Today’s launch will complete the Space Segment – India’s regional navigation system compared to United States’ Global Positioning System (GPS) that provides location and time details accurately worldwide.
Earlier ISRO had launched IRNSS-1A, 1B, 1C, 1D, 1E and 1F in July 2013, April 2014, October 2014, March 2015, january 2016 and March 2016, respectively.
