Grintek Ewation’s GMJ9000 man-portable Radio Controlled Improvised Explosive Devices (RCIED) jammer is now in production for an undisclosed customer. The jammer is designed to prevent the detonation of RCIED that have become a serious threat in many peacekeeping and low intensity conflict scenarios.
The South African company says the GMJ9000 series utilises the latest radio frequency and digital signal synthesis technology “to achieve outstanding suppression of remote activation signals”. Broadband antennas, highly efficient electronic circuitry and sophisticated countermeasure algorithms combine in a cutting edge solution to short-range RCIED protection requirements, they added in a media statement released at last week’s Africa Aerospace and Defence exhibition.
Grintek Ewation CE Carel van der Merwe says “the GMJ9000 series of RCIED jammers will contribute towards safekeeping of personnel and equipment deployed in low intensity conflict or peacekeeping operations, efficiently preventing the detonation of radio controlled explosive devices while allowing the soldier to focus on his primary mission.”
The unit defends against radio controlled explosive devices by utilising a wideband radio frequency transmitter to create radio interference that prevents the device from triggering. This interference blocks radio signals from cell phones, walkie talkies and satellite phones as well as all popular communication equipment used as triggering devices for remote controlled bombs. Company literature adds the family operates in the 20 MHz to 500 MHz band (GMJ9000V) as well as in the
500 MHz to 2.5GHz (GMJ9000U). It is able to jam multiple threats simultaneously and blocked bands are definable for preventing disruption of own force communications. Grintek Ewation adds that counters for new threats easily added by trained personnel.
A mobile RCIED jammer which may be mounted into vehicles and used in convoy protection is also available.
