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 15: Suspended Deputy Superintendent of J&K Police Davinder Singh had ferried Hizbul Mujahideen terrorist Naveed Babu to Jammu last year also and facilitated his return to Shopian after "rest and recuperation", officials interrogating him said here Tuesday.

"Meri mati maari gayi thi (I must have lost my mind to do what I did)," an interrogator quoted Singh as saying after the DSP failed to impress them with his theory of catching a big terrorist.

Singh was arrested last Saturday along with Naveed Babu alias Babar Azam, a resident of Nazneenpora in South Kashmir's Shopian district, and his associate Asif Ahmad.

He is believed to have taken Rs 12 lakh for smuggling the two to Chandigarh for providing them accommodation for a couple of months, officials said. The officials, who have been spending considerable time questioning Singh, said there have been many inconsistencies in his statements and everything was being crosschecked and corroborated with the confessions of captured militants who have been kept in different rooms at an interrogation centre in South Kashmir.

During questioning it emerged that Singh had taken them to Jammu in 2019 also, the officials said.

In a tone laced with sarcasm, they said the DSP was taking the militants for "rest and recuperation".

Naveed told the interrogators that they used to stay in the hilly regions to avoid the J&K police and left the areas to escape harsh winters, they said.

The official said the DSP's bank accounts and other assets were being verified by the police and papers were being collected, amid speculations that the case may be handed over to the National Investigation Agency (NIA).

Going into the service history of Singh, majority of retired and serving officials of the JKP spoken to referred to a proverb -- coming events cast their shadows long before -- to say that if action had been taken against the officer during his probation period, such things would not have happened.

Recruited in 1990 as a sub-inspector, Singh along with another probationary officer were subject of an internal enquiry where some narcotics had been seized from a truck. However, the contraband was sold by Singh and another sub-inspector, the officials recalled.

There was a move to dismiss them from the service which was stalled by an Inspector General rank officer purely on humanitarian ground and the duo was shifted to the Special Operations Group, a team of policemen engaged in counter-militancy offensive.

However, he could not last there for long and was shifted this time to the police lines only to be rehabilitated in 1997 again in the SOG.

During this period, he was posted in Budgam and is alleged to have indulged in extortion for which he was sent back to the police lines.

His proper rehabilitation began in 2015 by the then Director General of Police K Rajendra, who posted him in district headquarters of Shopian and Pulwama, the officials said.

However, after some alleged wrongdoing during his stint in Pulwama, the then Director General of Police S P Vaid transferred him in August 2018 to the sensitive Anti-Hijacking Unit in Srinagar, though the move was opposed by some other officers.

An advocate, Irfan Ahmad Mir, was driving the vehicle when they were caught by the police on National Highway in Kulgam district.

The advocate, who has also been arrested, had travelled to Pakistan five times on an Indian passport.

The function, held on a virtual platform, saw the participation of UN Secretary General Antonio Guterres and other top UN dignitaries who applauded all the leaders which included state Health Minister K.K. Shailaja for effectively tackling Covid-19.

Speaking on the occasion, Shailaja noted that the experiences of tackling Nipah virus and the two floods - 2018 and 2019 - where the health sector played a crucial role, all helped in tackling Covid-19 timely.

"Right from the time when Covid cases got reported in Wuhan, Kerala got into the track of the WHO and followed every standard operating protocols and international norms and hence, we have been able to keep the contact spread rate to below 12.5 per cent and the mortality rate to 0.6 per cent," she said.
