Zala Aero Group, a Kalashnikov company, has presented its REX 1 counter-UAS gun at the Army 2017 forum in Russia. According to the company: “The weapon is equipped with a block of suppression, which drowns in the radius of five kilometers signals of the US satellite navigation system GPS, Russia’s GLONASS, China’s BeiDou and Europe’s Galileo. Also, the device is capable of blocking GSM, 3G, LTE signals at a kilometer distance and interfering with frequencies of 900 Mhz, 2.4 GHz, 5.2 – 5.8 GHz. The REX 1 disables the drone but does not damage it physically – the aircraft loses its connection with the control panel and smoothly lands…To put the device in combat readiness, just press one button. The weapon is equipped with a fastening system, so that it can additionally be equipped with sights, lights, designators, as well as objective control devices….The weight of REX 1 is 4.2 kg, while the model has a built-in battery that provides continuous operation of the device for three hours.”
Russian news agency TASS reported in October that Zala had demonstrated a new device of satellite navigation signal suppression for unmanned aerial vehicles (UAVs) at the Interpolytex-2018 security exhibition.“The compact module is placed under an unmanned aerial vehicle’s wing and suppresses the signal of satellite navigation systems within a radius of up to 5km, and also blocks the operation of all devices that use satellite navigational systems for navigation,” the Kalashnikov press office said.
The satellite navigation signal suppressing system has been developed for Special Operations forces. The system can be used to neutralize an enemy’s equipment that may pose a threat to defended facilities. The new system will expand the range of electronic warfare devices developed by Zala. It comprises the REX-1 anti-drone rifle and the ZONT man-portable device. The new satellite navigation signal suppressing system has undergone successful trials and proven its efficiency.
