GAGAN ( GPS Aided Geo Augmented Navigation) is the name of Indian version of US's WAAS ( Wide-Area Augmentation system ). Once GAGAN is available, users who have WASS-compatible receivers will be able to get GPS position with accuracy of roughly 1 meter or better. GAGAN is not a replacement for the GPS system but an extension that will make US's GPS more accurate over India and thus can be used for many high-precision aplications. We have collected various links and news articles about GAGAN to give you a comprehensive coverage of India's GPS system.
Below is the timeline and progress of the GAGAN project.
