Indian Space Research Organisation (ISRO) will launch meteorological satellite INSAT-3DS with the GSLV-F14/INSAT-3DS mission set for lift from SDSC-SHAR, Sriharikota.

This will be ISRO’s second launch in the current calendar after the successful launch of XPoSAT from Sriharikota on January 1 in PSLV’s 60th flight.


About the Mission

  • In its 16th mission, the GSLV aims to deploy the INSAT-3DS meteorological satellite into the Geosynchronous Transfer Orbit (GTO).
  • Subsequent orbit-raising manoeuvres will ensure the satellite is positioned in a geo-stationary orbit.
  • Mission objectives: The mission’s primary objectives are to
    • monitor Earth’s surface
    • carry out oceanic observations and its environment in various spectral channels of meteorological importance
    • 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
    • to provide satellite aided search and rescue services

INSAT-3DS Satellite 

  • INSAT-3DS Satelliteis a follow-on mission of Third Generation Meteorological Satellite from geostationary orbit.
  • It is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning.
  • The satellite will augment the Meteorological services along with the presently operational INSAT-3D and INSAT-3DR satellites.

About GSLV

  •  GSLV is a three-stage 51.7 m long launch vehicle with a liftoff mass of 420 tonnes.
    • First stage (GS1) comprises a solid propellant (S139) motor having a 139-tonne propellant and four earth-storable propellant stages (L40) strapons, each carrying 40 tonnes of liquid propellant.
    • Second stage (GS2) is also an earth-storable propellant stage loaded with 40-ton propellant.
    • Third stage (GS3) is a cryogenic stage with a 15-ton propellant loading of liquid oxygen (LOX) and liquid hydrogen (LH2).
    • During the atmospheric regime, the satellite is protected by Ogive payload fairing.
  • GSLV can be used to launch a variety of spacecraft capable of performing communications, navigation, earth resource surveys, and any other proprietary mission.
