The 49 metre long rocket carrying 2,130 heavy satellite blasted off from Sriharikota island at 6:20 two hours late of the scheduled time due to the signal problem at the third cryogenic stage. As the rocket was just about to lift off the signal from the ground system failed to come some seconds ago.
INSAT-4CR replaced INSAT-4C which was destroyed last year in July after some technical failure. The satellite has 12 wideband channels or transponders significant in providing services in telecommunications, television broadcasting and meteorology. This is to be known that internet congestion has become common phenomenon due to increased traffic.
This was the fifth launch of Geosynchronous Satellite Launch Vehicle series rocket. In April ISRO also launched an Italian satellite for the first time charging fees for it stepping in commercial launch market. Till yet space technology has not been used commercially at extensive level barring few cases.
Amid the hopes for future and fears of the past the successful launch of the largest domestic communication satellite system of Asia, INSAT-4CR (INSAT series) by the GSLV FO4 on Sunday laid down the path for India to enter the arena of 2.5 billion dollar satellite launch business.
This successful launch not only opened the door of global satellite launch business but will also cater to the upward-moving domestic telecommunications demand. ISRO Chairman told that they are receiving enquiries from foreign customers.
ISRO chairman, G Madhavan Nair expressed a sigh of relief over Sunday's successful launch and said that Indian rockets are as reliable as any other launch vehicle in the world.
He termed the whole phenomenon as high drama. Prime Minister Manmohan Singh congratulated ISRO Chairman.
INSAT-4CR promises a boost to digital communications.
Promising a boost to digital communications in India, Indian Space Research Organization (ISRO) successfully launched its latest communications satellite, Insat-4CR yesterday.
Facing a series of delays caused by technical glitches, the Geosynchronous Satellite Launch Vehicle GSLV-F04 lifted off at 6.20 p.m. from Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, India.
Around 17 minutes after launch, and about 5,000 Km from the launch station, the vehicle placed India's INSAT-4CR into the Geosynchronous Transfer Orbit (GTO).
Though the fifth flight of the 49m tall GSLV, it was the fourth successful one. The second operational flight, GSLV-F02, with INSAT-4C on board, carried on July 10, 2006, did not succeed.
The third satellite in the INSAT-4 series, INSAT-4CR, weighs 2,130 Kg and has a lifespan of 10 years. Carrying 12 high-power Ku-band transponders, the communication satellite is expected to boost direct-to-home (DTH) television broadcasts, Video Picture Transmission (VPT) and Digital Satellite News Gathering (DSNG) in India.
INSAT-4CR is now orbiting the Earth in GTO with a perigee (nearest point to Earth) of 168 km and an apogee (farthest point to Earth) of 34,710 km with an orbital inclination of 20.7 degree with respect to the equator, ISRO officials revealed.
INSAT-4CR was developed by ISRO Satellite Centre, Bangalore with a cost of Rs. 150 crore, while, the GSLV was designed and developed by Vikram Sarabhai Space Centre, Thiruvananthapuram. The cost of the vehicle was Rs. 160 crore.
The satellite will be monitored by the ground station of the ISTRAC located in the Indonesian island of Biak. Further, the ground stations at Lake Cowichan (Canada), Fucino (Italy) and Beijing (China) along with the Master Control Facility (MCF) at Hassan in Karnataka will monitor the wellbeing of the satellite and its orbit raising operations.
In the days to come, INSAT-4CR's orbit will be raised from its present elliptical GTO to the final Geostationary Orbit (GSO) by firing the satellite's Liquid Apogee Motor (LAM) in stages. There, it will be co-located with KALPANA-1, INSAT-3C and EDUSAT.
