About INSAT-3DR

• INSAT-3DR (Indian National Satellite-3DR) is an advanced meteorological satellite developed by ISRO. 
• Objectives: Improve weather forecasting, cyclone tracking, disaster warning, and environmental monitoring over India and the surrounding region. 
• It was launched on 8 September 2016 aboard the GSLV-F05 launch vehicle. 
• It is configured with an Imaging System, and an Atmospheric Sounder. 
• Like its predecessor INSAT-3D, INSAT-3DR carries a Data Relay Transponder as well as a Search and Rescue Transponder. 
• Thus, INSAT-3DR will provide service continuity to earlier meteorological missions of ISRO and further augment the capability to provide various meteorological as well as search and rescue services. 
• It provides half-hourly multispectral images over the Indian region from a geostationary position. 
• The significant improvements incorporated in INSAT-3DR are:
  • Imaging in the middle infrared band to provide nighttime pictures of low clouds and fog.
  • Imaging in two thermal infrared bands for estimation of Sea Surface Temperature (SST) with better accuracy.
  • Higher spatial resolution in the Visible and Thermal Infrared bands.
