Raytheon was awarded an $82 million contract to modernize the air navigation system in India. Under terms of the contract, awarded by the Indian Space Research Organization (ISRO), Raytheon will build the ground stations for the GPS-Aided Geosynchronous Augmented Navigation System, and ISRO will provide the space segment and additional ground equipment. GAGAN will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in South and East Asia. "Our GAGAN solution addresses the four essential elements of safe air navigation: accuracy, integrity, availability and continuity," said Fritz Treyz, Raytheon Network Centric Systems director of Business Development who led the Raytheon team pursuing the GAGAN initiative. Raytheon expects to have the GAGAN system fully functional by 2013.
