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, Jan 20: Union Finance Minister Nirmala Sitharaman on Sunday said the kind of cleaning in the system that the BJP-led government had to carry out after coming to power in 2014 was "unbelievable" and it undertook the exercise without any grudge or worry.

Between 2014-16, there were a lot of questions as to why reforms did not come fast and there were comments that the government was incapable of bringing them, she said delivering the Nani Palkhivala Memorial lecture on "Road Map to $5 Trillion Economy" here.

Pointing out that there were allegations and criticism that the government wants to do something but it did not, Sitharaman said, "I am fully willing to buy that." She recalled that Prime Minister Narendra Modi often said he did not believe in incremental changes and the country needed good transformational change. The stage in which India is today, it cannot have little marginal increments, but good transformational change.

"But still one might say in the last five years the government never did. That can be a critical analysis and I am fully willing to buy that. Because post-2014 the kind of cleaning up the government had to do was unbelievable and we undertook that exercise without a grudge without a worry.. we had to do it and it is part of the game," she said. Elaborating, Sitharaman said states have their own views on Land Acquisition Bill and the government could not have done anything because land, after all, is with them.

Commenting on the topic 'Road Map to $5 trillion economy,' she said quoting Prime Minister Narendra Modi's comments, the government would take the route "Sarkar ka abhaav nahi hona chahiye, prabhaav hona chahiye aur dabaav nahi hona chahiye."

"Abhaav and dabaav both of which are not desirable, abhaav is the inadequacy or lack of adequate presence or shortfall. You do not need a shortfall. You need a government where it should be present, where it is expected to function.", she said.

"So there should not be abhaav. Dabaav (meaning pressure) is not something you want from the government. So, you want Prabhaav. It is broadly an influence, facilitation, broadly the philosophy with which it is mandated, she said.

Noting that the government has got the mandate through the election, she said, "The mandate was spelt out in so many different ways in its manifesto. So the route towards $5 trillion is this."

"We have to be there to facilitate. We have to be there to make it easy. We have to be where you need us, where there is no policy (reforms from the government)," she said.

On the Insolvency and Bankruptcy Code (IBC) implemented by the government, the union minister said the approach of the IBC was not to shut business. "IBC takes on the approach in having some kind of resolution where all people who exploited the company do not come back through the "back door," she said.

IBC was done through better management so that the institution is alive and kicking. It is something which she wanted to carry forward from Modi 1.0 to 2.0. "The point I am trying to make on this road to $5 trillion economy is that it is not just an abstraction, this is not how I want India to be. But in micro-level too, we are coming in response to every stakeholder," she said.

Kashmir, Jan 9: US Ambassador to India Kenneth I Juster along with envoys from 15 other countries arrived in Srinagar on a two-day visit to Jammu and Kashmir on Thursday, the first visit by diplomats since the abrogation of the erstwhile state's special status in August last year.

The Delhi-based envoys arrived in Srinagar by a special chartered flight at Srinagar's technical airport where top officials from the newly carved out union territory received them, officials said.

Later in the day, they would be going to Jammu, the winter capital of the newly created Union Territory, for an overnight stay. They will meet Lt Governor G C Murmu as well as civil society members, they said.

Besides the US, the delegation will include diplomats from Bangladesh, Vietnam, Norway, Maldives, South Korea, Morocco, and Nigeria, among others.

Brazil's envoy Andre Aranha Correa do Lago was also scheduled to visit Jammu and Kashmir. However, he backed out because of his preoccupation here, the officials said on Wednesday.

Envoys from the European Union (EU) countries are understood to have conveyed that they will visit the union territory on a different date and are also believed to have stressed on meeting the three former chief ministers -- Farooq Abdullah, Omar Abdullah and Mehbooba Mufti -- who are under detention.

Officials said envoys of several countries had requested the government for a visit to Kashmir to get a first-hand account of the situation in the Valley following the August 5 decision to abrogate provisions of Article 370 and bifurcate it into two union territories, Jammu and Kashmir, and Ladakh.

This is the second visit of a foreign delegation to Jammu and Kashmir since August 5. Earlier, Delhi-based think tank International Institute for Non-Aligned Studies, a Delhi-based think tank took 23 EU MPs on a two-day visit to assess the situation in the union territory.

The government had distanced itself from the visit with Minister of State for Home G Kishan Reddy informing Parliament that the European parliamentarians were on a "private visit".
