As of 5 December 2018, 20 GSAT satellites manufactured by the [[ISRO|Indian Space Research Organisation]] have been launched, out of which 14 are in service.

== History ==
The GSAT series of [[Geosynchronous satellite|geosynchronous satellites]] is a system developed by the [[ISRO|Indian Space Research Organisation]] (ISRO) with an objective to make India self-reliant in broadcasting services. The system includes a total of 168 [[Transponder (satellite communications)|transponders]] (out of which 95 are leased out to provide services to broadcasters) in the [[C band (IEEE)|C]], Extended C and [[Ku band|K<sub>u</sub>]] bands, providing services to telecommunications, television broadcasting, weather forecasting, disaster warning and search and rescue operations.
