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.
The 12 communication transponders onboard GSAT-14 will further augment the capacity in the INSAT/GSAT system.
ISRO's Cryogenic Upper Stage Project envisaged the design and development of the indigenous Cryogenic Upper Stage to replace the stage procured from Russia and used in GSLV flights, according to ISRO.
ISRO officials had been extremely vigilant in tightening loose ends this time around to avoid an unsuccessful attempt.
Design modifications were implemented wherever required in the launch vehicle along with thorough ground testing and improvements.
The modifications included redesigning of Lower Shroud, which protects the cryogenic engine during atmospheric flight of GSLV-D5 and redesigning of the wire tunnel of the cryo stage to withstand larger forces in flight.
The national space agency also performed two 'Acceptance Tests for flight unit of Fuel Booster Turbo Pump (FBTP), High altitude tests to confirm the ignition sequence in flight under vacuum, to validate design improvements and Cryogenic Main Engine (200 sec) and Steering Engine (100 sec) acceptance tests at Main Engine Test and High Altitude Test.
