1. An apparatus for intercepting navigation satellite signal reception to an illegal unmanned aerial vehicle, the apparatus comprising:
a plurality of radio wave interference sources distributively arranged; and
one or more processors configured to:
identify a position of a navigation satellite, and
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.
