IndiGo Airbus A320 Makes India's First Commercial GAGAN-Guided Landing

An Airbus A320 operated by IndiGo has made aviation history by becoming the first commercial aircraft in India to complete a landing at Udaipur Airport using GAGAN (GPS Aided GEO Augmented Navigation), the country's indigenous satellite-based navigation system. The milestone represents an important step forward in India's efforts to modernize its air navigation infrastructure while improving the safety, precision, and efficiency of commercial flight operations. What Is GAGAN? GAGAN (GPS Aided GEO Augmented Navigation) is India's Satellite-Based Augmentation System (SBAS), jointly developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI). It is designed to enhance the accuracy, integrity, availability, and reliability of satellite navigation signals used by aircraft.
