Hellas-Sat 3 is a powerful telecommunications condominium satellite for Inmarsat and Hellas-Sat. The satellite will provide Mobile Satellite Services (MSS), Fixed Satellite Services (FSS) and Broadcast Satellite Services (BSS). It is equipped with Ka/S-band payload, 47 Ku-band transponders, 1 Ka-band transponder. Weighing 5900 kg at launch, the satellite is to reside in geostationary orbit in an orbital position 39° East, where it is expected to operate for about 15 years. GSAT-17 is a communication satellite with a lift off mass of 3425 kg and 6 KW power generation capacity. The satellite's commercial transponders include Ku-band, Normal C-band and Extended C-band transponders. It additionally carries a dedicated transponder for data relay (DRT) and search-and-rescue (SAR) services.
