'''GSAT-14''' is an [[India]]n [[communications satellite]] launched in January 2014. It replaced the [[GSAT-3]] satellite, which was launched in 2004. GSAT-14 was launched<ref>{{cite news|url=http://timesofindia.indiatimes.com/india/ISRO-successfully-launches-indigenous-cryogenic-engine-powered-GSLV-D5/articleshow/28437867.cms |title=ISRO successfully launches indigenous cryogenic engine-powered GSLV-D5 |work=[[The Times of India]]|date=5 January 2014 |access-date=7 February 2014}}</ref> by a [[Geosynchronous Satellite Launch Vehicle|Geosynchronous Satellite Launch Vehicle Mk.II]], which incorporated an Indian-built cryogenic engine on the third stage.

==Satellite==
GSAT-14 is part of the [[GSAT]] series of satellites. Constructed by [[Indian Space Research Organisation|ISRO]], it is based around the I-2K [[satellite bus]], and has a dry mass of {{convert|851|kg}}. With fuel, its mass is {{convert|1982|kg}}. The spacecraft has a design life of 12 years.<ref name="brochure">{{cite web|url=http://www.isro.gov.in/gslv-d5/pdf/brochure.pdf|title=GSLV-D5 Brochure|publisher=ISRO|access-date=19 August 2013|archive-url=https://web.archive.org/web/20140101052021/http://www.isro.gov.in/gslv-d5/pdf/brochure.pdf|archive-date=1 January 2014|url-status=dead}}</ref>

The satellite carries six [[Ku-band]] and six Extended [[C band (IEEE)|C-band]] [[transponder]]s to provide coverage of the whole of India. The satellite is expected to provide enhanced broadcasting services over the GSAT-3 satellite.<ref>{{cite web | url=http://www.thehindu.com/sci-tech/science/gslv-to-launch-gsat14-during-mid2012/article2113608.ece | title=GSLV to launch GSAT–14 during mid-2012 | work=The Hindu| date=18 June 2011 | access-date=20 March 2013}}</ref> GSAT-14 also carries two [[Ka-band]] beacons which will be used to conduct research into how weather affects Ka-band satellite communications. Fibre optic gyro, active pixel sun sensor, round type bolometer and field programmable gate array based earth sensors and thermal control coating experiments are new technologies which were flown as experiments in the satellite.<ref>{{cite web|url=http://space.skyrocket.de/doc_sdat/gsat-14.htm|title=Statistics}}</ref> The satellite is powered by two [[solar array]]s, generating 2,600 watts of power.<ref name="brochure"/>

The satellite was launched from the [[Satish Dhawan Space Centre Second Launch Pad|Second Launch Pad]] of the [[Satish Dhawan Space Centre]], atop a [[Geosynchronous Satellite Launch Vehicle|Geosynchronous Satellite Launch Vehicle Mk.II]] (GSLV Mk.II) rocket at 10:48 UTC (16:18 local time) on 5 January 2014.<ref name="LaunchSuccess">{{cite web | url=http://www.isro.gov.in/gslv-d5/mission.aspx | title=GSLV-D5 with Indigenous Cryogenic Stage successfully launches GSAT-14 from SDSC SHAR, Sriharikota on 5 January 2014 | publisher=ISRO | date=5 January 2014 | access-date=5 January 2014 | url-status=dead | archive-url=https://web.archive.org/web/20140104230506/http://www.isro.gov.in/gslv-d5/mission.aspx | archive-date=4 January 2014}}</ref> The 29-hour countdown began on 4 January 2014.<ref name="crazyengineers">{{cite web | url=http://www.crazyengineers.com/threads/isros-gslv-d5-is-ready-to-put-gsat-14-into-orbit.72429/ | title=GSLV-D5 is ready to put GSAT-14 into orbit | publisher=Crazy Engineers | date=30 December 2013 | access-date=31 December 2013}}</ref>

The flight marked India's forty-first satellite launch, the eighth launch of a GSLV, and the second flight of the Mk.II variant, whose maiden flight with [[GSAT-4]] had failed in 2010. It ended a run of four consecutive GSLV launch failures which began with [[INSAT-4C]] in 2006.<ref>{{cite web|url=http://www.nasaspaceflight.com/2013/08/indian-gslv-launch-gsat-14-communications-satellite/|title=Indian GSLV set to launch GSAT-14 communications satellite|publisher=NASASpaceflight.com|first=William|last=Graham|date=19 August 2013|access-date=19 August 2013|archive-url=https://web.archive.org/web/20130822012051/http://www.nasaspaceflight.com/2013/08/indian-gslv-launch-gsat-14-communications-satellite/|archive-date=22 August 2013|url-status=dead}}</ref> The launch marked the first successful flight test of the [[CE-7.5]], India's first cryogenically-fuelled rocket engine.
