The Airports Authority of India (AAI) completed a trial at Kishangarh airport in Rajasthan, using the latest technology produced by a native satellite-based augmentation system (SBAS) called GAGAN (GPS Aided GEO Augmented Navigation).

India is the first country in the Asia-Pacific to do so.

The airport tested GAGAN (GPS Aided GEO Augmented Navigation) based Localizer Performance with Vertical Guidance LPV approach techniques.

The tests were carried out with the help of the DGCA team. According to media sources, this innovative technology provides a significant operational boost in severe weather and limited visibility.

GAGAN is a space-based augmented navigation system jointly developed by AAI and ISRO in India.

It is the first system of its kind designed for India and its tropical neighbors. It helps in natural disasters such as floods and earthquakes by delivering messages to those affected.

According to the Department of Civil Aviation, the IndiGo aircraft used GAGAN Service to fly an aircraft using an Instrument Approach Procedure (IAP) with an LPV minimum of 250 feet.

In inclement weather and visibility, the choice to lower the height to 250 feet gives a significant operational advantage.

The government's announcement revealed that the new technology would help planes land at rural airports.

As a result, any airport that previously required greater visibility minimums could accept aircraft to benefit distant airports that lack equipment for accurate approach capability.

It is a Satellite-Based Augmentation System (SBAS) developed in conjunction with the Indian Airport Authority (AAI).

The main goals of GAGAN are to provide accurate and reliable satellite navigation systems for civil aviation applications along with improving air traffic management in Indian airspace.

The system will be compatible with other global SBAS systems and would allow smooth navigation across regional borders. GSAT-8 and GSAT-10 provide access to the GAGAN Signal-In-Space (SIS).
