The GPS Aided Geo Augmented Navigation or GPS and Geo Augmented Navigation system (GAGAN) is a planned implementation of a Satellite Based Augmentation System (SBAS) by the Indian government. (Gagan is the transliteration of a Hindi word that means sky.) It is a system to improve the accuracy of a GNSS receiver by providing reference signals. Being developed jointly by the Airports Authority of India (AAI) and the Indian Space Research Organization (ISRO), the project is being integrated with the geostationary satellite GSAT-4 and has a goal of being operational in 2008.^[1][2] Augmentation of a Global Navigation Satellite System (GNSS) is a method of improving system attributes such as accuracy, reliability, and availability through the integrated of external information into the calculation process. ... ...
