IRNSS-1G was the seventh and final[1] of the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D, IRNSS-1E and IRNSS-1F. This system of satellites will provide navigational services to the Indian region. The satellite was launched successfully on 28 April 2016 at 07:20 UTC.[1]

IRNSS-1G along IRNSS-1A is being used only for NavIC's short message broadcast service and not for navigation.[2][3]
