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.

May 7: Accusing the BJP government in Karnataka of "medieval barbarism" and treating migrants as worse than "bonded labourers", CPI(M) general secretary Sitaram Yechury on Wednesday hit out at the state's decision to stop workers from returning to their homes in different parts of the country citing requirements of the construction sector.

The Karnataka government has withdrawn its request to the railways to run special trains to ferry migrant labourers to their home states, hours after builders met Chief Minister B S Yediyurappa to apprise him of the problems the construction sector will face in case they left.

"This is worse than treating them as bonded labour. Does the Indian constitution exist? Are there any laws in the country? This BJP state government is throwing us back to medieval barbarism. This will be stoutly resisted,” Yechury said in a tweet.

The railways is running Shramik Special trains to ferry to their home towns migrants who were stranded at their places of work during the lockdown.

So far, it has run more than 115 such trains.

The Principal Secretary in the Revenue Department N Manjunatha Prasad, who is the nodal officer for migrants, had requested the South Western Railways on Tuesday to run two train services a day for five days except Wednesday, while the state government wanted services thrice a day to Danapur in Bihar. However, later, Prasad wrote another letter within a few hours that the special trains were not required. Several migrants in the city were desperate to return home as they were out of jobs and money.

Yechury also lashed out at the central government over reports that it owed states and industry Rs 3 trillion and accused the centre of shifting the burden of fighting the pandemic to the state governments.

“While shifting the entire burden of fighting the pandemic on to the State governments, Modi government is not even paying their legitimate dues. After November 2019, Centre has not paid the GST compensation dues for the rest of the financial year, i.e., March 2020.

“Modi government has the right to loot while crores of people & States are left with nothing but the right to starve?,” he tweeted.

New Delhi, Mar 12: The coronavirus pandemic could deal a crippling blow to the Indian travel and tourism industry, specially with the government suspending all visas, with the economic impact being assessed to run into thousands of crores of rupees. According to industry chamber CII, this is the one of the worst crises ever to hit the Indian tourism industry impacting all its geographical segments - inbound, outbound and domestic, almost all tourism verticals - leisure , adventure, heritage, MICE, cruise, corporate and niche segments.

The whole tourism value chain across hotels, travel agents, tour operations, destinations, restaurants, family entertainment venues and air, land and sea transportation have been hit.

In an impact assessment of the coronavirus pandemic, CII Tourism Committee said inbound foreign tourism of over USD 28 billion in value terms accounts for an average 60-65 per cent between October to March.

"As the news of the virus started picking up from November, the percentage of cancellations started going up in this segment exponentially and is reaching a peak of almost 80 per cent now in March in many Indian locations. The value at risk from this segment will be in multiples of tens of thousands of crores," the CII assessment report said.

With India cancelling all visas, the chamber said the impact "will be worse".

It further said,"The forward bookings for the inbound season of October 2020-March 2021 which should have started picking are all muted. These are showing highly discouraging signs with cancellations of important global travel marts which are marketplaces for contracting for the next season."

It further said there are reports of large scale forward cancellations from NRI segment from developed markets, which account for over 60 per cent during April to September inbound visits.

"Unless the progression of the virus stops, almost the entire value for the remainder of 2020 season is at risk," the report added.

ANAROCK Property Consultants Chairman Anuj Puri said India's hospitality sector will definitely be impacted by the announcement of a global pandemic, and the mounting numbers of confirmed coronavirus cases in the country.

"The cancellation of visas for foreigners as well as the strong advice issued to Indians to refrain from unnecessary travel will have a marked effect. This is the most unsettling healthcare crisis in recent times and hotel bookings will go south," he added.

On Indians being advised to refrain from unnecessary travel, as per the CII report almost 28 million plus Indians are estimated to have travelled outside in 2019 and there were almost 1.8 billion domestic tourist footfalls.

The holiday season of Indians -- those travelling within the country and outside -- is heavy in April-July, October and December.

"The December holiday season of 2019 took an estimated hit of almost 40-50 per cent, the holiday season of April to July 2020 is likely to take a humongous hit which could be as high as 80-100 per cent, unless there is positive news of the progression of virus decreasing," the CII assessment report said.

There are advanced cancellations and highly reduced forward booking pipelines for the holiday season. Only corporates are flying and that too only on highly essential same day travel. Most of the MNCs are advising work from home, stifling travel, it added.

On suspension of visas, MakeMyTrip Group CEO Rajesh Magow told ,"The period between February till the end of March is typically a lean period because of exam season but we are seeing a demand slowdown for the upcoming summer holiday season especially for international travel. The situation remains dynamic making it hard to quantify the actual impact on our business and industry at large."

He further said,"The decision by the government will have an impact on inbound and outbound international travel. So far there are no restrictions or advisories issued for domestic travel."

VFS Global Regional Group COO - South Asia, Middle East and North Africa, Americas Vinay Malhotra said,"While it is too early to comment on the impact of coronavirus on visa application trends, so far, our visa application processes in India continue on schedule as per the mandates of our client governments."

He also said the company is exploring steps to assuage concerns of people about visiting busy public areas due to the nature of the virus by considering discounted rates on courier return services for visa customers who want to avoid returning to the visa centres to pick up their passports.

Besides, he said,"We are also contemplating lower fees for our Visa at your doorstep service, for those customers who are requesting an alternative to visiting the centres to submit visa applications."
