METHOD FOR DETERMINING STATUS OF UNMANNED AERIAL VEHICLE, UNMANNED AERIAL VEHICLE STATUS DETERMINATION DEVICE USING SAME AND UNMANNED AERIAL VEHICLE STATUS DETERMINATION SYSTEM USING SAME
METHOD FOR DETERMINING STATUS OF UNMANNED AERIAL VEHICLE, UNMANNED AERIAL VEHICLE STATUS DETERMINATION DEVICE USING SAME AND UNMANNED AERIAL VEHICLE STATUS DETERMINATION SYSTEM USING SAME
The present invention relates to a method for determining the status of an unmanned aerial vehicle (UAV), to determine the presence of an external attack and the type of the external attack, a UAV status determination device using the same and a UAV status determination system using the same. According to one embodiment of the present invention, the method for determining the status of a UAV comprises the following steps of, by a central station: receiving an aircraft surveillance signal transmitted from a target UAV and transferred through each of a plurality of relay stations; using the location of each of the plurality of relay stations and information of time when the aircraft surveillance signal is received by each of the plurality of relay stations to determine a first expected location of the target UAV; using location information included in the aircraft surveillance signal to determine a second expected location of the target UAV; determining an external attack on the target UAV in accordance with whether a difference between the first and second expected locations exceeds a reference value; and determining the type of the external attack based on a moving pattern of the second expected location.;COPYRIGHT KIPO 2020
