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.

Punishment for those disrupting assembly proceedings, warns Speaker UT Khader
Belagavi: Speaker U.T. Khader on Friday warned that members who disrupt Assembly proceedings by talking in their seats during debates will be made to sit in the House for an entire day as a disciplinary measure.
The warning came after the Question Hour, when Deputy Leader of the Opposition Arvind Bellad was permitted to initiate a discussion on the development of North Karnataka.
At this point, expelled BJP MLA Basanagouda Patil Yatnal objected, stating that he had been seeking a debate for the past three days but had not been given an opportunity.

Responding to the objection, Speaker Khader said Bellad had already been granted permission and assured Yatnal that he would be allowed to speak at the next opportunity. He noted that even as a serious discussion was underway, several MLAs were speaking among themselves with their microphones on, disrupting the proceedings.
Expressing displeasure over the conduct of members, Khader likened the situation to football, where players receive red, yellow, or white cards for violations. Similarly, he said, the Assembly issues warning cards to members who disturb the House. If they fail to correct themselves despite repeated warnings, they would be required to remain seated in the Assembly hall for a full day as punishment, he stated.
