    GAGAN is the acronym for GPS Aided GEO Augmented Navigation. The GAGAN uses a system of ground stations to provide necessary augmentations to the GPS standard positioning service(SPS) navigation signal. A network of precisely surveyed ground reference stations (INdian REference Stations : INRES) is strategically positioned across the country to collect GPS satellite data. Using this information, the master control centre (INdian Master Control Centre : INMCC) generates messages to correct any signal errors.


    The Bay of Bengal Arabian Sea Safety Monitoring Agency (BOBASMA) was established by Airports Authority of India to provide monitoring services for international Oceanic airspace and to conduct safety assessments to support implementation of Reduce Horizontal Separation.
