Bengaluru, June 29: Today early morning, Indian Space Research Organization ISRO successfully launched India’s communication satellite GSAT-17 from the spaceport of Kourou in French Guiana. Communication satellite GSAT-17 was successfully launched by a heavy duty rocket of Arianespace.

The European launcher Arianespace Flight VA238 blasted off from Ariane Launch Complex No 3 (ELA 3) at Kourou, a French territory located in northeastern coast of South America, couple of minutes delayed than the scheduled time of 2:29 hrs IST. GSAT-17 was injected shortly after orbiting co-passenger Hellas Sat 3-Inmarsat S EAN in a flawless flight lasting about 41 minutes. “GSAT-17 successfully launched by Ariane-5 VA-238 from Kourou, French Guiana.” 

The satellite has been inducted into the Indian National Satellite (INSAT)/GSAT system. It carried payloads in the normal C, extended C and S bands, providing various communication services. GSAT-17 also had equipment for meteorological data relay and satellite-based search and rescue services being provided by earlier INSAT satellites. 

"The satellite is designed to provide continuity of services of operational satellites in C, extended C, and S bands, and will be launched into a Geosynchronous Transfer Orbit (GTO)," Isro said. 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, noting it 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.” 

Appreciating this succesfully launched GSAT-17 satellite mission, manypeople and leaders congratulated ISRO on Twitter.

The total payload carried on Flight VA238 is approximately around 10,177 kg, with the mission lasting 39 minutes from liftoff to deployment of the two spacecraft passengers. Hellas Sat 3-Inmarsat S EAN is positioned as the upper passenger on Ariane 5, and will be released first during the flight, followed by GSAT-17’s deployment from the launcher’s lower payload position. Hellas Sat 3-Inmarsat S EAN is a two-payload “condosat” produced by Thales Alenia Space for Hellas Sat and Inmarsat. 

The satellite GSAT-17 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. 

Once in orbit, the Hellas Sat 3 components delivers DTH and telecom services to maintain and expand Hellas Sat’s business reach; while the Inmarsat S EAN component provides the satellite portion of Inmarsat’s new European Aviation Network. Built using the Thales Alenia Space Spacebus 4000C4 platform, Hellas Sat 3-Inmarsat S EAN has a liftoff mass of 5,780 kg.
