BANGALORE: Spacecraft checkout room No 1 at ISRO’s (Indian Space Research Organisation) Satellite Centre is a scene of hectic activity these days. Scientists are working round-the-clock, monitoring information about a huge satellite that is undergoing tests in a sterile chamber.

The satellite, having a 10-year life span, is the two-tonne INSAT-4C which is tentatively slated for launch during the middle of this year. A communication satellite, it will be placed in the geo-synchronous orbit, 36,000 km above the equator.

The rocket, which will carry the satellite, is the indigenous three-stage geo-synchronous satellite launch vehicle (GSLV). It will lift off from the Satish Dhawan Space Centre, Sriharikota.

The third stage of the vehicle which will inject the satellite into the geo-synchronous transfer orbit will operate at a speed of 7-10 km per second.

ISRO officials told TOI the final assembly of the satellite was in progress. “We are now fixing the propulsion system. Soon the complete satellite will be ready with the solar panels. After this we will initiate the ground tests,” an official said.
