Apparatus and method for blocking navigation satellite signal reception with respect to illegal unmanned aerial vehicles

Abstract

An apparatus for intercepting navigation satellite signal reception to an illegal unmanned aerial vehicle includes a navigation satellite position identification unit configured to identify a position of a navigation satellite, a plurality of radio wave interference sources distributively arranged, and a radio wave interference source selection unit configured to selectively activate, from among the plurality of radio wave interference sources, a radio wave interference source at a position symmetric to the navigation satellite based on a current position or flight trajectory of an illegal unmanned aerial vehicle to cause an interference signal to emit, wherein the interference signal causes the illegal unmanned aerial vehicle to generate symmetric interference in a direction of the navigation satellite.
