BANGALORE (PTI): Preparations are in full swing for the July 15 launch of the Polar Satellite Launch Vehicle (PSLV-C17) carrying India's communication satellite GSAT-12.

GSAT-12 with a mass of 1410 kg at lift-off, has 12 Extended C-band transponders, the Indian Space Research Organisation (ISRO) said in a statement.

PSLV-C17 would inject GSAT-12 into an elliptical Transfer Orbit of 284 km perigee (closest point to Earth) and 21,000 km apogee (farthest point to Earth).

Subsequently, the Liquid Apogee Motor of the satellite would 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 the Satish Dhawan Space Centre in Shriharikota.

Presently, the vehicle is going through various levels of electrical checkout operations and reviews", the Bangalore-headquartered ISRO said.

GSAT-12 has already undergone necessary testing at Shriharikota before commencing 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 GSAT-12 on board) is planned to be moved from the Building to the Second Launch Pad.

On July 13, the 52.5 hour countdown for the launch is expected to commence after launch rehearsals, clearance from Mission Readiness Review Teams and the Board.

The lift-off of PSLV-C17 from the second launch pad is scheduled on July 15 between 1648 and 1708 hrs.
