GAGAN stands for GPS-Aided Geo Augmented Navigation (GAGAN) is a satellite based navigation system that will serve as a low cost substitute to GPS service over the India, Bay of Bengal, South-east Asia and Middle East along with expansion up to Africa. The system has been jointly developed by ISRO and AAI. It is primarily being used in aviation sector for precise position information Services.
With this, India becomes the third country in the world, after USA and European Union, to offer Global Navigational Satellite System (GNSS) based precision approach services to civil aviation sector.
It will make airline operations more efficient by increasing fuel savings, direct routes, ease of search and rescue operations, reduced workload of flight crew and Air Traffic Controllers and cost savings due to withdrawal of ground aids.
