ISRO Successfully Launches IRNSS-1I Navigation Satellite From Sriharikota [WATCH]

A total of 14 days after ISRO's failed space attempt when its satellite was lost to a systems failure, the Indian Space Research Organisation (ISRO) successfully launched its Polar Satellite Launch Vehicle (PSLV) carrying IRNSS-1I satellite on Thursday morning from Andhra Pradesh's Sriharikota.

The launch of IRNSS-1I, the eighth satellite for India's indigenous global positioning system took place at 4:04 AM on Thursday, after the much larger Geosynchronous Satellite Launch Vehicle (GSLV) rocket launch on March 29, marking the fastest back-to-back launch in ISRO history.

Although the GSLV launch on March 29 had taken place successfully, the Rs. 270 crore GSAT 6A satellite it was carrying was confirmed to be lost due to systems failure on April 1.

The 43rd mission of the PSLV taking place on Thursday was declared a success by ISRO after the IRNSS-1I was placed into a precise orbit.

ISRO Chairman Dr K Sivan after the launch said, "I am extremely happy to announce that the 8th navigation satellite of India was launched successfully into the NAVIC constellation. We are moving towards a major goal. This NAVIC constellation will create history."

The NAVIC, an acronym for "Navigation with Indian Constellation" is the operational name for the Indian Regional Navigation Satellite System (IRNSS) which is designed to be equivalent to the Global Positioning System (GPS) owned by the US.

Currently, only the US and Russia have fully operational GPS systems, while China and Europe are still deploying their own full systems. A native satellite-based navigation system is considered to be a deep strategic asset, useful in civilian and military fields.

The need for an indigenous GPS in India was identified after the Kargil conflict when India desperately needed services of satellite-based navigation system but did not have one of its own.
