefined drone hijacking strategies. The analyzing of the drone feature may include injecting the GPS spoofing signal to analyze a safety device mechanism (GPS fail-safe) and a path-following algorithm of the target drone.

Abstract: A method for detecting a GPS spoofing attack using a difference between output values of a GPS receiver, which is generated due to inaccuracy of a GPS spoofer, and an apparatus therefor are provided. The method includes receiving a GPS signal; and determining the received GPS signal as a GPS satellite signal or a GPS spoofing signal using a learning model learned based on a difference between output values of a GPS receiver. The method further includes labeling and collecting dispersion degree data including a position, a speed, and a time output from the GPS receiver with whether the GPS signal is the GPS satellite signal or the GPS spoofing signal and modeling the learning model using the collected data.
