Gsat 6a satellite is successfully launched in India, to provide mobile communication facilities, using its heavy rocket Geosynchronous Satellite Launch Vehicle (GSLV-F08).
In a geosynchronous transfer orbit (GTO) the GSLV-MkII rocket slung the satellite from where it would be taken up to its ending geostationary orbit by three orbit rising man-oeuvre.
Indian Space Research Organisation (ISRO) Chairman K. Sivan said: “This is the sixth successful launch of GSLV with indigenous cryogenic engine. The GSAT-6A satellite was placed in its designated orbit specifically.””The GSAT-6A will complement GSAT-6 launched earlier. The two satellites will provide stand for advanced technologies for point-to-point communication.”
He said the GSLV rocket had major improvements to increase its performance.The induction of high-thrust Vikas engine enhances the performance capacity of the second stage by around six per cent. Sivan said the rocket has been fitted with electromechanical actuation system in the place of electro-hydraulic actuation system, adding that the electromechanical actuation system was made with ISRO developed space grade lithium-ion (Li-Ion) cells.
Specifically at 4.56 p.m., the GSLV rocket ascended into the sky from the second launch pad here at Satish Dhawan Space Center and the 49.1 metre tall rocket, weighing 415.6 tonne, slung the two tonne into the planned orbit 17.46 minutes into its flight.
The principle 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 span.
ISRO said that the GSAT-6A was related 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 Vikas engine and electromechanical actuation system — have been made in the rocket’s second stage this time around.
Crucial rocket engines designed and developed by ISRO i.e. Cryogenic engine, it is more proficient than the other two variants as it provides more power for propellant burnt.With this successful launch, India established the performance of its GSLV-MkII rocket which in future may fetch orders from third parties for launching their satellites.
India puts into orbit foreign satellites for a fee using its lighter rocket – the Polar Satellite Launch Vehicle (PSLV) as their weight is not much.Satellites launching depends on weight of the satellite – higher the weight, higher will be the revenue.
According to the latest Economic Survey, foreign exchange earnings of India from export of satellite launch services increased markedly in 2015-16 and 2016-17 to Rs 394 crore and Rs 275 crore from Rs 149 crore in 2014-15.
But, the latest news says that communication from the GSAT-6A satellite has been lost and efforts are underway to establish a link with it, the Indian Space Research Organisation said today, after maintaining an unusual silence on the health of the spacecraft. the second orbit raising operation of GSAT-6A has been successfully carried out by Liquid Apogee Motor (LAM) Engine firing for about 53 minutes the ISRO said in a statement.
The ISRO had successfully put into orbit its latest communication satellite GSAT-6A after a perfect launch of its powerful geosynchronous rocket (GSLV-F08), from its spaceport in Sriharikota in Andhra Pradesh. The satellite would help in mobile communication even from very remote locations through hand-held ground terminals.The space agency’s unusual silence regarding the satellite had lead to speculation about the health of the spacecraft.
The ISRO, which normally communicates on its website about the orbit raising operations, following the success of the first orbit raising operation, had not released any update since then.The 2140-kg communication satellite GSAT-6A is meant to help in mobile communication even from very remote locations through hand-held ground terminals.
last year, India’s mission to launch its backup navigation satellite IRNSS-1H on board PSLV-C39 ended in a failure after a technical fault on the final leg following a perfect launch.The heat shield did not separate on the final leg of the launch sequence and, as a result, IRNSS-1H got stuck in the fourth stage of the rocket said by, the ISRO.
