India: According to the recent news, a senior official of Airports Authority of India (AAI) mentioned delay in the India’s GPS-Aided GEO Augmented Navigation (Gagan) project. It is said to be pushed back to the end of the year. However, according to an earlier statement by the Director General of Civil Aviation (DGCA), it was likely to be launched in the summer of 2013.
As in news, Raytheon is building the ground stations for the Gagan System, which will provide satellite-based navigation for civil aviation over Indian airspace and adjoining areas in South and East Asia. The Indian Space Research Organization (ISRO) and AAI are providing the space segment, additional ground equipment, as well as participating in the integration and operating the system.
Gagan is said to leverage differential GPS technology to augment the standard GPS service, adding integrity to the GPS signal and improving its accuracy. It is said to be emerging as the only satellite-based augmentation system that has an enhanced algorithm specifically for the equatorial region of the world.
According to analysis from Boeing and KPMG, over the next 20 years nearly half of the world’s air traffic is expected to fly to or from the Asia Pacific region–growth factor of 6.4 percent with 12,000 additional aircraft needed to join the existing fleet of 4,700. As in news, Gagan will improve safety, reduce congestion and enhance communications to meet India’s growing air traffic management needs.
