Context: The Defence Research and Development Organisation (DRDO) has developed a comprehensive integrated anti-drone system, focusing on the detection, identification, and neutralization of drones.

  • The anti-drone technology is designed to counter various types of drones, including micro drones, and is suitable for land borders.
  • D4 system can instantly detect and jam micro drones (Soft kill) and use a laser-based kill mechanism to terminate targets (Hard kill).
  • Utilizing the Global Navigation Satellite System (GNSS), it identifies the frequency employed by the controller and subsequently disrupts the signals.
