Civil aviation minister Ashok Gajapathi Raju on 13 July 2015 launched the new navigation system, which would make airline operations more efficient and cut down costs as it reduces separation between aircrafts, increase air safety and fuel efficiency. What is the name of the navigation system?: GPS-Aided Geo Augmented Navigation system - GAGAN
Explanation: GAGAN is the first SBAS (Satellite Based Augmentation System) in the world certified for approach with vertical guidance operating in the equatorial ionospheric region and the third SBAS to have achieved this feat, after WAAS (Wide Area Augmentation System) of the USA and EGNOS (European Geostationary Navigation Overlay Service) of Europe. Aided Geo Augmented Navigation system - GAGAN is jointly developed by Indian Space Research Organization (Isro) and Airports Authority of India, at an investment of Rs 774 crore, the system will offer seamless navigation to the aviation industry. The system will provide augmentation service for GPS over the country, Bay of Bengal, south east Asia and Middle East expanding up to Africa. 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.
