in the news?
●
Indian Space Research Organisation has
completed all key tests on Insat-3DS satellite before the final review which
will be followed by its shipping to the spaceport in Srihari Kota, Andhra
Pradesh.
INSAT-3DS:
●
It is an advanced meteorological satellite of India configured with an
imaging System and an Atmospheric Sounder.
Launched
by:
●
It is a collaborative effort between ISRO and the India Meteorological
Organisation (IMD).
Aim:
●
It is part of a series of climate observatory satellites aimed at
enhancing climate services.
●
Comprising three dedicated Earth
observation satellites, including INSAT-3D and INSAT-3DR already in orbit.
Launch
Vehicle
-
Geosynchronous Launch Vehicle (GSLV-F14).
Significance:
●
Imaging in the Middle Infrared band to provide night time pictures of low clouds
and fog.
●
Imaging in two Thermal Infrared bands for estimation of Sea Surface Temperature
(SST) with better accuracy.
●
Higher Spatial Resolution in the Visible
and Thermal Infrared bands.
Payloads:
●
INSAT-3DR carries a multi spectral Imager,
19 channel Sounder, Data Relay Transponder and Search and Rescue Transponder.
Go
back to basics:
GSLV-F14:
●
It is a more advanced rocket utilising liquid propellant.
●
The rocket, distinguished by its higher
capacity and the use of cryogenic liquid
propellants in all three stages, presents a more complex engineering
challenge but allows for a substantially higher lift-off weight capacity.
