GSAT-14 is an ISRO communication and experiment satellite. GSLV-D5 launched it in January 2014, with ISRO's own cryogenic engine powering the rocket's third stage.
GSAT-14 adds six extended C-band and six Ku-band transponders to India's satellite capacity. It replaced the education satellite GSAT-3 (EDUSAT). Two Ka-band beacons, at 20.2 and 30.5 GHz, let scientists study how rain and the atmosphere weaken Ka-band signals over India.
The satellite tested new hardware in orbit: a fibre-optic gyro, an active pixel Sun sensor and thermal control coatings. It weighed 1,982 kg at lift-off, makes 2,600 W of power and was designed for a 12-year life. It sits in geostationary-orbit at 74° East.
GSLV-D5 launched GSAT-14 from the Second Launch Pad at Sriharikota on 5 January 2014. It was the eighth GSLV flight and the fourth developmental one. Its third stage was the indigenous cryogenic upper stage, which burns liquid hydrogen and liquid oxygen and was built to replace the stage India had bought from Russia.
The public satellite catalogue carries GSAT-14 with an operational flag.
