IRNSS-1G was the seventh and final[2] 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.[2]
IRNSS-1G along IRNSS-1A is being used only for NavIC's short message broadcast service and not for navigation.[3] [4]
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 .[2] [5] The countdown of the launch had begun 51:30 hours before at 9:20 AM IST on 25 April 2016.[6]
After the launch of IRNSS-1G the Indian government named the IRNSS system as NAVIC (Nav igation with I ndian C onstellation).[7]

Dry mass: 598 kilograms (1,318 lb ).[8]
Payload: CDMA ranging payload in C band .[9] [10] Navigation payload in L-5 and S band spectrums and Rubidium atomic clocks .[11]
Power: Two triple-junction solar panels to generate 1660W of energy and one Lithium-ion 90A-hr battery is used.[8]
Propulsion: MMH /MON3 based bipropellant system with 12×22N Attitude control thrusters and one 440N LAM .[10]
Orbit: Geosynchronous orbit at 129.5° East longitude with 5° inclination.[8] [12]
Cost: Approximately ₹ 125 crore (US$15 million).[13]
