ISRO’s Gagan: Third eye for pilots

Bangalore: The ISRO developed Satellite- Based Regional GPS Augmentation System (Gagan), which will be used for navigation and air traffic management by the Airports Authority of India (AAI) is expected to make India’s air traffic safer and better managed.
Gagan is in the final stage of implementation, according to sources in the Indian Space Research Organisation.
“The technology demonstration system (TDS) has been tested and completed, and the final stage of implementation is expected to take place by the end of the year or next,” sources told Express. The Rs 774-crore project conceived in 2001 is expected to help AAI manage its airspace better, save fuel and improve efficiency for airlines. The satellite based navigation system will make India the fourth nation to possess such a system and is expected to allow higher air traffic to operate within the country’s airspace.
The ground based terrestrial navigation system that the AAI presently uses to manage traffic in the Indian airspace has range problems and other limitations. Gagan was endorsed to overcome the limitations of the ground-based system.
Gagan will help aircraft navigate on a straight path instead of in a zigzag path over land based stations.
Gagan will also cover oceanic areas inaccessible to terrestrial systems.
