The Directorate General of Civil Aviation (DGCA) conducted India’s first satellite-based landing system (SLS) approach trial on an Airbus A320 at Udaipur Airport using the indigenous GAGAN navigation system.
The trial enabled an IndiGo Airbus A320 to perform a Localiser Performance with Vertical Guidance (LPV) approach for precision landing.
GAGAN (GPS Aided GEO Augmented Navigation) is India’s Satellite Based Augmentation System (SBAS), jointly developed by the Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO).
It improves the accuracy, integrity and reliability of GPS signals by sending correction data through geostationary satellites.
The system reduces dependence on ground-based Instrument Landing Systems (ILS) and improves landing capability at airports with limited infrastructure.
