Context: Scientists tracking extreme climate affecting the country will soon be facilitated with improved satellite data and high-resolution images of the Earth obtained from the soon-to-be-launched INSAT-3DS.


  • About: INSAT-3DS Satellite represents a follow-on mission of the Third Generation Meteorological Satellite from Geostationary Orbit.
  • Orbit Adjustment: Subsequent orbit-raising maneuvers will ensure that the satellite is positioned in a Geo-stationary Orbit, optimizing its functionality.
  • Funding and Support: The GSLV-F14/INSAT-3DS mission is fully funded by the Ministry of Earth Sciences (MoES), highlighting government support for advanced meteorological endeavors.
  • Enhanced Capabilities: The mission is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning.
  • Augmentation of Services: The INSAT-3DS satellite will augment the Meteorological services alongside the presently operational INSAT-3D and INSAT-3DR satellites, bolstering India's capabilities in weather monitoring.

The primary objectives of the mission are:

  • To monitor Earth’s surface, carry out Oceanic observations and its environment in various spectral channels of meteorological importance.
  • To provide the vertical profile of various meteorological parameters of the Atmosphere.
  • To provide the Data Collection and Data Dissemination capabilities from the Data Collection Platforms (DCPs).
  • To provide Satellite Aided Search and Rescue services.
