Now planes will land safely even in poor visibility: Commercial jet landing for the first time in India with satellite signal, successful trial of indigenous Gagan system

Now planes will be able to land safely even in poor visibility. Because, for the first time in India, a successful trial has been conducted to land a large commercial jet safely with the help of direct satellite signals without ground radio beam.

On June 27, under the supervision of aviation regulator DGCA, Indigo Airlines’ Airbus A320 aircraft made this historic landing using the indigenous ‘Gagan’ navigation system. Although IndiGo had tested it on smaller ATR aircraft in 2022, this is the first successful trial in the country with a larger commercial jet.

What is Swadeshi Gagan System?

The full name of GAGAN is ‘GPS Aided Geo Augmented Navigation (GAGAN). This is India’s own Satellite-Based Augmentation System (SBAS), jointly developed by the Indian Space Research Organization (ISRO) and the Aviation Authority of India (AAI).

USP: Gagan is not an independent navigation system like India’s ‘NavIC’ or America’s ‘GPS’, which gives direct location. Rather, it corrects imperfections and errors in pre-existing GPS signals, making them more accurate and reliable for aircraft.
