India's 2,170kg INSAT-4C is set to launch on July 10 from the Sriharikota space centre in Andhra Pradesh on board an India-built Geo-Synchronous Satellite Launch Vehicle (GSLV).
It will be the largest satellite ever to be launched from an Indian launcher and the first from the new second launch pad at Sriharikota. ISRO, the Indian Space Research Organisation is planning to launch a 4,000kg satellite in 2008.
According to The Times of India: "This type of rocket could in future be the vehicle of choice for launching manned space missions. Meanwhile, ISRO's current thrust is also to build shuttle type reusable launch vehicles that would lift off like rockets in order to insert satellites into orbit and then return by landing on runways like conventional aircraft."
INSAT-4C is the second of seven series 4 satellites to be launched. The 3,080 kg INSAT-4A was launched from an Ariane rocket last December and INSAT-$B will also be launched by Ariane. India claims the it is able to reduced launch costs by around 40 percent by using its own launcher.
INSAT-4C is an exclusive Ku-band satellite with 12 high power Ku-band transponders providing India coverage primarily for direct-to-home TV broadcasting. It has a design life of 10 years.
INSAT now has eight satellites in operation: INSAT-2E, INSAT-3A, INSAT-3B, INSAT-3C, INSAT-3E, KALPANA-1, GSAT-2 and EDUSAT. The organisation claims that, by 2007 it will have about 225 active transponders in various frequency bands by 2007.
The Indian National Satellite (INSAT) system is a joint venture of the Department of Space (DOS), Department of Telecommunications (DOT), India Meteorological Department (IMD), All India Radio (AIR) and Doordarshan. Founded in 1983, it is now one of the largest domestic communication satellite systems in the Asia Pacific Region.
