GSAT-18 is a communication satellite of India built and developed by ISRO and operated by INSAT. It is a high power satellite being inducted into INSAT/GSAT system.
India’s latest communication satellite GSAT-18 was launched on 6th October 2016 from Kourou, French Guiana by Ariane-5 VA-231 into a Geosynchronous Transfer Orbit (GTO). It is the 20th ISRO the satellite launched by Arianespace.
o
With a
lift-off mass of 3404 kg, GSAT-18 carries 48 communication transponders to
provide services in normal C-band, Upper Extended C-band and Ku-bands of the
frequency spectrum.
o
It is
designed to provide continuity of services on operational satellites in C-band,
Extended C-band Ku-bands.
o GSAT-18 positioned at 74° East longitude and co-located with other operational satellites. The designed in-orbit operational life of GSAT-18 is about 15 years.
