GSAT-11
GSAT-11 is planned to be launched in which will provide advanced telecom services in India. With a weight of 4.5 tonnes, it will weigh more than twice as much as the biggest Indian satellite in orbit now. The advanced communications technology satellite will be launched in 2013 on board the Geo-Synchronus Satellite Launch Vehicle (GSLV-Mark III) from ISRO's spaceport at Sriharikota, about 80 km north-east of Chennai. The satellite will be designed at satellite centre in Bangalore, payloads consisting of 40 transponders in Ku/Ka band will be built at the space applications centre in Ahmedabad and the 630-tonne rocket (GSLV-Mark III) will be rolled out from the liquid propulsion systems centre in Thiruvananthapuram. 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 1-4K Bus (computer network). It will be configured with two-sided large solar array panels generating 11 KW of power. In the run-up to GSAT-11, the space agency is scheduling the launch of other communications satellites in the GSAT series by 2011-12.
