India will move closer to having its own navigation satellite system when the seventh and last in the series of the constellation of Regional Navigation Satellite System, IRNSS-1G on board PSLV-C33, will be launched from the spaceport of Sriharikota in Andhra Pradesh on Thursday.
The Indian Regional Navigation Satellite System, comprising seven satellites, would be able to provide navigation system with much better accuracy and targeted position.
While four satellites would be sufficient to start operations of the IRNSS system, the remaining three would make it "more accurate and efficient".
ISRO had launched the sixth navigation satellite IRNSS-1F on March 10, the other five being IRNSS-1A on July 1, 2013, IRNSS-1B (April 4, 2014), IRNSS-1C (October 16, 2014), IRNSS-1D (March 28, 2015) and IRNSS-1E (January 20, 2016).
