GSAT-11 is a large planned Indian geostationary communications satellite.

The 5725 kg satellite is based on the new I-6K Bus and carry 40 transponders in the Ku-band and Ka-band frequencies (32 Ka × Ku-Band Forward Link Transponders and 8 Ku × Ka band Return Link Transponders), which are 3-6 times more powerful than that used in existing Indian communications satellites and capable of providing up to 14 Gbit/s throughput.

The satellite was originally baselined to be launched by a GSLV Mk.3 rocket, but will now be put into orbit on a commercially procured Ariane launch.


GSAT-11 will be developed at the cost of Rs. 500 crore. At 5.7 tonnes, 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-6K satellite bus. It will be configured with two-sided large solar array panels generating 11 KW of power.[3]


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.[4]


The satellite is planned to be launched on June 2018.[1]
