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.

Mumbai, May 31: Shiv Sena leader Sanjay Raut on Sunday alleged that the event held in Ahmedabad to welcome US President Donald Trump in February was responsible for the spread of coronavirus in Gujarat and later in Mumbai and Delhi, which some of his delegates had visited.

Raut also hit out at the Centre saying that the lockdown was implemented without any planning, but now the responsibility of lifting the curbs was left to the states.

The Sena MP said that despite the opposition BJP's attempts to pull down the Maharashtra Vikas Aghadi (MVA) government, there was no threat to it as its survival is the 'majboori' (compulsion) of all the three ruling allies- Sena, NCP and Congress.

"It can't be denied that the spread of coronavirus in Gujarat was because of the massive public gathering held to welcome US President Donald Trump. Some of the delegates, who accompanied Trump, also visited Mumbai, Delhi, which led to the spread of the virus," Raut said in his weekly column in Shiv Sena mouthpiece 'Saamana'.

On February 24, Trump along with Prime Minister Narendra Modi had taken part in a road-show in Ahmedabad, which was attended by thousands of people. After the road- show, the two leaders had addressed a gathering of over one lakh people at Motera cricket stadium, run by Gujarat Cricket Association (GCA).

Gujarat had reported its first coronavirus cases on March 20, when samples of a man from Rajkot and a woman from Surat tested positive for the disease.

Raut said that any move to pull down the Uddhav Thackeray-led MVA government and impose President's rule in the state citing its failure to curb the coronavirus pandemic would be suicidal.

"The state had witnessed how President's rule was imposed and lifted as per will six months ago," he said.

"If the handling of coronavirus cases is the basis of imposing President's rule, then it should be done in at least 17 states, including the BJP-ruled ones. Even the central government has failed to curb the pandemic as it had no planning to fight the virus," he said.

"The lockdown was imposed without any planning and now without any plan, the responsibility of lifting it has been left to the states. This chaos will further worsen the crisis," he said.

The Sena MP said that Congress leader Rahul Gandhi has made an excellent analysis of how the lockdown has failed.

"It is shocking that people can indulge in politics by demanding President's rule in Maharashtra for the rise in the coronavirus cases," he said.

BJP MP Narayan Rane had recently met Maharashtra Governor B S Koshyari and demanded imposition of President's rule in view of the the Shiv Sena-led state government's "failure" in tackling the coronavirus pandemic. However, the BJP had later said that it was not trying to destabilise the government.

Speaking about the stability of the government, Raut said that the survival of the MVA government was the 'majboori' (compulsion) of each of the three alliance partners.

"Even if there are internal conflicts among the ruling partners, there is no threat to the government as the allies know that its survival is the 'majboori' of each one of them," Raut said.

He said that the Devendra Fadnavis-led government, in which the BJP and Shiv Sena shared power, saw internal conflicts between the ruling allies, but it completed its full five-year term.

Slamming Fadnavis, who is now the Leader of Opposition in the Legislative Assembly, for predicting downfall of the MVA government saying it will fall on its own due to its internal bickering.

"If the Fadnavis government, which witnessed deep internal conflicts between BJP and Sena, didn't fall, how can this one collapse? The Fadnavis government survived despite the (Sena) ministers carrying their resignation letters in their pockets," Raut wrote.

Fadnavis, in an online media interaction held earlier recently, said he had no intention to destabilise the MVA government and said it would collapse on its own.

"What Fadnavis means is that all attempts (of the BJP) to create discord among the three allies and break the MLAs has failed. Now the opposition hopes that something would happen among the allies and the government would be fall apart," he said.

Raut said NCP president Sharad Pawar is the prominent leader, who laid the foundation stone of the "Thackeray sarkar", and only he can predict the future of the government.

"He continues to say the government is stable and even the Congress is not going anywhere. MVA legislators are not up for sale in horse-trading. Hence, if the opposition says that the government will fall, it is wrong," he said.

Jaipur, July 13: Amid a deepening political crisis in Rajasthan where the number 2 leader of the Congress party Sachin Pilot has revolted, over 200 Income Tax (I-T) sleuths raided the residences and properties of two of Chief Minister Ashok Gehlot’s close confidants.

The Income Tax department has carried out searches at over a dozen locations linked to Congress leader Dharamender Rathore as well as jewellery firm owner Rajiv Arora, both of whom are considered close to Gehlot.

Officials said that the raids that are underway in Jaipur, Kota, Delhi, and Mumbai were done after a complaint of tax evasion was made. Under the scanner, they said, are transactions that were made outside the country.

The curious timing of the Income Tax department’s action against Gehlot’s aides has made the Congress accuse the sleuths of acting on the behest of the BJP.

Congress spokesperson Randeep Singh Surjewala tweeted: “After all, BJP's lawyers came on the field. The Income Tax Department started raids in Jaipur. When will ED arrive?”

The Congress is facing a cliffhanger in Rajasthan after the open rebellion by deputy chief minister Sachin Pilot, who on Sunday night claimed that he had the support of 30 MLAs and that Gehlot was leading a minority government in the state.

However, Congress leader Avinash Pande on Monday said 109 MLAs have signed a letter of support to the chief minister, well above the majority mark of 100. The party has issued a whip to all the MLAs, asking them to attend the Congress Legislature Party meeting at 10.30 am.
