Civil Aviation Minister Ashok Gajapathi Raju has launched the GPS-Aided Geo Augmented Navigation (GAGAN) system. This indigenously developed system will make airline operations more efficient and reduce costs. GAGAN will offer seamless navigation to the aviation industry. GAGAN will provide augmentation service for GPS over the country, Bay of Bengal, South East Asia and Middle East expanding up to Africa.
GAGAN is a satellite based navigation system that will serve as a low cost substitute for Instrument Landing System (ILS)
It provides autonomous, high precision geo-spatial location information of the user in terms of latitude, longitude and height along with velocity and time.
GAGAN was jointly developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI), at an investment of Rs 774 crore.
The benefits of GAGAN include improved efficiency, direct routes, increased fuel savings, approach with vertical guidance at runways, significant cost savings due to withdrawal of ground aids and reduced workload of flight crew and Air Traffic Controllers.
