India’s SBAS to roll out soon

India’s GPS-Aided Geo Augmented Navigation (Gagan) system, jointly developed by Airports Authority of India (AAI), the Indian Space Research Organization and Raytheon, has been awarded certification for in Required Navigation Performance (RNP) 0.1 operations. Achieved with the help of quasi-U.S. government non-profit MITRE Corporation, the certification makes it the world’s fourth SBAS system certified for operational use.

The first test flight using the system will fly an approach in mid-2014 from Ahmedabad in the western state of Gujarat. The aircraft is likely to be an AAI-owned Beechcraft aircraft, according to S.V Satish, general manager (ATM-Gagan), AAI. Raytheon has built 15 ground reference stations for the Gagan System, which will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in South and Southeast Asia.
