IRNSS 1C launch postponed due to technical reasons

The launch of IRNSS 1C,the third of seven satellites in the series to put in place India's navigation system on par with US' Global Positioning System, has been postponed following a technical snag and the launch date would be announced later, the space agency said today.
"The launch of IRNSS 1C on board PSLV C 26 has been postponed due to some technical reasons. The new date of launch would be announced later," ISRO spokesman Deviprasad Karnik told PTI.
Asked about the reasons for the postponement, a senior ISRO official said, "The rehearsal of the launch was done last night. We have observed a small anomaly. A particular item was not functioning properly."

"After some brainstorming, we decided that all the tests would be done to ensure perfection before launch.The defective item will be replaced. We have to open the heat shield and work, so it will require at least two to three days," he said.
PSLV C26 was scheduled to be launched with India's navigation satellite IRNSS 1C from the spaceport of Sriharikota at 1.56 AM on October 10, whose countdown was to begin tomorrow.
Earlier today, ISRO had said in Bangalore that the Oct 10 launch had been deferred by a week 'due to an observation in the telemetry system.'

IRNSS 1C with a lift-off mass of 1,425.4 kg was earlier scheduled to take off on board the 28th flight of India's rocket PSLV-C26 at 1.56 am on October 10 to be shot into a sub Geosynchronous Transfer Orbit (sub GTO).

As part of its aspirations to build a regional navigational system equivalent to Global Positioning System of the US, ISRO plans to send seven satellites to put in place the Indian Regional Navigational Satellite System (IRNSS).
The first two satellites in the series, IRNSS 1A and IRNSS 1B were launched from Sriharikota on July 1, 2013 and April 4 this year respectively.
IRNSS' applications include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management.
