What is GAGAN?
GAGAN stands for GPS Aided Augmented Navigation System. It’s the next generation air traffic management system that utilizes satellites to increase GPS accuracy. This increased accuracy yields a number of substantial benefits to air traffic managers, passengers and flight crews.
Raytheon is building the ground stations for the system which will provide satellite navigation for civil aviation over Indian air space and adjoining areas in South and South East Asia.
What are benefits of using GAGAN?
Because of the increased GPS accuracy, airlines will be able to save 20% on fuel costs and passengers will experience shorter flight times. For example, the flight time from Delhi to Mumbai will be reduced by about ten minutes. It will reduce congestion on busy routes as well as enhancing safety.
How is GAGAN able to reduce flight times?
The system improves the accuracy of the GPS signal and this allows traffic managers and pilots to establish shorter, more direct routes to destinations.
How does GAGAN increase safety?
A good example I can give is when a plane is landing. Currently, a pilot will receive coordinates for a landing strip to within about 20 meters of accuracy. Using GAGAN, this same pilot will receive coordinates to within 20 feet of accuracy.
How will GAGAN be able to meet the air traffic management needs of a growing area like India?
By using the new system, India will be able to fly three times as many planes safely within the same air space, providing much needed capacity to accommodate the region’s predicted growth in air traffic.
