The satellite enabled data and services are being used for the benefit of various sectors of the country. These include Television broadcasting, Direct-to-Home, ATM, Mobile communication, tele-education, tele-medicine and advisories on weather, pest infestation, agro-meteorology and potential fishing zones.

ISRO has plans to launch more number of satellites to further enhance operational applications and cater the needs of emerging applications and user ministerial requirements in the country.
Many of the applications have been effectively adopted by stakeholder departments for operational use. A few of such applications include: Potential Fishing Zone Forecast & Ocean State Forecast by Indian National Centre for Ocean Information Services, (MoES), Crop Acreage and Production Forecasting & National Agricultural Drought Assessment and Monitoring System.
