After stopping the launch of Geosynchronous Satellite Launch Vehicle, GSLV-F04, seconds before its planned lift off at 16:21 hours (IST), the scientists successfully launched the vehicle that placed the crucial INSAT-4CR into its orbit.
Sriharkota, Sep 2 : After stopping the launch of Geosynchronous Satellite Launch Vehicle, GSLV-F04, seconds before its planned lift off at 16:21 hours (IST), the scientists successfully launched the vehicle that placed the crucial INSAT-4CR into its orbit.
The GSLV-F04 lifted off from the Satish Dhawan Space Centre SHAR in Sriharikota at 1820 hours (IST), two hours after its planned schedule, which was halted due to a glitch developed in the launch parameter.
There were communication errors between the cryogenic engine and onboard computer that led to rescheduling of the launch.
The INSAT-4CR is similar to the INSAT-4C, which was lost following the unsuccessful launch of GSLV-FO2 in July 2006, and will be used for Direct-To-Home television service and video picture transmission.
In 2006, the launch of GSLV-FO2 failed due to a snag resulting out of sudden loss of thrust in one of the four liquid propellant strap-on motors that led to the vehicle straying away from its designated path. The vehicle was destroyed 56 seconds after lift-off.
The INSAT-4CR, placed into the geo-synchronous transfer orbit (GTO) is equipped with 12 high power Ku-band transponders, and weighs 2,130 kilograms. It will also serve users of Very Small Aperture Terminals (VSATs) or business communications.
The ISRO Satellite Centre, Bangalore, built INSAT-4CR within one year.
The 49-metre-high launch vehicle weighs 414 tonnes and the first of the three- stage vehicle consists of a core motor powered by solid propellants.
The second stage comes alive with liquid propellants and cryogenic fluids - liquid hydrogen and liquid oxygen - provide the thrust to the third uppermost stage.
ISRO's Master Control Facility (MCF) will track the satellite's movement from Hassan in Karnataka and guide the spacecraft to the allotted slot in the geo-stationary orbit by firing its motors.
