The 3164 kg GSAT-15 carries communication transponders in Ku-band and a GPS Aided GEO Augmented Navigation (GAGAN) payload operating in L1 and L5 bands.
"After a smooth countdown lasting 11 hours and 30 minutes, the Ariane 5 launch vehicle lifted off right on schedule at 3.04am (IST) on Wednesday," Isro said in a press note.
After a flight of 43 minutes and 24 seconds, GSAT-15 separated from the Ariane 5 upper stage in an elliptical Geosynchronous Transfer Orbit (GTO) with a perigee (nearest point to Earth) of 250 km and an apogee (farthest point to Earth) of 35,819 km, inclined at an angle of 3.9 degree to the equator. The achieved orbit was very close to the intended one.
ISRO's Master Control Facility (MCF) at Hassan in Karnataka has taken over the command and control and the preliminary health checks of the satellite revealed its normal health.
In the coming days, orbit raising manoeuvres will be performed to place the satellite in the Geostationary Orbit (36,000 km above the equator) by using the satellite's propulsion system in steps.
