'''GSAT-12''' is communication satellite designed and developed by the [[Indian Space Research Organisation]]. It is the second satellite to be launched and placed on a [[Geostationary transfer orbit|GTO]] using [[PSLV]].<ref name="gsat-gunter">{{cite web|url=https://space.skyrocket.de/doc_sdat/gsat-12.htm|title=GSAT-12/12R|publisher=Gunter Space Page|access-date=6 October 2020}}</ref><br />
<br />
==Satellite==<br />
GSAT-12 is considered to be a replacement of the aged satellite [[INSAT-3B]]. It will provide services like tele-education, tele-medicine, disaster management support and satellite internet access.<ref>{{cite web | url=http://www.thehindu.com/news/national/gsat12-reaches-its-home-in-a-circular-geosynchronous-orbit/article2260309.ece | title=GSAT-12 reaches its home in a circular geo-synchronous orbit | publisher=The HIndu | date=Jul 15, 2011| access-date=March 20, 2013}}</ref><br />
<br />
==Payloads==<br />
GSAT-12 is equipped with 12 Extended C-band transponders.<br />
<br />
==Launch==<br />
GSAT-12 was launched onboard [[Polar Satellite Launch Vehicle|PSLV-XL]] C-17 from [[Satish Dhawan Space Centre Second Launch Pad|second launch pad]] of [[Satish Dhawan Space Centre]] on July 15, 2011.<ref>{{cite web | url=http://articles.economictimes.indiatimes.com/2011-07-15/news/29777953_1_gsat-5p-communication-satellite-gsat12 | title=ISRO successfully launches latest communication satellite GSAT-12 | publisher=Economic Times | date=Jul 15, 2011 | access-date=March 20, 2013}}</ref> The tentative life of satellite is 8 years.<ref>{{cite web|url=http://space.skyrocket.de/doc_sdat/gsat-12.htm|title=GSAT-12|publisher=space.skyrocket.de}}</ref><ref>{{cite web|url=http://engineersworldonline.com/GSAT-12.html|title=GSAT-12 powered by PSLV is ready to launch|publisher=engineersworldonline.com}}</ref><br />
==Mission Life and Replacement==<br />
GSAT-12 has exceeded its planned mission life and continues to operate. A replacement satellite [[CMS-01]]''(formerly GSAT-12R)'' was launched on 17 December 2020.<ref name="gsat12r">{{cite web|url=https://www.tribuneindia.com/news/schools/isro-gearing-up-for-rocket-launches-with-virtual-launch-control-centre-151412|title=ISRO gearing up for rocket launches with Virtual Launch Control Centre|work=The Tribune|date=5 October 2020}}</ref><br />
<br />
== Relocation ==<br />
GSAT-12 has been relocated from 83°E slot.to 48°E slot on 19 March 2021.<ref>{{Cite web|title=Historical satellite position data for GSAT-12 for the month of March 2021|url=https://www.satellite-calculations.com/Satellite/getpositionhistory.php?37746?archive/2021/March/2021_March_|url-status=live|archive-url=https://web.archive.org/web/20210321204701/https://www.satellite-calculations.com/Satellite/getpositionhistory.php?37746?archive/2021/March/2021_March_|archive-date=2021-03-21|access-date=2021-03-21|website=www.satellite-calculations.com}}</ref><br />
