Us military develops RF signal jammer for uav

With drone sales expected grow exponentially in the near future, and an increasing number and severity of drone incidents occurring daily, DroneShield launched DroneGun to respond to nefarious use of consumer and commercial drones and the resulting need for effective countermeasures to drone intrusions. DroneShield aims to help public and private sector customers, where allowed by law, take proactive measures against airborne threats to safety, security, and privacy.

In contrast to the portable hand-held jammers, why do we want to choose desktop drone jammer? The reason is simple, hand-held jammer main advantage is small and portable, the advantages of the desktop jammers is mainly interference with the frequency band, a large range of interference, and the interference signal is more stable and more reliable.

When a drone is hit with a jammer’s signal, the drone usually returns back to its origin point (unless GPS is also jammed), giving the jammer user the option to track the drone back to the pilot. Sometimes the drones might even perform a vertical descent and land on the spot intact, which offers the option of performing a forensic investigation. Landing on the spot is also the general response from drones when both RF and GPS are jammed at the same time.

With a large interference range of 70 meters, can cover a whole classroom or medium-sized room. Can be used for educational institutions, churches, cinemas and other places that need to remain quiet.

The Russians began jamming some smaller U.S. drones several weeks ago, the officials said, after a series of suspected chemical weapons attacks on civilians in rebel-held eastern Ghouta. The Russian military was concerned the U.S. military would retaliate for the attacks and began jamming the GPS systems of drones operating in the area, the officials explained.

According to Perfectjammer, Perfectjammer Labs is selling its portable drone jammer to the Department of Defense and Department of Homeland Security. The wifi jammer, which looks like a cross between an old-school TV antenna and an assault rifle, can stop drones more than 400 yards away.
