India successfully launches communication satellite in textbook style

August 27, 2015

Sriharikota (Andhra Pradesh), Aug 27: India successfully launched its communication satellite GSAT-6, which has several strategic applications, in textbook style on Thursday using its heavy rocket geosynchronous satellite launch vehicle (GSLV-D6).gslv6

The GSLV rocket, with a cryogenic engine, slung the satellite in a geosynchronous transfer orbit (GTO) from where it would be taken up to its final geostationary orbit.

The successful flight of GSLV rocket gives the Indian space programme a much-needed booster as getting the more-efficient cryogenic engine (which provides more thrust for every kilogram of propellant burnt) right is important for its future space programmes.

Indian space scientists have spent around two decades in conceiving the cryogenic technology and spent around Rs.400 crore in developing it.

Precisely at 4.52 p.m., the Geosynchronous Satellite Launch Vehicle-Development 5 (GSLV D6) rose from the second launch pad here at Satish Dhawan Space Centre.

The 49.1 metre tall rocket weighing 416 tonnes slung the 2,117 kg GSAT-6 communication satellite in the geosynchronous transfer orbit (GTO) around 17 minutes into the flight.

As the whole mission concluded successfully, ISRO scientists at the mission control centre were visibly happy, back-slapping and hugging each other once the rocket ejected the GSAT-6 satellite into the intended orbit.

Speaking about the launch, ISRO chairman A.S.Kiran Kumar said: "Today's performance of launch vehicle was normal. The intricacies of cryogenic engine has been understood."

This is the first successful GSLV rocket launch that placed a satellite in orbit in Kiran Kumar's tenure.

The Indian space agency flew the GSLV rocket with its own cryogenic engine for the second time on Thursday after the successful launch of a similar rocket in January 2014 that put into orbit GSAT-14.

This was the second mission of GSLV during the last five years after two such rockets failed in 2010.

One of the GSLV rockets flew with Indian cryogenic engine and the other one with a Russian engine.

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 is the liquid fuel and the third is the cryogenic engine.

For the country, ISRO's perfection of cryogenic engine technology is crucial as precious foreign exchange can be saved by launching communication satellites by itself.

Currently ISRO flies its heavy communication satellites by European space agency Ariane.

ISRO officials told IANS earlier that the country pays around $85-90 million or around Rs.500 crore as launch fee for sending up a 3.5 tonne communication satellites. The cost of satellite is separate.

The ISRO can send smaller communication satellites - weighing around two tonnes - till such time it gets ready an advanced GSLV variant-GSLV-Mark III- that can lug satellites weighing around four tonnes.

The space agency will be launching satellites like GSAT-7, 9 using a similar rocket.

One of the notable aspect of the successful launch is the rocket's weight lift capacity. The current GSLV rocket that ISRO flies has a carrying capacity of around 2.2 tonnes.

Earlier attempts to carry slightly over two tonne satellite ended in partial/total failures.

The GSAT-6 is India's 25th geostationary communication satellite and twelfth in the GSAT series.

Five of GSAT-6's predecessors were launched by GSLV during 2001, 2003, 2004, 2007 and 2014 respectively.

After its commissioning, GSAT-6 will join the group of India's other operational geostationary satellites.

The satellite provides communication through five spot beams in S-band and a national beam in C-band for strategic users.

One of the advanced features of GSAT-6 satellite is its S-Band Unfurlable Antenna of six metre diameter - the largest satellite antenna realised by ISRO. This antenna is utilised for five spot beams over the Indian mainland, which exploit the frequency reuse scheme to increase frequency spectrum utilisation efficiency.

The satellite's life expectancy is nine years.

New Delhi, May 4: Rebutting the Congress' criticism, the BJP said on Monday that the railways has subsidised 85 per cent of ticket fare for special trains being run for migrant workers and the state governments have to pay the remaining 15 per cent.

The ruling party also accused the Congress of promoting indiscriminate movement of people which, it said, would lead to "faster spread" of coronavirus infection "just like we saw in Italy", and asked if this is what Sonia Gandhi wants.

The counter-charge from BJP leaders, including its spokesperson Sambit Patra and information technology department in-charge Amit Malviya, came after Congress president Sonia Gandhi hit out at the central government for making migrants pay for their train fare and asked her party's state units to pick the tab.

Congress leader Rahul Gandhi also took a swipe at the railways, saying, on one hand, it is seeking ticket fare from people stranded in various states while on the other it is donating Rs 151 crore to the PM-CARES Fund.

Responding to him, Patra said, "Rahul Gandhi ji, I have attached guidelines of MHA which clearly state that 'No tickets to be sold at any station'. Railways has subsidised 85% & state govt to pay 15%. The state govt can pay for the tickets (Madhya Pradesh's BJP govt is paying). Ask Cong state govts to follow suit," Patra tweeted.

The BJP leader further clarified that for each 'Shramik Express', special trains being run for migrants to take them back to their native places during the lockdown, about 1,200 tickets to the destination are handed by the railways to the state government concerned.

State governments are supposed to clear the ticket price and hand over the tickets to workers, he said.

He said the BJP government in Madhya Pradesh is doing so and asked Rahul Gandhi to tell the Congress-ruled states to follow suit.

Hitting out at Sonia Gandhi, Malviya tweeted, "Congress is obviously upset at how well India has handled Covid. They would have ideally wanted a lot more people to suffer and die. Promoting indiscriminate movement of people would lead to faster spread of infection, just like we saw in Italy. Is this what Sonia Gandhi wants?"

BJP MP Subramanian Swamy claimed that migrant workers returning home will not have to pay money as the rail travel will be free from now onwards.

"Talked to Piyush Goyal office. Govt will pay 85% and State Govt 15%. Migrant labour will go free. Ministry will clarify with an official statement," he tweeted.

New Delhi, Mar 7: Bhim Army chief Chandrashekhar Azad has taunted Bahujan Samaj Party chief Mayawati saying that she has lost her way. He also said that one will have to work for the larger interest of the society to bring about equality. Only the speeches cannot improve the condition of the Dalits, their participation in power must increase.

In an interview with media persons, Chandrashekhar said: "Members of minority community, Dalits and backward classes are being targeted in the country. Their rights are being taken away. Our workers want that they too should get equal share in political power. Keeping this in mind, we are going to form a new political party on March 15. Their (Dalits) issues will have to be raised. Mere speeches will not work for Bahujan society, one has to raise voice in their favour. They should get a share in power."

On the question that how he would find a foothold in view of large political base of the BSP, Chandrashekhar said, "We are not looking for an alternative. Look at the crores of Muslims, Dalits, members of backward community and minorities. We have to protect their interests. We have a large organisation in the state. Our Bharat Bandh was also successful".

On the question that with which party he will forge an alliance in 2022 after forming his party on March 15, Chandrashekhar said: "When we are forming our party then we don't need to go seeking alliance with anyone. Our party will be formed on the basis of some principles. Whoever will find it suitable will come close to us".

On meeting with Yogi government's former minister Om Prakash Rajbhar, he said that Rajbhar is not a controversial person. He is a big backward leader. He raises voice in favour of the backwards in the Assembly. He also supported us when I was in jail. We talked about how to stop the BJP and will take all necessary steps to prevent the BJP from coming back to power.

When asked why he had several run-ins with the police, Chandrashekhar said: "Ask this question to the police. Have I broken any law? Am I not a citizen of this country? There is no freedom of speech in the Yogi government. This is happening at the behest of the government. We are just opposing it".

Talking about the CAA, NRC and the NPR, he said: "We will not stage protest because the government does not want it. Any law which is wrong in our view will be opposed. This is a secular country. The CAA will divide the country. If there is anything against the Indian Constitution, we will raise our voice. Laws will not be allowed to be made on the basis of religion".
