Шаблон:About Шаблон:Infobox spacecraft class The GSAT (Geosynchronous Satellite) satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting. As of 5 December 2018, 20 GSAT satellites of ISRO have been launched out of which 14 satellites are in service.

History

The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services. The repertoire of 10 GSAT satellites, a total of 168 transponders (out of which 95 transponders are leased out to provide services to the broadcasters) in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, weather forecasting, disaster warning and search and rescue operations.
