It is yet another successful launch for the ISRO's workhorse PSLV. India's Polar Satellite Launch Vehicle (PSLV-C17) successfully launched GSAT-12 communication satellite today (July 15, 2011) from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch of PSLV-C17 was the eighteenth successive successful flight of PSLV out of total nineteen flights.

After a smooth countdown of 53 hours, the vehicle lifted-off from the Second Launch Pad at the opening of the launch window at 16:48 hrs (IST). After about 20 minutes of flight time, GSAT-12 was successfully injected into sub-Geosynchronous Transfer Orbit (sub-GTO) with a perigee of 284 km and an apogee of 21,020 km with an orbital inclination of 17.9 deg.
