FACTS FOR PRELIMS

Indian National Centre for Ocean Information Services (INCOIS)

It is an autonomous organization of the Government of India, under the Ministry of Earth Sciences, located in Pragathi Nagar, Hyderabad.

It aims to provide ocean information and advisory services to the society, industry, government and scientific community through sustained ocean observations and constant improvements through systematic and focused research.

It provides round-the-clock monitoring and warning services for the coastal population on tsunamis, storm surges, high waves, etc. through the in-house Indian Tsunami Early Warning Centre (ITEWC). The Intergovernmental Oceanographic Commission (IOC) of UNESCO designated ITEWC as a Regional Tsunami Service  Provider (RTSP) to provide tsunami warnings to countries on the Indian Ocean Rim.

GAGAN

It was developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI) .

GAGAN will provide augmentation service for the GPS over the country, the Bay of Bengal, South East Asia and the Middle East and up to Africa.

Some of its benefits are improved efficiency, direct routes, increased fuel savings, approach with vertical guidance at runways, significant cost savings because of the withdrawal of ground aids and reduced workload of the flight crew and air traffic controllers.

Gagan works by augmenting and relaying data from GPS satellites with the help of two augmentation satellites and 15 earth-based reference stations. The system utilises the satellite-based wide area augmentation system (SBAS) technology which has been developed by Raytheon.
