India will launch the new GPS Aided Geo Augmented Navigation (GAGAN) satellite to aid air traffic navigation in the country and neighbouring regions.
The satellite-based navigation system has been developed by Airports Authority of India and Indian Space Research Organisation.
GAGAN will provide a civil aeronautical navigation signal consistent with International Civil Aviation Organization standards and practices, established by the Global Navigation Satellite System Panel.
The system is expected to improve efficiency in the civil aviation sector, as well as increase fuel savings, facilitate precision approach at all runways, enhance air-to-air surveillance and reduce the workload of air traffic controllers.
The project will involve the establishment of 15 reference stations, three navigation land uplink stations, three mission control centres and three geo-stationary navigation payloads in C and L bands with all associated software and communication links.
GAGAN will be interoperable with the wide-area augmentation system of the US, the geostationary navigation overlay service of the EU and the multi-functional satellite augmentation system of Japan.
