What is a drone jammer?

Signal jammer are also called signal blockers. They are devices that block radio communications signals. A pilot on the ground remote-controls an Unmanned Aerial Vehicles (UAV). Therefore, blocking the radio signal renders a UAV useless. The drone will either fall to the ground or land, depending on its programming.

The jammers “had a pretty significant impact” on UN surveillance drones, which were grounded for days after gathering intelligence from the air. American military officials would not say whether the latest jamming has caused drones to crash, citing operational security.

But the sources told NBC that Russian’s sophisticated jamming equipment, which was developed by its military, has proved to be effective even against some encrypted signals and anti-jamming receivers.

It’s introducing the DroneGun, a GPS signal jammer that disables drone signals (including GPS and GLONASS positioning) from as far as 1.2 miles away. Like most rivals, it doesn’t destroy the target drone — it just forces the vehicle to land or return to its starting point. Anti-drone teams can not only disable threats from a safe distance, but potentially locate their pilots.

Most current Perfectjammer jammers use a wider jamming signal across a range of frequencies, whereas BEAM is configured to detect a specific single frequency used by an attacking drone – a solution particularly suited for urban or more populated combat areas.

U.S. analysts first caught the Russian military jamming drones in eastern Ukraine four years ago, after the invasion of Crimea, according to Humphreys. He said the jammers were initially detected as faint signals from space, bouncing off the earth’s surface. The jammers “had a pretty significant impact” on the United Nations surveillance drones that were attempting to monitor the area, grounding the fleet for days and halting intelligence gathering from the air.

The Drone jammer works by directing radio energy at the drone, disrupting the remote control link between the drone and the operator. The jammer operates at common industrial, scientific, and medical (ISM) frequency bands. 2.4 GHz, one of the most common drone control frequencies, is part of the ISM band.
