At 20:31 on September 20, 2004, GM India, a GSLV geostationary satellite launch vehicle with a weight of 414 tons and a height of 49 meters, took off from the Sriharikota Space Center in southern India and took the Indian The first Eolusat satellite dedicated to education is in space. Seventeen minutes after the launch of the rocket, the satellite was successfully sent to a geostationary transfer orbit (GTO) 180 kilometers apogee, 35,985 kilometers apogee and 19.2 ° dip. This is the third launch of a GSLV rocket developed by India and the first launch of a practical synchronous satellite. Earlier, in April 2001 and May 2003, the rocket successfully launched two experimental communication satellites, G-Sat1 and G-Sat2. Edusat satellite by Indian Space Research Organization
