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.

Jan 7: India’s monetary authority allowed banks to offer foreign-currency transactions outside of local market hours, a move aimed at boosting trading volumes at home.

Interbank deals, as well as those with customers in and outside India, can be undertaken by banks or their overseas branches and units at all times, the Reserve Bank of India said in a statement late Monday. It stopped short of saying whether the timing of the onshore over-the-counter market has been extended from the current 9 a.m. to 5 p.m.

The move is in line with recent recommendations to reverse the trend of the partially convertible rupee being traded more abroad than in India. London has overtaken Mumbai to become the top center for trading the rupee, adding to a sense of urgency among local authorities to deepen the onshore market.

Average daily volumes for rupee in the U.K. soared to $46.8 billion in April, a more than fivefold jump from $8.8 billion in 2016, according to a survey from the Bank for International Settlements published in September. That exceeded the $34.5 billion recorded in India.

Analysts say more trading abroad could amplify volatility in the domestic market and reduce the effectiveness of policy actions.

India’s decision comes as the London Stock Exchange Group Plc has started asking market participants if they want the bourse to function fewer hours, signaling it’s open to an argument driven by changing trading patterns and calls for a better work-life balance.

New Delhi, Jun 14: Petrol price on Sunday was hiked by a record 62 paise per litre and that of diesel by 64 paise as oil companies for the eighth day in a row adjusted retail rates in line with cost since ending an 82-day hiatus in rate revision.

Petrol price in Delhi was hiked to Rs 75.78 per litre from Rs 75.16 while diesel rates were increased to Rs 74.03 a litre from Rs 73.39, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

The 62 paise a litre increase in petrol and 64 paise hike in diesel price is the highest surge in rates since the daily price revision was started in June 2017.

This is the eighth daily increase in rates in a row since oil companies on June 7 restarted revising prices in line with costs, after ending an 82-day hiatus.

In eight hikes, petrol price has gone up by Rs 4.52 per litre and diesel by Rs 4.64 -- a record increase in rates in any eight days since the daily price revision was introduced.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL), instead of passing on the excise duty hikes to customers, adjusted them against the fall in the retail rates that was warranted because of international oil prices falling to two-decade lows.

The government had first raised excise duty on petrol and diesel by Rs 3 per litre each on March 14 and then again on May 5 by a record Rs 10 per litre in case of petrol and Rs 13 on diesel. The two hikes gave the government Rs 2 lakh crore in additional tax revenues.

State-owned fuel retailers IOC, BPCL and HPCL had frozen petrol and diesel prices since March 16, as if anticipating the government move and set off gains they accrued from continuing drop in international oil prices against the excise duty hike.

They, however, promptly passed the increase in local sales tax or VAT by state governments such as Rs 1.67 increase in VAT on petrol and Rs 7.10 in diesel by the Delhi government on May 4.

The total incidence of excise duty on petrol has risen to Rs 32.98 per litre and that on diesel to Rs 31.83. The excise tax on petrol was Rs 9.48 per litre when the Narendra Modi government took office in 2014 and that on diesel was Rs 3.56 a litre.

The government had between November 2014 and January 2016 raised excise duty on petrol and diesel on nine occasions to take away gains arising from plummeting global oil prices.

In all, duty on petrol rate was hiked by Rs 11.77 per litre and that on diesel by 13.47 a litre in those 15 months that helped government's excise mop up more than double to Rs 2,42,000 crore in 2016-17 from Rs 99,000 crore in 2014-15.

It cut excise duty by Rs 2 in October 2017 and by Rs 1.50 a year later. But it raised excise duty by Rs 2 per litre in July 2019.

It again raised excise duty on March 14 by Rs 3 per litre.

New Delhi, Mar 29: The Centre on Sunday asked state governments and Union Territory administrations to effectively seal state and district borders to stop movements of migrant workers during lockdown, officials said.

During a video conference with Chief Secretaries and DGPs, Cabinet Secretary Rajiv Gauba and Union Home Secretary Ajay Bhalla asked them to ensure that there is no movement of people across cities or on highways as the lockdown continues.

"There has been movement of migrant workers in some parts of the country. Directions were issued that district and state borders should be effectively sealed," a government official said.

States were directed to ensure there is no movement of people across cities or on highways.

Only movement of goods should be allowed.

District Magistrates and SPs should be made personally responsible for implementation of these directions, the official said.

Adequate arrangements for food and shelter of poor and needy people including migrant labourers be made at the place of their work, the official said.
