▶ Answer & Explanation
Correct answer: D. I and II only
GAGAN is an indigenous satellite-based augmentation system developed by ISRO and Airports Authority of India. Its primary aim is to enhance the accuracy, integrity, and availability of GPS signals for navigation, crucial for improved air traffic management. While its primary application is in aviation, the underlying technology and augmentation principles can potentially extend benefits to other modes of transport like shipping and land-based navigation in the future.
