Template:Short description Script error: No such module "about". Script error: No such module "Distinguish". Template:Infobox spacecraft class The GSAT (Geosynchronous Satellite)[1] satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting. As of 5 December 2018, 20 GSAT satellites manufactured by the Indian Space Research Organisation have been launched, out of which 14 are in service.

History

The GSAT series of geosynchronous satellites is a system developed by the Indian Space Research Organisation (ISRO) with an objective to make India self-reliant in broadcasting services. The system includes a total of 168 transponders (out of which 95 are leased out to provide services to broadcasters) in the C, Extended C and Ku bands, providing services to telecommunications, television broadcasting, weather forecasting, disaster warning and search and rescue operations.
