Electronic warfare has become a key technology in today’s warfare, especially in countering GNSS (Global Navigation Satellite System) and Unmanned Aerial Vehicles (UAVs). Jamming technology for GNSS signals has evolved from low-cost basic jammers to sophisticated military-grade systems. These systems are designed to disable enemy navigation equipment, block the effectiveness of precision-guided weapons, and protect critical strategic assets and infrastructure. cell phone jammer This article delves into the progress of countries such as Russia, Turkey, and the United States in this area.
R-330Zh Zhitel and Pole-21E: Russia’s Jamming Network
Russia’s R-330Zh Zhitel system was widely used to jam GNSS signals during the war in Ukraine. The Zhitel system not only jams cell phone communications within a range of 25 kilometers, but also disrupts GNSS signals over a wider range, thereby weakening the combat capabilities of drones and GPS missiles. GPS jammer Similarly, the Pole-21E system uses cell phone towers as jamming sites to create a large-scale electronic jamming network through the GSM communication network, which has repeatedly hindered UK drone operations. Wifi jammer The distributed design of the Pole-21E system enables it to block a wide range of GNSS signals through multiple nodes, becoming a key means of protecting Russia's important strategic assets.signal jammer
Tobol system: the mastermind behind European GNSS interference
Another more advanced jamming system is Russia's 14Ts227 Tobol. This system has a wider coverage area and can cause GNSS signal interruption throughout Europe. Although the Ukrainians have repeatedly carried out precision drone strikes on locations such as Kaliningrad where the system is deployed, Tobol still has a huge impact on civilian and military navigation in the Baltic Sea, Scandinavia and even Eastern Europe, especially blocking precision-guided weapons such as drones and cruise missiles.
Turkey's Seymen system: selective jamming and deception technology
Turkey's Seymen system is another important innovation in the field of electronic warfare. As a mobile electronic warfare platform, Seymen can not only selectively interfere with GNSS signals, but also deceive enemy navigation systems while maintaining the navigation capabilities of its own forces. Its system can accurately interfere with targets in multiple directions and different GNSS constellations by installing multiple directional launch modules. Seymen demonstrated Turkey's advancement in NAVWAR (navigation warfare) technology.
The future of drone electronic warfare technology: SRC's Silent Cyclone and Silent Impact
With the widespread use of drones in warfare, electronic warfare capabilities have gradually shifted from fixed-position deployment to mobile and drone-mounted platforms. For example, the Silent Cyclone and Silent Impact systems of the US SRC company, which can be deployed deep into enemy territory by drones or artillery to conduct efficient electronic jamming operations. Silent Impact can even be fired by artillery, allowing the jammer to reach the enemy's rear area, suspended in the air by parachutes, and continuously paralyzed the enemy's navigation system.
