- 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.
