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

The 5725 kg[citation needed] 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 capable of providing up to 14 Gbit/s throughput. The satellite was planned to be launched in May 2018[3], but was delayed after ISRO recalled it back to India from the launch site in French Guiana for additional checks weeks after ISRO lost communication to another communication satellite, the GSAT-6A, soon after its launch in March 2018.[4]

After the satellite was found fit for the launch, the new launch date has been set to 30 November 2018.[3][5] GSAT-11 will be launched from the European spaceport in French Guiana as ISRO's own Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) rocket can only lift a satellite weighing not more than four tonnes to Geostationary transfer orbit.[6]

Satellite[edit]

GSAT-11 will be developed at the cost of Rs. 500 crore.[7] The payloads will consists of 40 high power Ku, Ka band transponders that will be built at Space Applications Centre in Ahmedabad.[8]
