Russian Technology Group Launches Fiber-Optic-Based Invisible Drone Detection and Positioning Device
Author: Dmitry Zubarev
Russian engineers have launched a new three-coordinate passive positioning device that can detect drones and other low-observability targets tens of kilometers away without being detected by radio reconnaissance.
The "Vektor" research institute (NII "Vektor"), owned by the "Rosel" holding company under the Russian State Technology Corporation (Rostec), has developed a compact passive positioning device that can detect low-observability targets, including drones, through fiber-optic lines. This was reported by RIA Novosti.
This innovative device - the 3D PKL (Three-Dimensional Passive Coherent Locator) - differs from traditional radar in that it does not emit its own signals, thus avoiding detection by radio reconnaissance.
The device captures reflected signals from external radio and television transmitters, then calculates the precise coordinates of the target in terms of distance, azimuth, and altitude by analyzing the phase and amplitude of the signals. The Russian Technology Group stated that this positioning device can detect light aircraft tens of kilometers away and effectively identify various stealthy targets, including drones on fiber-optic lines.
Natalia Kotlyar, Deputy Director for Business Development at the "Vektor" research institute, said that the device maintains its effectiveness in complex radio technology environments, and even in concrete structures, it can distinguish multiple reflected signals. She said, "Unlike optical and infrared systems, the 3D PKL works effectively under any weather conditions and at any time. The device does not produce its own radiation, so it cannot be detected by radio reconnaissance methods. In this way, its use does not reveal the working location."
The Russian Technology Group news office added that this new product does not require authorized frequency bands, can be powered by weak power sources, is easy to integrate into existing infrastructure, and helps reduce the operating costs of the system.
As previously reported by "Glas," the "Rosel" company warned that drone attacks will increase in the coming years. The holding company has developed a new device that enables navigation of aircraft and drones without satellite communication, which has successfully passed flight tests and is about to enter mass production. The Russian Technology Group has also launched the production of a drone "friend-or-foe identification" system.
