"I am extremely happy and proud to say team ISRO has done it. The Indian cryogenic engine and stage performed as predicted, as expected for this mission and injected precisely the GSAT-14 communication satellite into intended orbit," a jubilant K Radhakrishnan, ISRO chairman, said from the Mission Control Room soon after the launch vehicle placed the 1,982 kg GSAT 14 satellite into the intended orbit. Launching a GSLV with an indigenous cryogenic engine has been a major challenge for ISRO since 2001 after multiple unsuccessful attempts. Only four of earlier seven attempts have succeeded.
GSLV D5's scheduled launch on August 19 last year was called off in the eleventh hour after a fuel leak, following which ISRO moved the vehicle back to the Vehicle Assembly Building and rectified the defect.
Today's launch is India's eighth flight of GSLV and also the fourth developmental flight of GSLV. During this flight, the indigenously developed Cryogenic Upper Stage (CUS) was flight tested for the second time.
GSAT-14 is India's 23rd geostationary communication satellite, as four of GSAT-14s predecessors were launched by GSLV during 2001, 2003, 2004 and 2007, respectively. GSAT-14 would join the group of India's nine operational
geostationary satellites. The primary objective of this mission is to augment the in-orbit capacity of extended C and Ku-band transponders and provide a platform for new experiments.
The GSAT-14 will be positioned at 74 degree East longitude and co-located with INSAT-3C, INSAT-4CR and KALPANA-1 satellites.
