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.

Jan 27: Bollywood Film Director Anurag Kashyap, who has been vocal about his political views on social media, slammed Union Minister Amit Shah and accused him of being 'cheap'.

"How timid our Home Minister is. Its own police, its own goons, its own army and security increases and invades unarmed protestors. Amit Shah has crossed the extent of cheapness and inferiority. History will spit on this animal," Kashyap tweeted.

The film director has taken an active part in the anti-Citizenship Act protest rallies and was against the Jawaharlal Nehru violence. He also came in support of his contemporary Deepika Padukone when the latter faced backlash for showing up at JNU in support of the students.

New Delhi, Jun 25: The Supreme Court on Thursday asked the Centre and the CBSE to issue fresh notification in connection with Class 12 exams, clarifying the option between internal assessment and exams later.

The observation from the top court after it was informed that the CBSE has decided to cancel the remaining board exams for Class 10 and Class 12.

A bench comprising Justices AM Khanwilkar, Dinesh Maheshwari and Sanjiv Khanna asked the Centre to clarify the issue of taking the option between internal assessment and exams later.

"Clarify the date of results," said the bench, noting that the CBSE will have to submit a fresh draft notification cancelling class 12 Board exams and affidavit on Friday morning, before the top court continues to hear the matter again at 10.30 a.m.

The apex court also sought clarity on the beginning of the new academic year.

It told Solicitor General Tushar Mehta, representing the Centre, that the CBSE is willing to conduct exams when the situation is conducive, but this may vary from state to state. "Will the decision be taken by a central authority or will the state government take the decision? How are you going to deal with that situation?"

Mehta replied that the decision must be taken according to the situation. To this, the bench said should not the solution be pan-India?

"You have not said when you will decide on this issue, and when you will take stock of these things. Some time frame will have to be given," noted the bench.

Continuing its queries, the bench said: "What about state regional board exams... the CBSE does not hold all the exams. The state Board is also there."

Mehta replied that the instructions from the controller of examinations are that exams are controlled centrally. "State boards assist the CBSE," he replied.

The bench observed that the government should modify the draft notification and include the state board issue. "Clear the stand that decision will be taken at the central level and not at the state level... other courses will have to be delayed till CBSE exam results come out," it said.

Mehta replied the assessment results will be published now, and if a student wants to opt to give the exam, then that will be conducted later. The top court asked Mehta to bring this on record and redraft the notification.

New Delhi, Feb 5: Taking on Delhi Chief Minister Arvind Kejriwal after Shaheen Bagh shooter Kapil Baisala was identified as an AAP worker by police, BJP chief J P Nadda on Tuesday said it exposed the party and Kejriwal who were playing with the country's security.

The Aam Aadmi Party hit back, questioning the police investigation.

In a series of tweets, Nadda said people of the country and Delhi today have seen the "dirty face" of AAP.

"For political longing, Kejriwal and his people even sold the security of the country. Earlier, Kejriwal used to insult the Army and advocate terrorists, but today relations with those who carry out their terrorist activities came to light," he said.

Nadda said he wanted to make it clear to Kejriwal that this country is bigger than any election, any government, and "this nation will not forgive those who play with its security. Kejriwal and his entire team have been exposed. The people of Delhi will give a befitting reply".

He claimed the entire country has seen "photos of Imam Hussain, the MLA and former minister of the Delhi government, with a radical terrorist organisation, PFI".

Days before Delhi goes to polls, police claimed that Baisala is a member of the Aam Aadmi Party. They said Baisala joined the party in early 2019 along with his father.

Police said it had photos of Baisala purportedly joining AAP along with his father Gaje Singh last year.

AAP's Rajya Sabha MP Sanjay Singh alleged that photos which were part of investigation were leaked to the BJP. He also said the party will approach the Election Commission to raise this issue, which has cropped up four days before the polling date.

"On whose instance, the police is giving statement? How did the photos which were part of the investigation reach the BJP? Before the news came out, Manoj Tiwari in the morning stated that the accused was from AAP. How did Manoj Tiwari get this news," Singh questioned in a press conference.

Union minister and BJP's in-charge for the Delhi polls, Prakash Javadekar, in a press conference alleged that "their (AAP's) designs are very clear from the beginning and they are trying every trick".

The whole conspiracy of AAP is to "divide society, cause fear in a community and create a vote bank," he charged.

Javadekar also claimed that photos of Baisala were recovered by police from his mobile phone although they were erased.

He also claimed that Baisala and his father were welcomed by Sanjay Singh at their joining of AAP.

"This proves AAP misleads youth and pushes them on the wrong path. AAP's strategy is to divide two communities, they want to instigate riots in Delhi," Javadekar alleged.

He further alleged that AAP leader Sanjay Singh had said violence would take place in Delhi. Their "conspiracy has been exposed by Delhi Police," he claimed.

"We condemn this politics of AAP," he said.

Javadekar also claimed this was "not an isolated incident" as AAP member Amanatullah Khan made a "very provocative speech" and the party supported Shaheen Bagh and did not give permission for the prosecution of members of the "tukde-tukde gang".

He hinted the BJP could approach the Election Commission against AAP over the issue.
