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 18: Asha Devi, the mother of the 2012 Delhi gang-rape victim, on Saturday slammed senior lawyer Indira Jaising for her suggestion that she should forgive her daughter's rapists.

"Who is Indira Jaising to give me such a suggestion? The whole country wants the convicts to be executed. Just because of people like her, justice is not done with rape victims," Asha Devi said here.

"Cannot believe how Indira Jaising even dared to suggest this. I met her many times over the years in Supreme Court, not even once has she asked for my well being and today she is speaking for the convicts. Such people earn their livelihoods by supporting rapists, hence rape incidents do not stop," she added.

Asha Devi further accused Jaising of using "the garb of human rights" to make a living.

'People like her keep earning money under the garb of human rights. I do not need her suggestions... Just because of people who think like her incidents like rape keep happening, she is a disgrace to women," she said.

Earlier yesterday, Indira Jaising, through a tweet, had urged Asha Devi to forgive the perpetrators and had used the example of Congress interim president Sonia Gandhi, who had forgiven Nalini, one of the convicts who was given the death penalty by the courts.

"While I fully identify with the pain of Asha Devi I urge her to follow the example of Sonia Gandhi who forgave Nalini and said she did not want the death penalty for her. We are with you but against the death penalty," Jaising's tweet read.

New Delhi, Feb 10: The government is set to privatise Central Electronics Ltd, a CPSE under the Department of Science and Technology, by selling its 100% stake with management control and has invited the Expression of Interest for the same by March 16.

The selected bidder will be required to lock in its shares for a period of three years during which it cannot undertake the sale of its stake in CEL, the PIM (Preliminary Information Memorandum) said.

"The government of India has 'in-principle' decided to disinvest 100 per cent of its equity shareholding in CEL (which is equivalent to 100 per cent of the total paid up equity share capital of CEL) through Strategic Disinvestment with transfer of management control (Strategic Disinvestment or Transaction)," DIPAM, the Disinvestment Department, said.

The process for the transaction has been divided into two stages, namely, Stage I and Stage II.

After BPCL and Air India, this is yet another CPSE which government is slated to privatise if it gets offers from bidders.

The government has set a challenging target of Rs 2.1 lakh crore disinvestment proceeds from CPSE sell-offs and IPOs, OFSs (Offer for sale) in the next fiscal and it going out all guns blazing to meet that target after revising this fiscal target of Rs 1.05 lakh crore to Rs 65,000 crore.

The Interested Bidders (which can also include employees of CEL) must have a minimum net worth of Rs 50 crore as on March 2019. DIPAM has released complete invitation Preliminary Information Memorandum (PIM) of CEL. Resurgent India Limited is the advisor to the Transaction.

CEL is a pioneer in the country in the field of Solar Photovoltaic (SPV) with the distinction of having developed India's first Solar cell in 1977 and first Solar panel in 1978 as well as commissioning India's first solar plant in 1992.

More recently, it has developed and manufactured the first crystalline flexible solar panel especially for use on the passenger train roofs in 2015.

Its solar products have been qualified to International Standards IEC 61215/61730. CEL is further working on development of a range of new and upgraded products for signaling and telecommunication in the railway sector.

In the SWOT analysis of the CPSE, DIPAM has stated under weakness that "the company has weak financial loss due to past losses, high manufacturing cost and non payment of dues by state nodal agencies affecting the financial position of the company".

The CPSE has adequate land for expansion, the SWOT analysis said adding "the CPSE faces threat of dumping of solar cells at very low rates which makes solar PV manufacturing industry unviable".

Entry of new players in the market for solar products and railway signalling systems also is cited as a threat.

Indore, Feb 3: Senior Congress leader Digvijaya Singh on Sunday attacked the Centre for conferring the Padma Shri on Pakistan-origin singer Adnan Sami, who became an Indian citizen in 2016.

Addressing "Save the Constitution, Save the Country" rally here in Madhya Pradesh, Singh said Sami's father had "pounded India with bombs" when he was serving with the Pakistani Air Force (PAF).

"Since Sami is an artist who has come from Pakistan, I had recommended his case to the Indian government for citizenship. He has got Indian citizenship under the Modi government," the Congress leader said, adding that he never made any recommendation to the government for conferring Padma Shri on Sami.

He said Sami's father had "dropped bombs against us" while flying a Pakistan Air Force combat plane.

"In contrast, Indian Army officer Sanaullah of Assam, who had fought against the enemy, was sent to a detention camp for failing to show documents (during the Assam NRC exercise). This is the citizenship law of the Modi government," he said.

Sami, born in London to a Pakistani Air force veteran, applied for Indian citizenship in 2015 and became a citizen of the country in January 2016.

He was one of the 118 people chosen for the Padma Shri awards by the Centre last month.
