The count down has started for the launch of India's latest communication satellite GSAT-5P on board GSLV-F06 launch vehicle from Sriharikota on Friday.
ISRO spokesperson S Satish told PTI that the 30-hour count down started at 10.04 hours this morning and was progressing well.
The launch of the satellite, which was originally scheduled for December 20, had been postponed after a leak in the Russian cryogenic engine on board the launch vehicle.
GSAT-5P with 24 C-band transponders and 12 extended C-band transponders is meant for augmenting communication services currently provided by Indian National Satellite System (Insat). It is meant to boost TV, telemedicine and tele-education, and telephone services.
The satellite, developed by ISRO Satellite Centre, Bangalore, is the fifth in the GSAT series. It has a designed mission life of 12 years.
