The present invention relates to an unmanned aerial vehicle and a method for determining GPS signal spoofing. The method according to the present invention comprises the steps of: capturing current ground images using a camera mounted on an unmanned aerial vehicle; comparing the current ground image with a ground image included in map data in an image-based location estimation part to estimate the location of the unmanned air vehicle; and determining whether the GPS signal is normal by comparing the location estimated by the GPS location estimation part with the location estimated by the image-based location estimation part using the GPS signal.
