Airports Authority of India (AAI) is pleased to announce today thatlight trial using GAGAN (GPS Aided GEO Augmented
Navigation) based LPV Approach Procedures was successfully conducted at Kishangarh Airport, Rajasthan. The successful trail is a great achievement and major milestone in field of Air Navigation Services (ANS) in the history of Indian Civil Aviation Sector. India is the first country in Asia Pacific Region to achieve such a landmark. LPV (Localizer Performance with Vertical Guidance) permits aircraft guided
approaches that are operationally nearly equivalent to Cat-I ILS, without the need for ground-based navigational infrastructure. The service relies on the availability of GPS and GAGAN Geo Stationary Satellites (GSAT-8, GSAT-10 and GSAT- 15), launched by ISRO. GAGAN is an Indian Satellite Based Augmentation System (SBAS) jointly developed by AAI and ISRO. It is the first such system developed for India and neighboring countries in the equatorial region. GAGAN System was certified by DGCA in 2015 for Approach with Vertical Guidance (APV 1) and en-route (RNP 0.1) operations. There are only four Space-Based augmentation systems available
in the world namely India (GAGAN), US(WAAS) Europe (EGNOS) and Japan (MSAS). GAGAN is the first such system developed for India and neighboring countries in the equatorial region.
