PM Modi congratulates ISRO for successful launch of navigation satellite IRNSS-1I

PM Modi congratulates ISRO for successful launch of navigation satellite IRNSS-1I

He lauded the team for working tirelessly to make the PSLV-C41/IRNSS-1I a success after a major GSLV mission.

The IRNSS-1I satellite is scheduled to blast off from the Satish Dhawan Space Centre in Sriharikota at 4 am on April 12.

India early on Thursday put into orbit navigation satellite IRNSS-1I, a part of Indian satellite navigation system NavIC in copy-book style. The mission from last August was a failure as the rocket's heat shield did not separate three minutes after the rocket's lift-off. In a text-book launch, about 18 minutes later, the rocket injected GSAT-6A into the geostationary transfer orbit as the ISRO scientists broke into celebrations at the mission control centre. This launch took place after 14 days of GSLV, or Geosynchronous Satellite Launch Vehicle, which had some technical difficulties and the GSAT that it had been heaving lost contact due to system failure.

The navigation payload of IRNSS-1I will transmit navigation service signals to the users.

The March 29 mission lofted India's GSAT 6A communications satellite created to provide mobile video and data services across the Indian subcontinent. "IRNSS-1A will continue to remain in orbit for messaging purposes", the ISRO spokesperson confirmed to ThePrint.

India's Polar Satellite Launch Vehicle, in its 43rd flight (PSLV-C41), successfully launched the IRNSS-1I navigation satellite from the Sriharikota launch pad on Thursday morning. "The baby has been delivered, and it's unfolded its solar arrays". The IRNSS-1I is expected to replace IRNSS-1A that was the first of the seven satellite constellation. With a lift-off mass of 1425 kg like all of its predecessors, it carries an L5 and S-band navigation payload with Rubidium Atomic Clocks on board. These clocks had been made by a leading Swiss firm, Spectratime, which provides timekeeping devices to navigation satellites the world over, including China's Compass constellation.

This is an independent Indian Satellite-based positioning system for critical National applications.

Of the seven satellites in NAVIC, built to provide fast and efficient navigation in India, two were built as backups. The spacecraft's other two clocks failed over the next six months, leaving it unable to broadcast navigation data.

For the first time, the launch vehicle incorporated indigenous friction stir welding technology in propellant tank manufacture, which according to a statement by ISRO Chairman Dr. K Sivan, will "improve productivity and enhance payload capability of the vehicle".

IRNSS is meant to be used for both civilian and military purposes.

"Very soon, we are going to come to the community - to the people - to deliver this product, and this is going to continue forever", Sivan said.
