Indian National Centre for Ocean Information Service (INCOIS)

In Kerala, the Indian National Centre for Ocean Information Services (INCOIS) is planning to provide real-time information on the market price of fishes and allied news through the GPS-enabled GEO Augmented Navigation (GAGAN).

GAGAN was developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI) at a cost of Rs. 774 crore, over 15 years.

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.

India is the fourth country to offer space-based satellite navigation services to the aviation sector.

The system bridges the gap in the coverage areas of the European Union’s European Geostationary Navigation Overlay Service (EGNOS) and Japan’s Multi-functional Satellite Augmentation System (MSAS).

The system would be available for the member states of the South Asian Association for Regional Cooperation (SAARC).

It is intended to serve as a low-cost substitute for instrument landing system (ILS) and provide very accurate route guidance for the aircraft to save time and fuel.

The guided approach landing with the help of GAGAN would immediately benefit nearly 50 airports in India.

Indian National Center for Ocean Information Services (INCOIS) is an autonomous organization of the Government of India, under the Ministry of Earth Sciences.

INCOIS is mandated to provide the best possible ocean information and advisory services to society, industry, government agencies and the scientific community through sustained ocean observations and constant improvements through systematic and focused research.
