'''GSAT-20''' is a communication satellite jointly being developed by [[Indian Space Research Organisation Satellite Centre]] and [[Liquid Propulsion Systems Centre]]<ref name="thehindu">{{Cite news |url=http://www.thehindu.com/sci-tech/science/gsat-9-heralds-cost-saving-electric-propulsion/article18347912.ece |title=GSAT-9 heralds cost-saving electric propulsion |last=D.S |first=Madhumathi |work=The Hindu |access-date=May 27, 2017 |agency=The Hindu |location=Bengaluru |publication-date=May 1, 2017}}</ref> and will be launched by [[ISRO]]. GSAT-20 will be a continuation of GSAT series of communication satellites. The satellite is intended to add data transmission capacity to the communication infrastructure required by [[Smart Cities Mission]] of India.

It will be the first fully Electric Propulsion/EP enabled satellite which can be five to six times more efficient than chemical-based propulsion.<ref name="thehindu"/> It will be the first ISRO made satellite to move from [[Geostationary transfer orbit]] to [[Geosynchronous orbit]] using Electric Propulsion.<ref name="thewire">{{Cite news |url=https://thewire.in/151354/grasp-isro-mk3-radiation-gsat-20/ |title=ISRO’s Mk III Launched a Little-Known Instrument Called GRASP – This Is What It Does |last=RAMACHANDRAN |first=R. |work=The Wire |access-date=June 26, 2017 |agency=The Wire |location=Bengaluru |publication-date=June 26, 2017}}</ref>
