Airports Authority of India has successfully conducted the Final Acceptance Test of the India’s Satellite Based Augmentation System-GAGAN marking a significant milestone in Indian Aviation and paving way for the scheduled commissioning of the system in Mid-2013.
 
GAGAN (GPS Aided Geo Augmented Navigation) is a prestigious project jointly undertaken by Airports Authority of India and ISRO in accordance with ICAO’s strategic plan to achieve smooth transition to Satellite based Navigation and seamless Air traffic management across the continents.
 
GAGAN Final System Acceptance Test (FSAT) was successfully completed on 16th-17th July 2012. The objective of Final System Acceptance Test was to evaluate the system performance and its critical parameters in the integrated live environment using the satellite signals and ground based systems on integrity, accuracy, continuity and availability for aviation use. The FSAT results have successfully demonstrated that GAGAN Signals meet the ICAO SARPS requirements.
 
Present GAGAN configuration includes 15 Indian Reference Stations (INRES), 2 Indian Master Control centers (INMCC) & 3 Indian Land Uplink Stations (INLUS), 2 GEO satellites (GSAT-8 & GSAT-10). All INRES are integrated with redundant communication links (which include 2 OFC & 2 VSAT links) to transfer data to INMCC.
 
India is only the fourth country in the world, after USA, JAPAN and Europe to take up the challenge of establishing the regional SBAS that will redefine the navigation over India and adjacent regions. The footprint of GAGAN will cover huge area beyond Indian Territory, from Africa to Australia and can support seamless navigation across the Globe.
 

Further, GAGAN is the first system in the world that is being developed to serve the equatorial anomaly region with its unique IONO algorithm designed and developed by scientists and experts from ISRO & AAI in collaboration with Raytheon.
The certification process of the system is under way.

As the footprint of the GAGAN space segment covers large portion of the Asia-Pacific region i.e., the whole of Indian region and neighboring countries such as Srilanka, Pakistan, Afghanistan, Bhutan, Nepal and Bangladesh, all these states can derive benefit of the system to provide SBAS services by appropriately augmenting ground segments.

The GAGAN is designed to provide the additional accuracy, availability, and integrity necessary to enable users to rely on GPS for all phases of flight, from en route through approach for all qualified airports within the GAGAN service volume. GAGAN will also provide the capability for increased accuracy in position reporting, allowing for more uniform and high-quality Air Traffic Management (ATM).

In addition, GAGAN will provide benefits beyond aviation to all modes of transportation, including maritime, highways, railroads and public services such as defense services, security agencies, telecom industry and personal users of position location applications.
