Disclosed are an anti-drone method using a GPS spoofing signal and a system thereof. According to one embodiment of the present invention, the anti-drone method comprises the steps of: injecting a GPS spoofing signal to analyze a drone feature of a target drone; and hijacking the target drone by injecting the 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 step of analyzing the drone feature can include a step of injecting GPS spoofing signal to analyze a safety device mechanism (GPS fail-safe) and a path-following algorithm of the target drone. Therefore, the present invention is capable of effectively hijacking a drone which has invaded within a certain area.

    GPS 기만 신호를 이용한 안티 드론 방법 및 그 시스템이 개시된다. 본 발명의 일 실시예에 따른 안티 드론 방법은 GPS 기만 신호(spoofing signal)를 주입하여 대상 드론의 드론 특성을 분석하는 단계; 및 미리 정의된 드론 납치 전략들 중 상기 분석된 드론 특성에 대응하는 드론 납치 전략에 기초하여 상기 대상 드론에 GPS 기만 신호를 주입함으로써, 상기 대상 드론을 납치하는 단계를 포함하며, 상기 드론 특성을 분석하는 단계는 상기 GPS 기만 신호를 주입하여 상기 대상 드론의 안전장치 메커니즘(GPS fail-safe)과 경로 추종 알고리즘(path-following algorithm)을 분석할 수 있다.
