Raytheon Company 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
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.
