India’s latest communication satellite GSAT-15 successfully launched

November 11, 2015

Bengaluru, Nov 11: India’s latest communication satellite GSAT-15 was successfully launched by Ariane-5 rocket in the early hours on Wednesday from the spaceport of Kourou in French Guiana.

GSATThe European launcher blasted off at 03:04am (IST) and hurled the GSAT-15, designed to deliver telecommunications services, as well as dedicated navigation-aid and emergency services, into space in a flawless flight.

The satellite was launched into a Geosynchronous Transfer Orbit (GTO) after its co-passenger Arabsat-6B (BADR-7) was injected into space.

“Arianespace successfully launched two satellites this evening (local time): Arabsat-6B (BADR-7) for the operator Arabsat, and GSAT-15 for Isro (Indian Space Research Organisation),” Arianespace said.

GSAT-15, weighing 3,164 kg at lift-off, is a high power satellite being inducted into the INSAT/GSAT system. It carries a total of 24 communication transponders in Ku-band as well as a GPS-Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands, Isro said adding that it is the third satellite to carry GAGAN payload after GSAT-8 and GSAT-10, which are already providing navigation services from orbit.

It also carries a Ku-band beacon as well to help in accurately pointing ground antennas towards the satellite.

GSAT-15 is the 19th payload launched by Arianespace for Isro.

Speaking at Kourou, Isro Satellite Centre (ISAC) director M Annadurai said, “GSAT-15 satellite signal has been acquired by Master Control Facility at Hassan (in Karnataka). The initialisation commands are in process and the satellite health is hail and healthy.”

He said the launch of GSAT-15 will enable ISRO to provide continuity of service to Indian users in Ku-band and the navigation payload GAGAN of GSAT-15 will provide in orbit backup to ensure safety of life navigation services in civil aviation sector as well as other location based services to various services in the Indian region.

Annadurai also said other two communication satellites GSAT-17 and GSAT-18 are getting ready for launch by Ariane vehicle in the next year.

“The realisation of both the satellites are in very advanced stage.”

The launch was telecast live by Doordarshan. GSAT-15 brings in Ku-band capacity to augment as well as provide replacement to indigenous operational satellite capacity, Isro said.

“The launch of GSAT-15 will be one more step towards further strengthening the satellite navigation infrastructure and sustaining the communication infrastructure in the country,” Isro chief AS Kiran Kumar said in a recorded video message.

Indian satellite’s co-passenger Arabsat-6B, lofted for Airbus Defence and Space and Thales Alenia Space as part of a turnkey contract with Saudi Arabia-based Arabsat, was also launched by Ariane 5 VA-227.

According to Arianespace, Arabsat-6B, to be renamed BADR-7 once in orbit will provide broadcast, broadband and telecommunications services over the Middle East, Africa and Central Asia.

Ariane 5 mission had a total payload lift performance of 9,810kg. This includes the two satellites’ mass at liftoff -5,798kg for Arabsat-6B and 3,164kg for GSAT-15 - along with launcher integration hardware and Ariane 5’s dual-passenger deployment system.

The GAGAN payload in GSAT-15 provides the Satellite Based Augmentation System, through which the accuracy of the positioning information obtained from the GPS satellites is improved by a network of ground based receivers and made available to the users in the country through geostationary satellites, Isro said.

In the next few days, the MCF at Hassan will perform the initial orbit raising manoeuvres using the Liquid Apogee Motor (LAM) of the satellite to take it to its intended space home.

With the designed in-orbit operational life of 12 years, GSAT-15 will be positioned at 93.5 degree east longitude and co-located with INSAT-3A and INSAT-4B satellites.

New Delhi, Apr 23: Congress president Sonia Gandhi on Thursday accused the BJP of spreading the virus of communal prejudice and hatred in the country, asserting that "grave damage" is being done to social harmony

Addressing a meeting of the Congress Working Committee, Gandhi said it should worry every Indian and her party will have to work hard to repair this damage.

"Let me also share with you something that should worry each and every one of us as Indians. When we should be tackling the coronavirus unitedly, the BJP continues to spread the virus of communal prejudice and hatred," she said.

"Grave damage is being done to our social harmony. Our party, we will have to work hard to repair that damage," the Congress president added

Former prime minister Manmohan Singh, former Congress president Rahul Gandhi and top Congress leaders attended the meeting through video conference

This is the second time the CWC, the Congress' top decision-making body, is meeting through video-conferencing in the past three weeks ever since the lockdown was enforced to contain the coronavirus threat.

The Congress president said the coronavirus pandemic has increased disturbingly in the past three weeks and called upon the government to increase testing for it

Gandhi said she has written several times to the prime minister since the lockdown was enforced and suggested several measures and constructive cooperation

"Unfortunately, they have been acted upon only partially and in a miserly way. The compassion, large-heartedness and alacrity that should be forthcoming from the central government is conspicuous by its absence," she said

The Congress chief said the focus of the party must continue to be on successfully engaging with health, food security and livelihood issues.

She claimed that around 12 crore people have lost jobs in the first phase of the lockdown and urged the government to provide a relief package for the MSME sector, which accounts for one-third of the GDP

Gandhi called upon the government to provide food and financial security to migrants and jobless stranded at various places and were desperate to reach back home

"We have repeatedly urged PM there is no alternative to testing, tracing and quarantine. Unfortunately, testing still remains low, testing kits still in short supply," she noted

Gandhi said trade, commerce and industry have come to a virtual halt and crores of livelihoods have been destroyed.

"The central government does not appear to have a clear idea on how the situation will be managed after May 3rd. A lockdown of the present nature after that date would be even more devastating," she said

Former prime minister Manmohan said the success of the lockdown will be judged finally on India's ability to tackle COVID-19

He also said the cooperation between the Centre and states was key to success of the country's fight against coronavirus

Singh said it is necessary to focus on a number of issues in the fight against coronavirus

The fight against COVID-19 would very much depend upon the availability of resources, he noted

Rajasthan chief minister Ashok Gehlot said unless the central government comes forward to financially help states, the fight against COVID-19 will get weakened

"Unless there is a big financial package for states, how will normalcy return to states post lockdown," he asked

Chhattisgarh chief minister Bhupesh Baghel said unless the Centre rises to the occasion and provides financial assistance to states, how will the fight against COVID-19 be won

Puducherry chief minister V Narayanasamy said the Union government has not given any assistance to the states

"How will states survive in times of crisis. We are not enemies but have to act and work together," Narayanasamy said at the CWC meet.

New Delhi, May 27: Professor Johan Giesecke of the Karolinska Institute, Sweden, on Wednesday claimed that India will ruin its economy very quickly if it had a severe lockdown.

Claiming that a strict lockdown may disrupt India's economic growth, Giesecke during an interaction with Congress leader Rahul Gandhi said: "In India, you will do more harm than good with strict lockdown measures. India will ruin its economy very quickly if it had a severe lockdown."

While calling for a soft lockdown approach in India, he suggested that India has to ease restrictions one by one. It may, however, take months to completely come out of lockdown, he said.

He further criticised countries across the globe for having no post-lockdown strategy.

Emphasising on the disease, the Swedish health expert said that coronavirus is spreading like a wildfire across the world. "It is a very mild disease. Ninety-nine per cent infected people will have very less or no symptoms," he added.

Meanwhile, Ashish Jha, Director Harvard Global Health Institute and a recognised public health official, in interaction with Gandhi, called for a need to go in for an 'aggressive' COVID-19 testing to create confidence among people.

"When the economy is opened post-lockdown, you have to create confidence. There is a need for aggressive testing strategy in high-risk areas," he said.

He asserted that COVID-19 is not the last pandemic in the world, adding that "We are entering the age of large pandemics".

Jha further said that countries like South Korea, Taiwan and Hong Kong have responded the best to COVID-19 pandemic, while Italy, Spain, the US and the UK have responded the worst.

A few days ago, the Gandhi scion had interacted with former Reserve Bank of India Governor Raghuram Rajan and Nobel Prize Winner Abhijit Banerjee to discuss various issues related to the COVID-19 crisis.
