Sriharikota (Andhra Pradesh):29 /3/18:India on Thursday successfully launched the GSAT-6A satellite that would provide mobile communication facilities, using its heavy rocket Geosynchronous Satellite Launch Vehicle (GSLV-F08), in a copy book style.
The GSLV-MkII rocket slung the satellite in a geosynchronous transfer orbit (GTO) from where it would be taken up to its final geostationary orbit by three orbit raising manoeuvre
Precisely at 4.56 p.m., the GSLV rocket ascended into the sky from the second launch pad here at Satish Dhawan Space Centre and the 49.1 metre tall rocket, weighing 415.6 tonne, slung the two tonne satellite into the intended orbit 17.46 minutes into its flight.The purpose of the satellite is to provide mobile communication applications in S-band in five spot beams and C-band in one beam during its 10-year life spanThe Indian Space Research Organisation (ISRO) said that the GSAT-6A was similar to the GSAT-6 put into orbit in 2015.
The GSLV is a three stage/engine rocket. The core of first stage is fired with solid fuel while the four strap-on motors by liquid fuel. The second stage is the liquid fuel-propelled and the third is the cryogenic engine.
According to ISRO, two improvements — induction of high-thrust Vikas engine and electromechanical actuation system — have been made in the rocket’s second stage this time around.
One of the crucial rocket engines is the cryogenic engine, designed and developed by ISRO, and more efficient than the other two variants as it provides more thrust for every kilogram of propellant burnt.According to the latest Economic Survey, foreign exchange earnings of India from export of satellite launch services increased noticeably in 2015-16 and 2016-17 to Rs 394 crore and Rs 275 crore from Rs 149 crore in 2014-15
