According to ISRO, The countdown for the launch of the INSAT-3DS meteorological satellite onboard a Geosynchronous Launch Vehicle has commenced.
About INSAT-3DS:
INSAT-3DS Satellite is a follow-on mission of Third Generation Meteorological Satellite from Geostationary Orbit.
Presently, meteorologists make extensive use of data generated by satellites like the INSAT-3D and INSAT-3DR (launched in September 2016, still operational).
It is fully funded by the Ministry of Earth Sciences (MoES).
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.
Weight: 2,274 kg.
Orbit: Geosynchronous Transfer Orbit (GTO).
It will be launched by using the Geosynchronous Launch Vehicle (GSLV-F14).
What is GSLV-F14?
It is a more advanced rocket utilising liquid propellant.
It is a three-stage 51.7 m long launch vehicle having a liftoff mass of 420 tonnes.
The third stage (GS3) is a cryogenic stage with a 15-ton propellant loading of liquid oxygen (LOX) and liquid hydrogen (LH2).
