Airports Authority of India has offered GPS-aided Geo Augmented Navigation (GAGAN) to SAARC and Southeast Asian countries.

A two-day workshop was organised by AAI on March 15 and 16 for civil aviation representatives from SAARC and Southeast Asian nations to demonstrate the performance and benefits of GAGAN.

AAI in association with Indian Space Research Organisation (ISRO) had developed and deployed the Satellite Based Augmentation System (SBAS) which augments GNSS (Global Navigation Satellite Systems) signals through the use of additional satellite-broadcasting techniques. India is amongst only four nations in the world to develop and deploy this ingenious technology that removes the signal errors from GNSS and provides highly precise navigation signals to the users. Other countries and regions that use such a system are the United States of America, Japan and the European Union.

Implementing an SBAS system is a long-term investment for India, which will go a long way in bringing operational efficiencies to the civil aviation environment as well as non-aviation sectors like developing Smart Cities, intelligent transportation, town-planning, maritime, highways, railways, surveying, security, telecom, geodesy and personal usage that require precise navigation, positioning and timing signals.
