<p>The countdown for the Thursday launch of India's latest communication satellite GSAT-6 will begin tomorrow, Indian Space Research Organisation said today.<br /><br /></p>.<p>Mission Readiness Review (MRR) committee and Launch Authorisation Board (LAB) have cleared the starting of the 29- hr countdown at 1152 hrs, ISRO said.<br /><br />The launch of Geo-synchronous Satellite Launch Vehicle (GSLV) D6 carrying GSAT-6 is scheduled at 1652 hours on August 27 from Satish Dhawan Space Centre at the spaceport of Sriharikota in Andhra Pradesh.<br /><br />GSAT-6 is the 25th geostationary communication satellite of India built by ISRO and 12th in the GSAT series.<br /><br />GSAT-6 provides communication through five spot beams in S-band and a national beam in C-band for strategic users, ISRO said.<br /><br />The cuboid shaped GSAT-6 has a lift-off mass of 2117 kg. Of this, propellants weigh 1132 kg and the dry mass of the satellite is 985 kg, it added.<br /><br />One of the advanced features of GSAT-6 satellite is its S-Band Unfurlable Antenna of 6 m diameter. This is the largest satellite antenna realised by ISRO.<br /><br />This antenna is utilised for five spot beams over the Indian mainland. The spot beams exploit the frequency reuse scheme to increase frequency spectrum utilisation efficiency, ISRO said.<br /><br />ISRO said after satellite's injection into GTO (Geosynchronous Transfer Orbit) by GSLV-D6, ISRO's Master Control Facility (MCF) at Hassan takes control of GSAT-6 and performs the initial orbit raising manoeuvres by repeatedly firing the Liquid Apogee Motor (LAM) on board the satellite, finally placing it in the circular Geostationary Orbit.<br /><br />After this, deployment of the antenna and three axis stabilisation of the satellite will be performed. GSAT-6 will be positioned at 83 deg East longitudes, it added.<br />The mission life of the satellite is for nine years.</p>
