About the GSAT-18 launch
GSAT-18 is designed to provide continuity of services on operational satellites in C-band, Extended C-band and Ku-bands. It was launched into a Geosynchronous Transfer Orbit (GTO) by Ariane-5 VA-231 launch vehicle. After its injection into GTO, ISRO’s Master Control Facility (MCF) at Hassan took control of GSAT-18 and performed the initial orbit raising maneuvers using the Liquid Apogee Motor (LAM) of the satellite, placing it in circular Geostationary Orbit.
The designed in-orbit operational life of the satellite is about 15 years.
