L-3 Communications/Interstate Electronics Corporation to Demonstrate GPS Anti-Jamming Solutions at JAMFEST 2005

Both STAP and Deeply Integrated GPS/Inertial Systems will be demonstrated

ANAHEIM, CA - February 22, 2005 Interstate Electronics Corporation (IEC), a wholly owned subsidiary of L-3 Communications Corporation (NYSE:LLL), announces participation in the upcoming JAMFEST 2005 to be held at White Sands Proving Grounds, Las Cruces, New Mexico.

IEC will be demonstrating the effectiveness of its GPS anti-jam technology in the presence of live open-air jammers, including demonstrations of IEC's proprietary FaSTAPTM anti-jamming technology and deeply integrated GPS/inertial navigation systems.

IEC's FaSTAPTM uses multiple antenna elements and IEC's unique Fast Space-Time Adaptive Processing algorithms to provide immunity against multiple jammers, either in appliqué form or integrated with a dedicated GPS receiver. IEC has integrated FaSTAPTM with GPS in a single unit the size of current generation GPS receivers without this capability. Alternatively, FaSTAPTM anti-jamming appliqués allow the incorporation of this technology with no changes to the GPS receivers in existing navigation systems.

Deeply integrated GPS navigation systems can deliver a 15 to 20 dB improvement in tracking performance through jamming over a conventional GPS navigation system mechanizing standard code and carrier tracking loops. IEC's implementation of deeply integrated GPS/inertial navigation has reduced the size, weight and power needed to implement this technology to levels capable of incorporation into today's guided weapons. Deeply integrated systems can also be incorporated to upgrade the performance reliability of existing vehicles or weapons in jammed environments.

"Our engineers have incorporated very sophisticated technologies to produce the software and hardware solutions that can be cost-effectively added to the customers' guidance systems', notes Robert Huffman, President of IEC. "The Star Wars-like battlefields of the future will present performance challenges to any vehicle or handheld device when combatants attempt to penetrate an area protected by sophisticated jamming systems. We are confident our GPS navigation systems will deliver superior performance."

At Jamfest, participants will be able to walk, drive or fly through GPS jamming environments to test their GPS receivers or train their personnel to recognize the effects of GPS jamming on their missions. Through GPS JPO and White Sands Missile Range sponsorship, the 746th Test Squadron will set up and characterize the jamming environment and provide a "quick-look" report stating when jammers were activated and describing the active interference signals.
