'''GSAT-30''' is a [[Engineering:Telecommunication|telecommunication]]s satellite developed by the [[Astronomy:Indian Space Research Organisation|Indian Space Research Organisation]] (ISRO).<ref name="VA251_LK"/><ref name="GSAT30_LK"/>

== Mission ==
The satellite's main communication payload is 12 [[Astronomy:Ku band|Ku]] band transponders for covering Indian mainland and islands and 12 [[Astronomy:C band (IEEE)|C-band]] [[Astronomy:Transponder (satellite communications)|transponders]] for extended coverage over [[Earth:Asia|Asia]] and Australia. The satellite will act as a replacement for the defunct [[Engineering:INSAT-4A|INSAT-4A]].<ref name="VA251_LK"/> The satellite provides advanced telecommunication services to the Indian subcontinent. It is used for [[Engineering:Very-small-aperture terminal|Very-small-aperture terminal]] (VSAT) networks, television uplinks, [[Engineering:Electronic news-gathering|digital satellite news gathering]], [[Engineering:Direct-broadcast satellite|Direct-broadcast satellite]] (DTH) services and other communication systems. This is the 41st communication satellite launched by ISRO and the 24th launch of ISRO satellite by [[Company:Arianespace|Arianespace]].<ref name="gsat30">{{cite web |url=https://www.arianespace.com/mission-update/va251-gsat-integration/|title=GSAT-30 is installed on Ariane 5 for Arianespace's first mission of 2020|publisher=Arianespace|access-date=9 January 2020}}</ref><ref name="GSAT30_LK"/><ref>{{cite web|url=https://thewire.in/space/isro-gsat-30-satellite-ariane-5|title=ISRO's GSAT-30 Satellite Successfully Launched Aboard Ariane Rocket|publisher=The Wire|access-date=2020-01-17}}</ref>
