MARLBORO, Mass., (Feb 21, 2002) - Raytheon Company successfully completed the first in a series of autoland flight tests using its Local Area Augmentation System (LAAS) on January 17, 2002 at the Salt Lake City International Airport.

The aircraft, a Boeing 737-900, equipped with Rockwell-Collins GLU-920 Multi-Mode receivers (MMR) with GLS software, utilized differential GPS corrections and precision approach path data uplinked from a Raytheon RAYNAV-4100 Local Area Augmentation System (LAAS) ground facility at the Salt Lake City Airport. A series of autocoupled (hands-off) approaches, through touchdown and rollout, were conducted using two different runways.

The current flight testing was a continuation of Raytheon's LAAS ground station test program which also included flight tests in August 2001 with a FedEx Express Boeing 727-200 aircraft equipped with a Rockwell-Collins GNLU-930 MMR with GLS software. During those tests, civil-military interoperability of LAAS was demonstrated with Raytheon's civil LAAS ground station in Salt Lake City, and its military joint precision approach and landing system (JPALS) ground station at Holloman AFB in Alamagordo, N.M.

"Raytheon is committed to developing and deploying high integrity, satellite based navigation and landing systems for the flying public,'' said Bob Eckel, Raytheon vice president of Air Traffic Management Systems. "We are working closely with our industry and government partners to bring this technology into operational use. These recent flight tests have moved us one step closer to that goal."

Raytheon is developing LAAS in cooperation with the Federal Aviation Administration (FAA) under a Government-Industry partnership agreement. Later this year, the FAA plans to begin acquisition of LAAS ground stations for installation at airports nationwide. LAAS will initially provide GPS based Category I precision approach capability (200-ft. ceiling, one-half mile visibility). Later versions will provide Cat II/III capability, enabling all-weather automatic landings and surface navigation. LAAS will provide precision approach capability in virtually any environment including mountains, urban areas and offshore platforms. One LAAS will service the entire airport and will allow for tailored approaches to avoid obstacles, noise sensitive areas or congested airspace.

Raytheon is the world leader in designing and building satellite-based navigation and landing solutions for civil and military applications. In addition to developing LAAS, Raytheon is also developing the wide area augmentation system (WAAS) for the FAA and the JPALS for the Department of Defense.

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.

Note to Editors:

CATEGORY I/II/III refer to different levels of low visibility approaches. Aircraft fly on instruments during most of the approach but the pilot must have visual contact with the runway and/or approach lights by the time he reaches the minimum ceiling and/or horizontal visibility listed below. CAT I is the least stringent.
