GAGAN (GPS Aided Geo Augmented Navigation)

GAGAN (GPS Aided Geo Augmented Navigation) is an advanced satellite-based navigation system developed in India. It enhances the accuracy and reliability of GPS by using ground stations to monitor GPS signals and then correcting any errors. This system helps provide precise positioning information, which is crucial for aviation, mapping, and various transport services. GAGAN improves navigation services over India and surrounding regions, allowing for safer and more efficient travel by enabling things like better approach paths for aircraft and improved navigation for other vehicles and services.
