In the series of the constellation of Regional Navigation Satellite System, ISRO launched, IRNSS-1G on board PSLV-C33 on Thursday from the spaceport of Sriharikota in Andhra Pradesh.
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).
According to ISRO officials total cost of all the seven satellites was Rs 1,420 crore.
Soon after the Mission Readiness Review Committee and the Launch Authorisation Board gave its approval on Monday, the 51.30 hour countdown for the launch of IRNSS-1G began at 09.20 hours on Wednesday and was “progressing smoothly” for the launch scheduled for Thursday from the first launch pad at Sriharikota by 12.50pm.
