Indian Space Research Organisation (ISRO) will launch meteorological satellite INSAT-3DS on February 17 with the GSLV-F14/INSAT-3DS mission set for lift off at 5.30 pm 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.

The current mission is fully funded by the Ministry of Earth Sciences, says a release from ISRO.

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.

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 and to provide satellite aided search and rescue services, the release said.


INSAT-3DS Satellite is 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. Indian Industries have significantly contributed to the making of the satellite, the release said.

Various departments of the Ministry of Earth Sciences (MoES), such as the India Meteorology Department, National Centre for Medium-Range Weather Forecasting, Indian Institute of Tropical Meteorology, National Institute of Ocean Technology, Indian National Center for Ocean Information Services and various other agencies and institutes will be using the INSAT-3DS Satellite data to provide improved weather forecasts and meteorological services.


GSLV is a three-stage 51.7 m long launch vehicle with a liftoff mass of 420 tonnes. The 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.

The second stage (GS2) is also an earth-storable propellant stage loaded with 40-ton propellant.

The 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, the release said.
