Edusat is an Indian (ISRO) geostationary satellite that was launched by a GSLV (F04) rocket from Sriharikota (on the east coast) at 10:31 UT on 20 September 2004. It is the fourth launch of the GSLV rocket which carries a Russian made motor on its cryogenic third stage. The third and final apogee burn on 24 September moved the satellite from the transfer orbit to a geostationary orbit. The 2.0 tonne, 2.0 kW satellite will provide interactive educational programs to thousands of schools in different linguistic regions via five spot-beams from its five Ku-band transponders, and via wider beams from six Extended C-band transponders. It is now slowly drifting to its parking longitude of 74 deg-E.
