GSAT-12, a geosynchronous satellite to be launched by PSLV on Jul 15

GSAT-12 ISRO's Communication Satellite, a geosynchronous satellite to be launched by PSLV.The launch date has been finalized on July 15, 2011, around 16:48 and 17:08 hrs IST.

We will soon post some warming up stuff on our education blog
which you can go through before the launch and enjoy the launch video ( generally available LIVE on Doordarshan TV channel ) armed with this background information.

Indian Space Research Organization’s engineers are busy getting the Polar Satellite Launch Vehicle (PSLV-C17) ready at Satish Dhawan Space Centre, Sriharikota. The PSLV-C17 will carry GSAT-12 – India’s communications satellite. The GSAT-12 satellite is special in its own way. It weighs 1410 kg at lift-off and features 12 Extended C-band transponders.

PSLV-C17′s mission is to launch the GSAT-12 in to the elliptical Transfer Orbit (Sub-GTO) of 284 km perigee and 21,000 km apogee. The satellite’s Liquid Apogee Motor will raise both apogee and perigee and put the satellite in the circular orbit of 36k km. All the four stages of the PSLV have been finalized and fully assembled at the Sriharikota center. The whole assembly is now being thoroughly tested and electrical check out is being carried out to avoid last minute schedule changes.

GSAT-12 has already been put through inspection by ISRO engineers. The filling of propellants began on June 28, 2011. The satellite and launch vehicles will be assembled starting July 03 only after green signal by the Launch Authorization Board. After the assembly, the whole setup will be moved to the second launch pad on July 10. The 52.5 hour countdown for the actual launch will begin on July 13. The actual launch time is expected to be around 16:48 and 17:08 hrs IST.
