What does GAGAN, a satellite based navigation system, stand for?

Correct option is C

​The correct answer is (c) GPS Aided Geo Augmented Navigation.

• GAGAN is an Indian satellite-based augmentation system (SBAS) developed by the Indian Space Research Organisation (ISRO) in collaboration with the Airports Authority of India (AAI).
• It is designed to improve the accuracy, reliability, and availability of the global positioning system (GPS) signals over India and the surrounding region.
• GAGAN enhances GPS signals for aviation, allowing for better navigation accuracy and safety for aircraft operating in the region.• The system improves the navigation capabilities of GPS by providing satellite signals that are corrected and augmented using ground-based stations.

Information Booster:

• GAGAN is part of India's efforts to improve air traffic management and provide safer and more efficient flight routes.
• The GAGAN system received certification from the Directorate General of Civil Aviation (DGCA) in 2015 for its 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).
