INSAT-3DS: ISRO's meteorological satellite

Context

The Indian Space Research Organisation (ISRO) successfully launched the INSAT-3DS meteorological satellite onboard a Geosynchronous Launch Vehicle (GSLV).

About

About INSAT-3DS Satellite

A geostationary orbit is a high earth orbit that permits satellites to match Earth's rotation

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 would serve various departments under the Ministry of Earth Sciences including the Indian Meteorological Department (IMD).
The satellite will augment the meteorological services along with the presently operational INSAT-3D and INSAT-3DR satellites.

Objectives of the mission:

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.

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.
