GSAT-11 is an Indian communication satellite which is proposed to be launched by GSLV-MkIII, an indigenously developed spacecraft propelled by cryogenic engine. The satellite is aimed at providing advanced telecom and DTH services in the country.[3] GSAT-11 can transmit data at a speed of 10 Gigabytes per second to the entire nation.[4]


GSAT-11 will be developed at the cost of Rs. 500 crore. At 4.5 tonnes, it will weigh more than twice as much as the biggest Indian satellite in orbit now. With 16 high capacity multi-beams in Ku/Ka band, GSAT-11 will provide much faster uplinks for a host of communications and broadcasting services, including direct-to-home (DTH television). With a dry mass of 2.1 tonne, the spacecraft will provide 10 GHz of bandwidth, which will be equivalent to about 220 transponders of 36 MHz. The advanced satellite will employ a new I-4K satellite bus. It will be configured with two-sided large solar array panels generating 11 KW of power.[5]


The payloads will consists of 40 high power Ku, Ka band transponders that will be built at Space Applications Centre in Ahmedabad. The payloads will cover the entire country including Andaman and Nicobar Islands.[6]


The satellite is planned to be launched by 2016-17.[1]
