''I am extremely happy to state that the PSVL-C17 GSAT-12 mission is successful. The launch vehicle injected the satellite very precisely into the intended orbit,'' said ISRO chairman, K Radhakrishnan.

This was the workhorse PSLV's 18th successful mission in a row.

GSAT-12 was injected into an elliptical Transfer Orbit of 284 km perigee (closest point to Earth) and 21,000 km apogee (farthest point to Earth).

Subsequently, the onboard Liquid Apogee Motor will be fired to place the GSAT-12 into a circular orbit. This is a critical manoeuvre and will place the satellite in a geo-stationary orbit.
