BANGALORE, India, Nov. 16, 2004  /PRNewswire-FirstCall/ -- Raytheon Company
(NYSE: RTN) has signed a contract with the Indian Space Research Organization
(ISRO) Satellite Center for the ground-based elements of the GPS (Global
Positioning System) and GEO (Geostationary Earth Orbit) Augmented Navigation
(GAGAN) Technology Demonstration System (TDS).  The contract, terms of which
were not disclosed, was signed recently in Bangalore.

    GAGAN-TDS, a cooperative effort between Raytheon and ISRO, will usher in a
new era in civil navigation through use of the space-based augmentation
system.  When completed, GAGAN will augment the standard positioning signals
from the GPS satellites with an additional signal to improve the accuracy,
integrity, continuity, and availability of the aircraft receiver.  The GAGAN
project is part of a world-wide movement toward space-based navigation, which
has been endorsed by the International Civil Aviation Organization.  It will
increase safety and efficiency by allowing precision approaches to all
airports and direct routing between destinations.

    The Airports Authority of India is collaborating with ISRO on the project
and will be the agency to place the commissioned system into operation.  Other
modes of transportation, such as rail, maritime, and road traffic, will also
be able to use the signal for a variety of applications.

    "Signing the GAGAN contract is a great development in U.S.-India space and
air traffic management cooperation," said Sue Baumgarten, president, Raytheon
International.  "It is another example of the deepening relationship between
our two countries, as well as the expanding opportunities for Raytheon in
India.  This is an important relationship for Raytheon, and we are committed
to earning the confidence of our Indian customers."

    Raytheon will develop the hardware and software for the ground-based
elements of GAGAN, which will consist of eight Indian reference stations, an
Indian master control center, and an Indian land uplink station.  All the
subsystems will be integrated through a digital communication system that ISRO
will supply, and the correction messages will be broadcast from a
geosynchronous satellite that ISRO will launch.

    "This is a challenging project, both because of its technical complexity
and the high degree of collaboration required for success," said Bob Eckel,
vice president for Raytheon Air Traffic Management Systems.  "We are confident
that our excellent partnership with ISRO and AAI will bring success and set
new standards for efficient and safe air travel."

    Raytheon will base its design on WAAS (the Wide Area Augmentation System),
which was commissioned by the U.S. Federal Aviation Administration in July
2003.

    Raytheon Company, with 2003 sales of $18.1 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 78,000 people worldwide.

    Note to Editors:  The work on this contract will be performed in
Fullerton, Calif., and Bangalore, India.
