The Indian Space Research Organization has awarded an $82 million contract to Raytheon
to modernize the Indian air navigation system. 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. Raytheon is the only company that has delivered satellite-based augmentation systems that have been certified for safety-of-flight operations. The company developed the Federal Aviation Administration's Wide Area Augmentation System and was engaged in the Japan Civil Aviation Bureau's Multi-Function Transport Satellite Augmentation System.
