Types of products/services offered : counter-drone systems, disturbing/jamming the radio systems (RF, Wi-Fi, GSM, GNSS, telecommunications, CB radio, short-wave radios, satellite phones), jammers, radioelectronics, UAV neutralisation (Unmanned Aerial Vehicles/Drones)
Exemplary products/services : 1. DEFENDER Wideband WB6500 is the advanced, fully-scalable jamming system intended for UCAS electronic warfare, capable of jamming the RF systems in bandwidths of 20 MHz - 6 GHz with total output power of 650W. The applied FPGA-based technology enables fast signal processing both in RX and TX paths. Using the FPGA circuits, in particular in reactive mode, provides a significant advantage over simple (for example VCO) jammers, enabling fast generation of precise jamming signals in relevant frequency bands bandwidths with visible RF signal (higher RF power density). Defender Wideband WB6500 is quickly configurable to cover additional frequencies which may appear at the battlefield. 2. DEFENDER Antidrone 2.0 – a mobile, modular system capable of jamming the RF signals in bandwidths of 350 MHz - 6 GHz with total output power of 550W (RF Modular) 3. DEFENDER Manpack 2.0 – a mobile, modular system capable of jamming the RF signals in bandwidths of 20 MHz - 6 GHz with total output power of 70W (RF)
