Ukraine Unveils Portable System to Jam FPV Drones

The Ukrainian team Sych Tech has developed a portable electronic warfare module, SYCH-AIR-S, designed to detect and suppress the analog video signal of Jam FPV drones, including interceptor drones.

The developers reveals to Oboronka all system details.

The device can be integrated into both ground and aerial platforms.

According to the developers, the module operates by sequentially scanning the radio spectrum within a specified frequency range. When an active signal is detected, the system automatically retunes the transmitter to the relevant frequency and creates a “dome-shaped” interference for 10 seconds. This is followed by a three-second window for rescan.

According to Sych Tech, this architecture helps avoid continuous jamming across the entire frequency spectrum and enables targeted interference with high power density. It also reduces energy consumption and minimizes impact on friendly communication systems.

The module currently operates on several frequency bands: 1.2 GHz, 3.3 GHz, and 5.8 GHz. Testing is also underway for operation in the 7.2 GHz band.

Depending on transmitter power and environmental conditions, the claimed jamming range can reach up to 2 km.

In addition to suppressing video signals, the system has detection and filtering functions, including the ability to ignore specific channels. The module can operate in both automatic and manual modes and can respond to multiple active signals simultaneously. It also includes video recording capabilities for reconnaissance and verification of the device’s operation.

According to the developers, SYCH-AIR-S is already being used by certain units of Ukraine’s Defense Forces.

The team says it is considering further development of the solution, including the creation of a separate drone detector with signal suppression capabilities.

Sych Tech is a project that began as an initiative by an IT teacher (who also serves as the chief engineer) and has grown into a team developing solutions to counter unmanned aerial platforms. At the same time, the project continues to cooperate with volunteer communities.

In addition to producing devices, the team is working on transferring technologies to the military, enabling systems to be manufactured directly within units. According to the team, establishing production of the modules, which they provide to the military free of charge, was made possible thanks to a grant from the military technology development cluster Brave1.

A fundraising campaign by the volunteer team Donating now is currently underway for SYCH-AIR-S modules for units of the Main Intelligence Directorate, the 155th Mechanized Brigade, and the 12th Azov Brigade.
