The Russian Repellent-1 electronic warfare system is a system designed to guide and jam drone signals.
The jamming range is from 200-6000MHz.
The guiding range is 30 km.
The maximum jamming range is 30 km.
The viewing angle is 360° horizontally
The maximum error in orientation is 3° horizontally
The width of the jamming lobby (the jammer is in the form of a cone whose top is the antenna of the system and whose base is the end of the range): 25° vertically and 125° horizontally.
The system operates in the following stages:
• Detect and find the direction of signals of UAV data transmission and control systems.
• Track the drone signal and determine the frequency accurately.
Determine the azimuth of the location from which the drone control signals come out, in order to rotate the jamming antennas towards the source of the signal, and classify the signals according to their location, distance and source.
• Jamming data transmission channels for drones or jamming the satellite navigation receiver for drones.
The system jams by cutting the signal that reaches the drone and blocks it from it, whether it is from a ground station or a satellite. The wide jamming range from 200 to 6000 MHz includes all GPS frequencies and wireless drone control frequencies.
Mounted on a Kamaz-63501 truck and can be deployed from a mobile to combat mode within 30 minutes. The jamming units are blocks that appear rectangular in shape and each block can be rotated towards the source of the signals.
As we can see in the following picture, there are two masts, the high mast carries signal capture, analysis and locating devices (guidance) with two jamming units, while the short one behind the driver's cab carries rectangular jamming units.
The vehicle can be placed in a trench with a depth of more than 7 meters and the masts raised to the top, which provides protection for the vehicle from hostile fire.
The system inside is controlled by two people.
