Raytheon Next-Generation GPS Receiver Tracks Live Satellite M-code for the First Time

EL SEGUNDO, Calif., Nov. 6, 2006 /PRNewswire/ -- Raytheon Company (NYSE: RTN) has achieved a key milestone on the Modernized User Equipment program by successfully acquiring and tracking for the first time a new M-code military signal transmitted by the latest-generation global positioning system satellite.

Although the first modernized satellite, GPS Block IIR-14(M), has been operating with legacy signals since December 2005, it only recently began test broadcast of the new M-code. The code provides enhanced accuracy, encryption and anti-jamming capability for authorized users.

"This initial success demonstrating the ability of our next-generation receivers to track the new modernized GPS signal is a key step forward for our modern user equipment program," said Dr. Ralph Garcia, director of GPS and navigation systems for the company's Space and Airborne Systems business. "It also marks a significant milestone for the government-industry GPS team by demonstrating synchronized user equipment, satellite, and control system interoperablility, which is critical for our customer's operations in the future."

A Raytheon prototype receiver, produced under the research and development agreement of the program, was used to track the new signal from the GPS Block IIR-14(M) satellite.

"The successful receiver operation with a live M-code satellite inspires confidence that our design is sound and validates our simulation environment," said Phil Kelton, who manages the modern user equipment program. "These will be critical tools as we progress toward a production-ready product. The next phase of the program will benefit from breakthroughs in microelectronics technology, coupled with advanced security solutions to permit higher performance and greater integrity at less cost than today's systems." Raytheon's teammates on the program are General Dynamics and Trimble Navigation Limited.

The Global Positioning Systems Wing of the U.S. Air Force Space and Missile Systems Center awarded Raytheon a $38 million contract in June to develop a receiver card for the program. The team is developing next-generation circuit card technology, which will enable military users to connect with new navigation signals from enhanced global positioning satellites while retaining compatibility with the current constellation and legacy signals.

Raytheon Space and Airborne Systems is the leading provider of sensor systems giving military forces the most accurate and timely information available for the network-centric battlefield. With 2005 revenues of $4.2 billion and 13,000 employees, SAS is headquartered in El Segundo, Calif. Additional facilities are in Goleta, Calif.; Forest, Miss.; Dallas, McKinney and Plano, Texas; and several international locations.

Raytheon Company, with 2005 sales of $21.9 billion, is an industry leader in defense and government electronics, space, information technology, technical services, and business and special mission aircraft. With headquarters in Waltham, Mass., Raytheon employs 80,000 people worldwide.
