Indian Space Research Organisation (ISRO) on Saturday successfully launched meteorological satellite INSAT-3DS on February 17 with the GSLV-F14/INSAT-3DS mission from SDSC-SHAR, Sriharikota. This will help in enhancing the weather forecast.
This was ISRO’s second success in the current calendar after the launch of XPoSAT from Sriharikota on January 1 in PSLV’s 60th flight.
GSLV-F14/INSAT-3DS mission LAUNCH
The GSLV-F14 - blasted from the second launch pad - was the 16th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV). This was the seventh operational flight of a GSLV with an indigenous cryogenic state. The 51.7 m tall rocket with a lift-off mass of 420 tonnes, with indigenous cryogenic stages, placed the INSAD-3DS satellite weighing 2,274 kg into a Geosynchronous Transfer Orbit. The whole mission lasted 1123.06 seconds at an altitude of 253.53 km.
S Somanath, Chairman, ISRO, after the launch, said, “I am very happy to announce the successful accomplishment of the mission GSLV-F14/INSAT-3DS. The spacecraft has been injected in to a very good orbit. The injection conditions were as expected, and we also noted that the vehicle has performed very well. INSAT-3DS is the next generation weather satellite with improved capabilities over the present INSAT series - INSAT 3D and INSAT 3DR - which is there in the orbit.”
INSAT-3DS will augment the capability of observation of various atmospheric parameters like information related to weather , he said from the Mission Control room.
The current mission is fully funded by the Ministry of Earth Sciences, says a release from ISRO.
In its 16th mission, the GSLV deployed 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.
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 and to provide satellite aided search and rescue services, the release said.
INSAT-3DS
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 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, the release said
Various departments of the Ministry of Earth Sciences (MoES), such as the India Meteorology Department, National Centre for Medium-Range Weather Forecasting, Indian Institute of Tropical Meteorology, National Institute of Ocean Technology, Indian National Center for Ocean Information Services and various other agencies and institutes will be using the INSAT-3DS Satellite data to provide improved weather forecasts and meteorological services.
GSLV-F14
GSLV is a three-stage 51.7 m long launch vehicle with a liftoff mass of 420 tonnes. The 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.
The second stage (GS2) was also an earth-storable propellant stage loaded with 40-ton propellant. The third stage (GS3) was a cryogenic stage with a 15-ton propellant loading of liquid oxygen (LOX) and liquid hydrogen (LH2).
GSLV can be used to launch a variety of spacecraft capable of performing communications, navigation, earth resource surveys, and any other proprietary mission, the release said.
