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.

New Delhi: Rajiv Memani, the chairperson of Ernst and Young India, expressed sadness that no one from the firm attended the employee's funeral, saying it was "alien to our culture" and that the individual had supposedly died from extreme work pressure. Memani, who has been subject to intense criticism on social media for what he perceives to be a hostile work environment, expressed his profound sadness for the untimely death of Anna Sebastian Perayil in a post on LinkedIn.
"Although nothing can completely fill the gap in the family's lives, I have sent them my sincerest sympathies. I sincerely apologize for our absence from Anna's burial. This is not at all representative of our culture. Memani said, "It has never happened before and it won't happen again." He also emphasized that he would not stop until the objective of "nurturing a harmonious workplace" was achieved.
Clarifying further he said, “Creating a healthy work environment has always been very important to us, and we place the utmost value on our employees' well-being."I want to reaffirm that our people's welfare is my first priority, and I will personally fight for this goal.”
On July 20, Anna Sebastian Perayil, an employee of E&Y since March, passed away. This week, the incident came to light due to the widespread distribution of her mother Anita Augustine's open letter to the corporation, in which she claimed that Anna gave in to "work pressure".
Augustine stated that her daughter's funeral was attended by no one from the company in question. "I contacted her managers following her burial, but I didn't hear back. In the letter, she said, "How can a company that claims to uphold human rights and values fail to stand by one of its own in their last moments?"
As a result of his denial that “work pressure" was the cause of the Pune woman's death, Memani came under fire on social media, according to an Indian Express article.
The Center started looking into what happened before Anna passed away as the matter escalated in urgency. Shobha Karandlaje, the minister of state for labor, announced on Thursday that a comprehensive inquiry into the claims of a hazardous and exploitative workplace was under progress.
