India recalls GSAT-11 satellite for tests from Arianespace rocket port.
Chennai, April 25: The Indian space agency has recalled its communication satellite GSAT-11 from Arianespace's rocket port in Kourou in French Guiana, said Arianespace.
"Due to additional technical checks with the Indian Space Research Organisation’s (ISRO) GSAT-11 satellite, to be conducted from the ISRO Satellite Centre (ISAC) located in Bengaluru, the Ariane 5 launch initially planned for May 25, VA243, has been postponed," Arianespace said on Wednesday.
The GSAT-11 was planned to be launched mid May. The satellite had reached Arianespace's rocket port in March.
GSAT-11 was designed, assembled and integrated by the ISRO, and will have an estimated lift-off mass of 5,870 kg.
This advanced communications satellite is to provide multi-spot beam coverage over the Indian mainland and nearby islands, bringing significant advantages to the user community when compared with India's existing INSAT/GSAT satellite systems, Arianespace said earlier in a statement.
With its new system architecture and cutting-edge technology elements, GSAT-11 will generate a capacity of more than 12 Gbps for users from a single platform, the statement added.
It is not known what has prompted ISRO to recall its 5.8-ton satellite GSAT-11 for further tests.
It may be recalled, ISRO lost communication contact with its GSAT-6A communication satellite soon after it was put into orbit on March 29.
ISRO suspects the failure of the power systems in the satellite for the loss of communication link.
"The satellites are powered by solar panels that charge the onboard batteries. The batteries are fully charged when the satellite is loaded on to the rocket.
"Even if there is a problem with the solar panel, then the battery power should have kicked in. Here the entire power system of the satellite seems to have failed," one space expert told IANS earlier.
According to experts, the power system could have failed due to some short circuiting or arcing resulting in what is known in the space terminology 'loss of lock' or loss of contact with the ground station.
Satellites in space are locked to ground stations for tracking and other purposes.
On March 29, Indian rocket Geosynchronous Satellite Launch Vehicle (GSLV) slung GSAT-6A in its intended orbit. From there the satellite was to be taken up further to its orbital slot by firing its onboard motors.
The first orbit raising operation was successfully carried out by firing the onboard motors for around 36 minutes on March 30 morning.
The second orbit raising operation of GSAT-6A satellite was also successful as its motors was fired for about 53 minutes on March 31.
After that the communication link got snapped.
Industry experts also said there has been instances where communication link with satellites got reestablished after a break of couple of days.

Annamalai's remarks about Mumbai misconstrued for political gains, says BJP MLA
Mumbai (PTI): BJP MLA R Tamil Selvan on Monday defended party leader K Annamalai's remarks about Mumbai, saying his statements, aimed at highlighting the city's global importance, had been deliberately misconstrued for political gains.
The Shiv Sena (UBT) last week demanded that Annamalai be arrested for his remark that "Bombay is not a Maharashtra city".
While campaigning for the January 15 civic body elections last week, former IPS officer and ex-Tamil Nadu BJP president Annamalai had said, "People want a triple engine government. This is the only metro city in the country where a triple engine is possible. Modi is in Delhi, Fadnavis is the chief minister, and now Mumbai will have a BJP mayor. Mumbai is not a Maharashtra city but an international city."

Talking to reporters, Selvan, who represents the Sion Koliwada assembly constituency, said, "Our leader Annamalai described Mumbai as a city respected across the world. What he wanted to say was that Mumbai is becoming the world's number one city, mainly because of the blessings of Chief Minister Devendra Fadnavis. Be it the Metro project, road construction or the provision of services, Mumbai has emerged as an important city on the global front. Annamalai was talking in this context."
The BJP leader's words were being distorted for political gains, he said.
"How can anyone separate Mumbai from Maharashtra? Not even a prime minister will be able to do it. Annamalai did not say those words out of disrespect. He was only saying that Mumbai has a global identity," he said.
Responding to Maharashtra Navnirman Sena chief Raj Thackeray's "Rasmalai" jibe at Annamalai, Selvan said, "Raj Thackeray is a senior leader, and many respect him. I still respect him, but he should respect others as well. I am also from Tamil Nadu, but I have won the assembly elections thrice with the support of around 90,000 Marathi voters. They did not see my background."
The BJP gives tickets to people who serve the society, he said.
Selvan claimed that he had worked extensively in Maharashtra, even in rural areas, and invoked icons such as Chhatrapati Shivaji Maharaj, Dr Babasaheb Ambedkar and Lokmanya Tilak in his speeches.
In a dig at his critics, the BJP MLA said, "Now people have seen who uses foul language against our chief minister, who works for the people's welfare. We oppose such use of foul language. CM Fadnavis will take appropriate action against such people."
