The "Blagokrai" company began the development of a portable radio-electronic means of combating unmanned aerial vehicles TM KOBZAR "Three Crows", which is designed to protect positions, small objects, civil and military evacuation vehicles, as well as troops and personnel from FPV UAVs. The product has a modular system and works on different frequency bands by the method of generating high-density interference and suppressing them by forming radio frequency noise. This product allows you to save the lives of both military personnel and civilians (non-combatants) from damage by aerial drones as much as possible, and provides protection and integrity to civilian infrastructure objects in the territory adjacent to the combat zone and potentially attacked by UAVs of the russian federation.
