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]
Launch
The satellite was launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre, Sriharikota on board PSLV-C33 XL on 28 April 2016 at 12:50 PM IST.[1][4] The countdown of the launch had begun 51:30 hours before at 9:20 AM IST on 25 April 2016.[5]
After the launch of IRNSS-1G the Indian government named the IRNSS system as NAVIC (Navigation with Indian Constellation).[6]
