GSAT-11 is ISRO's high-throughput communication satellite for broadband, using many narrow spot beams over India. At 5854 kg it was the heaviest satellite ISRO had built when it launched from French Guiana in December 2018.
GSAT-11 provides broadband services across India using multiple spot beams over the mainland and islands. ISRO described it as the forerunner of a series of advanced communication satellites.
Its payload has 40 transponders in the Ku and Ka bands: 32 for the forward link and 8 for the return link.
The satellite weighed about 5854 kg at launch. Its solar panels generate 13.6 kW, and ISRO planned a mission life of 15 years.
An Ariane-5 rocket (flight VA-246) launched GSAT-11 from Kourou, French Guiana, into a geosynchronous transfer orbit. ISRO's Master Control Facility at Hassan then fired the satellite's liquid apogee motor to reach circular geostationary orbit.
The public satellite catalogue carries GSAT-11 with an operational flag in geostationary orbit.
