Planning of the GPS jamming was initiated months in advance. According to Johnson, the GPS jammers had a vertical reach in upwards of 30,000 feet, so the first step was contacting the FAA, which provided a list of “green” times when commercial air traffic was at its lowest. This led to the testing being performed between 1 and 6 a.m.
NV won a $36.5 million firm-fixed-price, cost-plus-fixed-fee, cost-only contract for production of Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.1 dismounted systems to meet the requirements of US troops in Iraq and Afghanistan. Dismounted JCREW systems are electronic jammers designed to prevent the initiation of radio-controlled improvised explosive devices (RCIED).
The Dismounted Counter Radio-Controlled Improvised Explosive Device Electronic Warfare system is part of the wider Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) series of IED jammers.
