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]

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.^[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 (Navigation with Indian Constellation).^[7]

Specifications

Mission life: 12 years (planned).^[6]

Lift-off mass:1,425 kilograms (3,142 lb)

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$13 million).^[13]
