GSAT-14 is an Indiancommunications satellite launched in January 2014. It replaced theGSAT-3 satellite, which was launched in 2004. GSAT-14 was launched[3] by aGeosynchronous Satellite Launch Vehicle Mk.II, which incorporated an Indian-built cryogenic engine on the third stage.
GSAT-14 is part of theGSAT series of satellites. Constructed byISRO, it is based around the I-2Ksatellite bus, and has a dry mass of 851 kilograms (1,876 lb). With fuel, its mass is 1,982 kilograms (4,370 lb). The spacecraft has a design life of 12 years.[4]
The satellite carries sixKu-band and six ExtendedC-bandtransponders to provide coverage of the whole of India. The satellite is expected to provide enhanced broadcasting services over the GSAT-3 satellite.[5] GSAT-14 also carries twoKa-band beacons which will be used to conduct research into how weather affects Ka-band satellite communications. Fibre optic gyro, active pixelSun 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.[6] The satellite is powered by twosolar arrays, generating 2,600 watts of power.[4]
A launch attempt on 19 August 2013, with a planned liftoff at 11:20 UTC (4:50 pmlocal time),[7][8] was scrubbed following a reported second stage fuel leak.[9][10] While the probe for the failure to launch was in progress, ISRO had decided to replace the liquid second stage (GS-2) with a new one.[11] In the process, all the four liquid strap-on stages were replaced with new ones.[11]
The satellite was launched from theSecond Launch Pad of theSatish Dhawan Space Centre, atop aGeosynchronous Satellite Launch Vehicle Mk.II (GSLV Mk.II) rocket at 10:48 UTC (16:18 local time) on 5 January 2014.[12] The 29-hour countdown began on 4 January 2014.[13]
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 withGSAT-4 had failed in 2010. It ended a run of four consecutive GSLV launch failures which began withINSAT-4C in 2006.[14] The launch marked the first successful flight test of theCE-7.5, India's first cryogenically fuelled rocket engine.
