GAGAN Boosts India’s Aviation Self-Reliance
What Happened
India’s indigenous GAGAN (GPS Aided GEO Augmented Navigation) system is gaining recognition as a key pillar of the country’s aerospace and navigation ecosystem. Developed jointly by ISRO and the Airports Authority of India, GAGAN enhances GPS accuracy and improves flight safety. In a major milestone, the DGCA successfully conducted India’s first satellite-based landing approach on a commercial aircraft using GAGAN in June 2026.
Key Takeaways
GAGAN makes India one of the few countries with an operational satellite-based augmentation system, reducing dependence on foreign navigation networks. Beyond aviation, it has applications in defence, maritime transport, railways, disaster management, and mapping.
