Manufacturer:Indian Space Research Organization (ISRO)
Operator:Indian Space Research Organization (ISRO)
Launch operator:Arianespace
Launch vehicle:Ariane 5ECA
Launch date:10/06/2016
Expected lifetime:15+ Years

GSAT-18 was constructed by ISRO and added to the INSAT/GSAT-system in 2016. The designed in-orbit operational lifespan of GSAT-18 is about 15 years.

Weighing 3,404 kg at lift-off, GSAT-18 carries 48 communication transponders to provide Services in Normal C-band, Upper Extended C-band and Ku-bands of the frequency spectrum. GSAT-18 carries Ku-band beacon as well to help in an accurately pointing ground antennas towards the satellite.

GSAT-18 is designed to provide continuity of services on operational satellites in C-band, Extended C-band and Ku-bands. GSAT-18 was launched on October 6th, 2016 into a Geosynchronous Transfer Orbit (GTO) by Ariane-5 VA-231 launch vehicle, operated by launch operator Arianespace, from Kourou, French Guiana.

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.
