INSAT-3DS

Context

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

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.
