Non-kinetic counter-UAV measures operate by interfering with or intercepting the communication signals of drones. As a result, these methods typically cause the drone to fall rapidly, which makes them an undesirable option in crowded environments. However, they can be effective in other scenarios. It is important to consider the legal stipulations in your country regarding drone countermeasures, as the use of drone jammers and spoofers is not permitted in the United States. Let us review some different non-kinetic C-UAS techniques.
Drone GPS Spoofers
What are drone spoofers?
Jammers impede radio frequency communications, whereas spoofers create artificial GPS signals that closely mirror legitimate signals. By transmitting a misleading signal, spoofers can commandeer the drone’s communication link, leading the device to accept it as a valid signal due to its similarity to the authentic signal.
Spoofers achieve their purpose by sending a more intense fraudulent signal. They can induce a minor delay between the drone and its controller, followed by the transmission of a stronger imitation signal. Consequently, the spoofer acquires control of the device and is capable of operating the drone. Spoofers disrupt GPS receivers.
If your UAS device is dependent on GPS for its flight operations, it poses considerable difficulties in countering GPS spoofing. The GPS signal is emitted by satellites, and it is not possible to incorporate typical protective mechanisms like encryption or certificates into these satellite signals.
What are the disadvantages of using spoofers against drones?
Spoofers have four main disadvantages compared to C-UAS:
Drone spoofing is deemed illegal across numerous countries, with the United States being among them.
Drones that do not utilize GPS are less susceptible to the interference caused by drone spoofers.
Drone spoofers lack the capability to ascertain the position of the pilot or the course of the flight.
By scrambling nearby GPS signals, drone jammers create challenges for authorities attempting to use GPS devices in real emergencies.
Burkina Faso soldiers are now fielding a Chinese-made WRJ-Q02 anti-drone jammer that can force unwanted small commercial drones to land. The anti-drone jammer costs $2,300 per unit.
SOF, GUR, the 78th regiment and battalions of the 80th, fighting in #Kursk area, urgently needs drone jammers, drones, powerbanks, generators, and antennas.
