Modern armed conflict and security challenges require high-tech tools to counter aerial threats. Unmanned aerial vehicles (UAVs) and FPV drones are actively used for reconnaissance, attacks, and surveillance. Their deployment demands immediate response and neutralization. The most effective solution today is a portable electronic warfare (EW) system — a device capable of jamming control, navigation, and data transmission channels of a drone.
Purpose and Functions of Portable EW Systems
Portable electronic warfare systems are designed to rapidly and precisely disrupt radio-frequency channels used to control drones and UAVs. These systems can generate directional jamming signals, disrupt radio communication, suppress navigation signals, and block video feeds used for FPV targeting.
Key functions include:
- Suppression of GPS/GLONASS navigation;
- Jamming of radio control channels;
- Disruption of FPV video transmission;
- Destabilization of UAV autopilot systems;
- Providing tactical-level airspace control.
How a Portable EW System Works
The operating principle of a portable EW device is based on emitting radio-frequency interference within specific frequency bands. The system targets frequencies typically used by hostile drones — usually 2.4 GHz, 5.8 GHz, GPS frequencies (L1, L2), and UHF/VHF ranges. Upon activation, the EW device generates electromagnetic noise, causing the drone to lose connection with its operator, interrupt the video feed, and disable its navigation systems.
Advantages of Using Portable EW Systems
Portable EW solutions offer several critical tactical benefits:
- High mobility: Compact size and low weight allow the system to be used anywhere without the need for complex deployment.
- Broad-spectrum interference: Capable of simultaneously jamming multiple frequency bands — including control signals, telemetry, and navigation.
- Versatile application: Suitable for combat operations, protection of strategic facilities, VIP security, and counter-signal intelligence operations.
- Rugged design: Durable casing resists impacts, vibrations, and adverse weather conditions.
Why FPV Drones Are Especially Dangerous
FPV (first-person view) drones are one of the most dangerous UAV types, as they are controlled in real-time via radio signals and transmit live video to an operator’s goggles or monitor. These drones are often used for precision strikes and reconnaissance. A mobile EW system can disable the control and video channels within seconds, depriving the operator of navigation capabilities.
As a result, the drone may hover, crash, or return to its launch point — depending on its software.
More advanced drones equipped with autopilots use satellite navigation to complete missions. Portable systems effectively jam GPS and GLONASS signals, disabling their navigation equipment. In such conditions, the UAV may lose orientation, deviate from its course, or fail to complete its objective.
Jamming is performed at frequencies of 1575.42 MHz (GPS L1) and 1227.6 MHz (L2), ensuring reliable neutralization of the aerial threat.
Types of Portable EW Systems
Portable electronic warfare systems can be categorized by their effective operational range:
- Short-range EW systems: Operate within a radius of up to 500 meters. Used to protect convoys, patrols, checkpoints, and VIP movements. Compact and quick to deploy, they are ideal for mobile tactical teams.
- Long-range EW systems: Capable of jamming signals over distances exceeding 2,000 meters. Used to protect infrastructure, command posts, warehouses, and communication antennas.
Areas of Application for Mobile EW Systems
Mobile EW systems are relevant for:
- Military units at the frontlines and in rear areas;
- Border protection and monitoring of frontier zones;
- Critical infrastructure facilities (airports, power stations, logistics hubs);
- Security firms and special forces units;
- Executive protection services during official duties.
In addition to combating drones, portable jamming systems effectively protect against surveillance and data leaks. By disrupting communication and data transmission channels, they prevent remote eavesdropping, data interception, or interference with local networks.
