Difference Between GAGAN and GPS
Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information anywhere on Earth. GPS is widely used for navigation, surveying, and tracking applications. GAGAN (GPS Aided Geo Augmented Navigation) is a satellite-based augmentation system developed by the Indian Space Research Organization (ISRO) to improve the accuracy and reliability of GPS signals in India and neighboring regions.
