Bangalore: 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 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.
