Preparations for the launch of Polar Satellite Launch Vehicle (PSLV-C17) targeted for July 15, carrying India's communication satellite GSAT-12 are progressing at Satish Dhawan Space Centre, Sriharikota, says ISRO.

GSAT-12 Communication satellite with a mass of 1410 kg at lift-off, has 12  Extended  C-band transponders. PSLV-C17 will inject GSAT-12 into an  elliptical Transfer Orbit (Sub-GTO) of 284 km perigee and 21,000 km apogee. Subsequently, the Liquid Apogee Motor of the satellite will be  used to raise both apogee and perigee of the Satellite to place it in a  circular orbit of 36,000 km altitude.

All the four stages of the launch vehicle have been fully assembled at the  Vehicle Assembly Building at Shriharikota. Presently, the vehicle is going  through various levels of electrical checkout operations and reviews.

GSAT-12 satellite has already undergone necessary testing at Shriharikota  before commencing the filling of propellants in the Satellite on June 28. On July 3, GSAT-12 Satellite is planned to be integrated with
PSLV-C17 vehicle at the Vehicle Assembly Building, after clearance by the Launch Authorisation Board.

On July 10,  PSLV-C17 Vehicle (with the GSAT-12 Satellite onboard) is  planned to be moved from the Vehicle Assembly Building to the Second  Launch Pad.

The lift-off of PSLV-C17 from the Second Launch Pad is scheduled on July 15 between 1648 and 1708 hrs.
