GSAT-14 is an Indian communications satellite which is scheduled to be launched in 2014. It is expected to replace the GSAT-3 satellite, which was launched in 2004. GSAT-14 will be launched by a Geosynchronous Satellite Launch Vehicle Mk.II, incorporating an Indian-built cryogenic engine on the third stage.
GSAT-14 is part of the GSAT series of satellites. Constructed by ISRO, it is based around the I-2K satellite 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.
The satellite carries six Ku-band and six Extended C-band transponders to provide coverage of the whole of India. The satellite is expected to provide enhanced broadcasting services over the GSAT-3 satellite. GSAT-14 also carries two Ka-band beacons which will be used to conduct research into how weather affects Ka-band satellite communications. The satellite is powered by two solar arrays, generating 2,600 watts of power.
The satellite is planned to be launched from the Second Launch Pad of the Satish Dhawan Space Centre, atop a Geosynchronous Satellite Launch Vehicle Mk.II (GSLV Mk.II) rocket. A launch attempt on 19 August 2013, with a planned liftoff at 11:20 UTC (4:50 pm local time), was scrubbed following a reported second stage fuel leak. A launch date of 15 December 2013 has been announced, but launch was postponed later until 2014.
While the probe for the failure to launch is in progress, ISRO has decided to replace the liquid second stage (GS-2) with a new one. Assembly of the new stage has already commenced. Additionally all the four liquid strap-on stages will replaced with new ones. ISRO also said it will replace the first stage and core base shroud if any affected elements are found on inspection.
“The satellite assembly, avionics equipment bay and the cryogenic stage will be preserved, following prescribed practices,
The flight will mark India's fortieth satellite launch, the eighth launch of a GSLV, and the second flight of the Mk.II variant. Following the failure of the previous Mk.II launch, with GSAT-5P, ISRO hopes that GSLV D5 will be the first successful launch with the Indian Cryogenic Engine, ending a run of four consecutive unsuccessful GSLV launches.
