Sriharikota: Indian Space Research Organisation (ISRO) Geosynchronous Satellite Launch Vehicle (GSLV-F11) today successfully launched the latest communication satellite GSAT-7A from the Satish Dhawan Space Centre (SDSC) in Sriharikota.
The GSLV-F11 lifted off from the Second Launch Pad at SDSC at 04:10 pm IST, carrying 2,250 kg GSAT-7A and about 19 minutes later, injected GSAT-7A into a Geosynchronous Transfer Orbit (GTO) of 170.8 km x 39,127 km which is very close to the intended orbit.
Soon after the separation of the satellite, ISRO’s Master Control Facility (MCF) at Hassan in Karnataka took over the command and control of GSAT-7A. The satellite’s health parameters are normal. In the next few days, scientists at MCF will perform various orbit-raising manoeuvres, using GSAT-7A’s onboard propulsion system, to place the satellite in its final geostationary orbit.
Dr K Sivan, Chairman, ISRO said, “The team has achieved another spectacular milestone by launching GSAT-7A. In the last 35 days, ISRO has successfully launched three missions from SDSC starting with GSLV MkIII-D2 on November 14, PSLV-C43 on November 29 and finally GSLV-F11 today. GSLV has successfully injected GSAT-7A into a super-synchronous transfer orbit. GSAT-7A is the heaviest satellite being launched by GSLV with an indigenously developed cryogenic stage. The cryogenic stage of this vehicle has been modified to increase the thrust rate. GSAT-7A is an advanced communication satellite with a Gregorian Antenna and many other new technologies. The testing and realisation of this satellite have been carried out meticulously by ISRO team. We have signed off the year 2018 on a high and positive note.”
GSAT-7A is the 39th Indian communication satellite of ISRO to provide services to the users in Ku-band over the Indian region. Most of the functional requirements of the communication payloads and the other systems have been derived from ISRO’s earlier geostationary INSAT/GSAT satellites.
Mohan M, Mission Director and Killedar Pankaj Damodar, Satellite Director oversaw the launch proceedings.
