INSAT-3DS, also known as Indian National Satellite System-3 Data Services, is an advanced meteorological satellite developed and operated by the Indian Space Research Organisation (ISRO). Here’s a summary of the satellite:


  • Enhance weather forecasting and disaster warning capabilities in India.
  • Monitor land and ocean surfaces for various applications, including agriculture, water resources management, and environmental monitoring.
  • Augment the existing meteorological services provided by INSAT-3D and INSAT-3DR satellites.

Key Features:

  • Imaging payloads:
    • Advanced Very High Resolution Radiometer (AVHRR) for visible, infrared, and water vapor imaging.
    • Infrasound Sounder (INSAT-3D Sounder) for atmospheric temperature and humidity profiling.
  • Search and Rescue Service-Aided by Distress and Relay (SASAR) payload for distress alert detection and relay.
  • Data Relay Transponder (DRT) for relaying data from other satellites and data collection platforms.


  • Successfully launched on February 17, 2024, onboard the GSLV-F14 rocket from Satish Dhawan Space Centre, Sriharikota.

Current Status:

  • Undergoing in-orbit testing and is expected to begin operational service soon.


  • Improved accuracy and timeliness of weather forecasts.
  • More effective disaster preparedness and response.
  • Enhanced monitoring of environmental changes.
  • Support for various applications in agriculture, water resources management, and other sectors.
