Configured around I-3K extended bus, the GSAT-17 carries payloads in Normal C- band, Extended C-band and S-band to provide various communication services. The satellite also carries equipment for meteorological data relay and satellite-based search and rescue services being provided earlier by INSAT satellites. Launched into a Geosynchronous Transfer Orbit (GTO), GSAT-17 will strengthen Isro’s current fleet of 17 telecommunications satellites. 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. GSAT-17 was the 21st satellite from Isro to be launched by Arianespace and its designed in-orbit operational life is about 15 years. 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.
GSAT-17 will be positioned at its designated orbital slot in the geostationary orbit and will be co-located with some of the Indian operational geostationary satellites. After the successful completion of all the in-orbit tests, GSAT-17 will be ready for operational use. GSAT-17’s co-passenger Hellas Sat 3-Inmarsat S EAN is a two-payload “condosat” produced by Thales Alenia Space for Hellas Sat and Inmarsat. Once in orbit, the Hellas Sat 3 component will deliver direct-to-home 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.
