Satcom Application

Satellite Communication (Satcom) technology offers the unique capability of at the same time reaching out to very large numbers spread over large distances even in the most remote corners of the country. The hallmark of Indian Space Programme has been the application oriented efforts and the benefits that have accrued to the country.

In the past two and a half decades Indian National Satellite (INSAT) system have revolutionized the country’s telecommunications, TV broadcasting, DTH services, business communications, rural area connectivity, Tele-education, Tele-medicine, Village Resource Centers, Search and Rescue operations and Emergency Communications.

INSAT system is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. Established in 1983, INSAT system is one of the largest domestic communication satellite systems in the Asia Pacific Region with eleven satellites in operation. These satellites carry more than 200 transponders in the C, Extended C and Ku-bands, besides meteorological instruments.
INSAT is used for a variety of societal applications in the area of Tele-education, Tele-medicine and support to the Disaster Management System (DMS).

Village Resource Centre (VRC), a single window agency providing the services offered by INSAT and IRS satellites to provide information on natural resources, land and water resources management, Tele-medicine, Tele-education, adult education, vocational training, health-care and family welfare programmes, has been established. Meteorological data from INSAT is used for weather forecasting and specially designed disaster warning receivers have been installed in vulnerable coastal areas for direct transmission of warnings against impending disaster like cyclones.
