MARLBORO, Mass., (Sept. 6, 2001) - Raytheon Company and the U.S. Air Force have successfully completed the initial phase of flight testing of a system that provides accurate and reliable landing guidance for both rotary and fixed wing aircraft during low visibility (Category I and II) approaches.

The system, known as the Joint Precision Approach and Landing System, or JPALS, works with the Global Positioning System (GPS) satellite constellation. JPALS is a joint Department of Defense (DoD) development to provide an all weather, all mission, all user capability for the U.S. Air Force, Navy, Army and Marine Corps.

The flight testing, which took place at Holloman AFB, N.M., employed a Raytheon- developed JPALS demonstration system based on local area differential GPS technology. During the testing, several successful Category I landings were achieved using a demonstration ground station and an Air Force C-12J outfitted with the JPALS airborne demonstration system and cockpit display. Category I landings were achieved using both a standard military GPS receiver and a Raytheon-developed advanced technology anti-jam GPS receiver.

JPALS ground equipment configurations support fixed base, tactical and special mission applications. The airborne JPALS function can be hosted in all avionics configurations including the multi-mode receiver, embedded GPS/INS and the military airborne GPS receiver.

"During this phase of flight testing the JPALS demonstration system achieved accuracy levels that exceed the Category II requirements," said Eric Lekberg, the Air Force program manager for JPALS. "This successful milestone is the result of open communication and exceptional teamwork between the Air Force and Raytheon. The solid engineering process applied during system design, development, and laboratory testing played a major role in the what the JPALS team was able to achieve at Holloman."

Raytheon is the world leader in designing and building satellite based navigation and landing solutions for civil and military applications. In addition to developing JPALS for the DoD, Raytheon is also developing both the Local Area Augmentation System (LAAS) and the Wide Area Augmentation System (WAAS) for the Federal Aviation Administration. JPALS and LAAS will provide an interoperable landing capability for military and civil applications.

With headquarters in Lexington, Mass., Raytheon Company (NYSE: RTN) is a global technology leader in defense, government and commercial electronics, and business and special mission aircraft.
