About INSAT 3D and INSAT 3DR :

  • INSAT-3DR stands as a technologically advanced weather satellite.
  • Launched into orbit by GSLV-F05.
  • Designed to complement and enhance the services provided by its predecessor, INSAT-3D.
  • Positioned in a Geo Stationary Transfer Orbit (GTO) for effective weather monitoring and data collection.
  • INSAT 3D uses an Red-Green-Blue (RGB) imager to represent solar reflectance and brightness temperature, determining colours.
  • INSAT 3D and INSAT 3DR use radiometers for spectral measurements and atmospheric sounders to study temperature and humidity.
  • INSAT 3D and INSAT 3DR are currently active in geostationary orbits
  • Combining radiometer and sounder data helps understand atmospheric characteristics and track weather events.
