Rostec’s subsidiary Rosel has developed a portable passive detection device for unmanned aerial vehicles called “Ogonyok” (Little Flame). The system intercepts video feeds directly from hostile drone cameras, including FPV, DJI, and Autel models. By extracting video streams from radio signals, the device eliminates false target acquisition from Wi-Fi or LTE sources, according to Rostec officials.
Ogonyok provides 24/7 omnidirectional surveillance with 360-degree coverage across a broad frequency spectrum. Operating on passive principles, the device emits no signals, rendering it invisible to enemy electronic warfare reconnaissance assets and enhancing operator security.
The system’s compact size and portability enable deployment in urban environments, open terrain, and forested areas. Operators can mount the unit on a standard passenger vehicle rooftop and power it through a cigarette lighter socket. Any Android-enabled portable device handles control and data visualization.
Field testing in active combat zones has validated the system’s reliability and effectiveness under operational conditions. Rostec is now preparing for serial production and scaling the technology across multiple applications.
Ogonyok integrates into comprehensive counter-UAV systems, complementing passive radar and electronic warfare jamming solutions. This multi-layered approach enhances detection and neutralization capabilities against low-observable drones.
The shift toward passive radio reconnaissance and countermeasures provides covert, long-term protection against aerial threats without compromising equipment or personnel positions, Rostec noted.
