Anti-drone active defense equipment

The abbreviation for anti-drone radio active defense equipment (navigation spoofing device) primarily targets the navigation systems of drones. Drones typically rely on satellite navigation systems like the Global Positioning System (GPS) to determine their position, speed, and flight direction. The navigation spoofing device generates and transmits false navigation signals that closely mimic real satellite signals in terms of frequency and code patterns. When drones receive these spoofed signals, their navigation modules mistakenly interpret them as authentic satellite signals, causing the drones to fly according to the positions and directions indicated by the false signals, thereby deviating from their originally planned flight paths.
