The GEW® GMJ900 specialised jammer system is specifically designed to counter new-generation targets, such as cellular networks, satellite phones, commercial drones, GNSS and Wi-Fi. Utilising the specially designed wave forms and algorithms in combination with high-power, multichannel power amplifiers, excellent target-signal suppression is achieved. The GMJ900 is optimised to jam multiple radio links simultaneously and can be quickly and easily adapted to meet the requirements of the target environment.
