Bangalore airport ready for satellite navigation


Bangalore airport ready for satellite navigation
Passengers from Bangalore airport will get to depart and arrive on time on almost every flight as a satellite-based navigation system, as against a ground-based system, will ensure there are no delays in landing, long queues of aircraft to land or take off, delays in take-off and extended hovering.

Bangalore airport is ready for the system, GPS Aided Geo Augmented Navigation or GAGAN, which is set to begin operations December-end. The system is being implemented both by Airports Authority of India (AAI) and Isro. AAI and Isro both confirmed the December target for GAGAN.

Isro, which is implementing this satellite-based navigation, has said tests are currently underway by AAI to check information flow between Air Traffic Control (ATC) and the flights to ensure that the satellite signals coming to an aircraft are being received correctly. The airport too will receive signals from the satellite and so it will be a three-way communication – between satellite, airport and aircraft.

Isro spokesperson Deviprasad Karnik told Deccan Herald that the new system will help aircraft land and take off precisely, get information accurately about their height and altitude and height from the ground especially when landing. These small aids would reduce the time to land and take off and aircraft save fuel and time. They can fly precisely as per schedule. The typical experience of passengers, for instance, on the Bangalore-Delhi flight has been the long queue of aircraft to land at Delhi airport.

The information about the aircraft waiting, after this new system comes in, will be relayed to an incoming aircraft in advance via satellite signals and the aircraft concerned can then adjust its speed and approach to Delhi. Passengers after long haul flights are impatient to alight and waiting time to alight is high. The new system will ensure the aircraft lands early and beat the rush at the airport. It will also help in reducing the hovering time when waiting to land. If the speed of the aircraft is managed to reach an airport when the queue has shortened, it will hover less and save time.
