- Improves GPS accuracy for aviation and navigation.
- Expected to support land-based RTK applications in future.
Detailed Explanation
The GAGAN system, which stands for GPS Aided GEO Augmented Navigation, is a significant development in enhancing GPS accuracy. It is a collaborative project developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI). This system aims to improve the accuracy of GPS signals, particularly for aviation and navigation purposes. Currently, GAGAN is operational and is widely utilized in the aviation sector to provide precise positional information, which is essential for flight operations. Looking ahead, GAGAN has the potential to support land-based Real-Time Kinematic (RTK) applications, which require highly accurate positioning for various surveying needs.
Examples & Analogies
Imagine you are trying to find your way using a map on your phone. Sometimes, your location might not be accurately represented on the map if you're in a dense building area or near tall structures. GAGAN acts like a 'smart compass' that enhances the accuracy of your phone's GPS, allowing you to navigate more precisely, similar to having a detailed map that is updated in real-time, making it easier for pilots and navigators to determine their exact location.
