GSLV-F14/INSAT-3DS MISSIONHome / GSLV-F14/INSAT-3DS MISSION
February 8, 2024
The launch of the GSLV-F14/INSAT-3DS mission is set for Saturday, February 17, 2024, at 17:30 Hrs. IST from SDSC-SHAR, Sriharikota. In its 16th mission, the GSLV aims at deploying the INSAT-3DS meteorological satellite into the Geosynchronous Transfer Orbit (GTO). Subsequent orbit-raising maneuvers will ensure that the satellite is positioned in a Geo-stationary Orbit.
GSLV-F14
Geosynchronous Satellite Launch Vehicle (GSLV) is a three-stage 51.7 m long launch vehicle having a liftoff mass of 420 tonnes. The first stage (GS1) comprises a solid propellant (S139) motor having 139-ton propellant and four earth-storable propellant stages (L40) strapons which carry 40 tons of liquid propellant in each. 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.
INSAT-3DS
INSAT-3DS Satellite is a follow-on mission of Third Generation Meteorological Satellite from Geostationary Orbit. GSLV-F14/INSAT-3DS mission is fully funded by the Ministry of Earth Sciences (MoES). 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.
Various departments of the Ministry of Earth Sciences (MoES) such as the India Meteorology Department (IMD), National Centre for Medium-Range Weather Forecasting (NCMRWF), Indian Institute of Tropical Meteorology (IITM), National Institute of Ocean Technology (NIOT), Indian National Center for Ocean Information Services (INCOIS) and various other agencies and institutes will be using the INSAT-3DS Satellite data to provide improved weather forecasts and meteorological services.
The primary objectives of the mission are:
  • To monitor Earth’s surface, carry out Oceanic observations and its environment in various spectral channels of meteorological importance.
  • To 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 (DCPs).
  • To provide Satellite Aided Search and Rescue services.

Which satellite is the one that is going to have purely electric propulsion for the first time by ISRO, I heard that it would launch soon

Excellent launch, congrats to ISRO! I wish they would have been more precise and forthright about the next scheduled launches, instead of a general 'see you at the next launch campaign soon' kind of message. When is the next PSLV, SSLV? The next GSLV Mk2 is of NISAR in March-April, but there is likely at least one mission before that, probably SSLV. It would be nice to know more about it!
