New Delhi: The government is likely to
approve a grant for the GPS-Aided Geo Augmented
Navigation system on Tuesday, that would provide satellite coverage to air
traffic not only on the entire Indian airspace but across the
Indian Ocean region from South-east Asia to Africa also.
The prestigious project, being developed jointly by the
Airports Authority of India (AAI) and Indian Space Research
Organisation (ISRO), would place India in the fourth position
along with the US, Europe and Japan to have such an advanced
The GPS-Aided Geo Augmented Navigation (GAGAN) system,
being developed at an estimated cost of Rs 774 crore, would
make the sky in this vast area much safer and provide
precision approach to all aircraft either landing at Indian
airports or overflying the airspace, even over the high seas.
"The Union Cabinet is likely to approve the grant-in aid
for the project in its meeting tomorrow," a source said,
although he declined to comment on the quantum of money.
The advanced satellite based navigation system is
scheduled to be completed by June 2013 after completion of
its first phase of technical demonstration in August 2007.
Once operational, the GAGAN project would provide
augmented information for satellite navigation to aircraft
flying over Indian airspace and the routes over the high seas
with high level of accuracy, integrity and continuity at all
phases of flight operations.
The Flight Management System (FMS), based on GAGAN, will
also help the operators to save time and money by managing
climb, descent and engine performance profiles of aircraft.
The FMS will also help in improving airport and airspace
access in all weather conditions, and the ability to meet the
environmental and obstacle clearance constraints.
GAGAN also aims to enhance reliability and reduce delays
by defining more precise terminal area procedures that feature
parallel routes and environmentally optimised airspace
After its final operational phase completion, GAGAN will
be compatible with other Space Based Augmentation Systems like
the Wide Area Augmentation System of the US, the European
Geostationary Navigation Overlay Service and the multi-
functional Satellite Augmentation System of Japan.
Post commissioning of the project, India would become the
fourth country in the world to adopt this system that would
enhance the accuracy and integrity of GPS signals to meet
precision approach requirements in the civil aviation.
