Bengaluru, June 29 (PTI): India’s latest communication satellite GSAT-17 was today successfully launched by a heavy duty rocket of Arianespace from Kourou in French Guiana, adding teeth to its current fleet of 17 working communication satellites.
The GSAT series of geosynchronous satellites is a system developed by the Indian Space Research Organisation(ISRO) with an objective to make the country self-reliant in broadcasting services.
The 3,477-kg GSAT-17 was injected shortly after orbiting co-passenger Hellas Sat 3-Inmarsat S EAN in a flawless flight lasting about 39 minutes.
“GSAT-17 successfully launched by Ariane-5 VA-238 from Kourou, French Guiana,” the city-headquartered ISRO announced after the mission. The designed in-orbit operational life of GSAT-17 is about 15 years, it said.
ISRO’s Master Control Facility (MCF) at Hassan in Karnataka took over the command and control of GSAT-17 immediately after its separation from the launch vehicle, and the preliminary health checks of the satellite revealed its normal functioning.
Configured around I-3K extended bus, GSAT-17 with a lift-off mass of about 3,477 kg carries payloads in Normal C- band, Extended C-band and S-band to provide various communication services.
It also carries equipment for meteorological data relay and satellite based search and rescue services being provided by earlier INSAT satellites.
GSAT-17 that will strengthen ISRO s current fleet of 17 telecommunications satellites was launched into a Geosynchronous Transfer Orbit (GTO).
This was the third satellite launch mission by ISRO this month, the other two being first developmental flight of GSLV MkIII and PSLV C-38 missions--both from Sriharikota spaceport in Andhra Pradesh.
GSAT-17 is also ISRO’s third communication satellite to successfully reach orbit in the past two months.
ISRO, which has been dependent on Ariane-5 rocket for carrying its heavier satellites, is developing GSLV Mk III for this purpose.
Announcing the successful launch of the satellite, Arianespace CEO Stephane Israel tweeted: “Confirmed: GSAT-17 has successfully separated from its #Ariane5 launcher #VA238 @ISRO.”
Thanking Arianespace, Director, Vikram Sarabhai Space Centre Dr K Sivan, who watched the launch from the mission control centre called it a “text book mission”.
Describing the launch as a special mission for ISRO, he said, “GSAT-17 is a need of the hour for ISRO and India as it provides the continuity in services of ageing two satellites, as well as augmenting our transponder capability, and widening our horizon to mobile satellite services as well as to Antarctica areas.”
GSAT-17 was the 21st satellite from ISRO to be launched by Arianespace.
In the coming days, orbit raising manoeuvres will be performed to place GSAT-17 satellite in the Geostationary Orbit (36,000 km above the equator) by using the satellite s propulsion system in steps, the space agency has said.
During the final stages of its orbit raising operations, the two solar arrays and both the antenna reflectors of GSAT- 17 will be deployed and following this, the satellite will be put in its final orbital configuration.
