Next Ariane 5 mission set to launch Hellas Sat 3-Inmarsat S EAN and GSAT-17 satellites

Wednesday 28 June, Ariane 5 will lift off from the Guiana Space Centre (CSG), Europe’s spaceport in Kourou, to place two new telecommunications satellites into orbit: Hellas Sat 3-Inmarsat S EAN, built by Thales Alenia Space for Hellas Sat – Inmarsat, and GSAT-17, built by ISRO/ISAC for the Indian Space Research Organization (ISRO). This will be the seventh launch of the year from the CSG, Ariane 5’s fourth in 2017 and its 94th in total.

With a launch mass of de 5,780 kilograms, Hellas Sat 3-Inmarsat S EAN is a satellite built by Thales Alenia Space in Cannes. It will deliver in-orbit back-up direct-to-home (DTH) and telecom services, bringing video content in high definition and ultra-high definition to the covered regions and S-band in-flight connectivity for the European Avian Network (EAN), an integrated satellite and ground network designed to deliver reliable inflight broadband to airline passengers across Europe. The satellite will cover Europe, the Middle East and Sub-Saharan African countries. It has an expected service lifetime of more than 15 years.

With a launch mass of 3,551 kilograms, GSAT-17 is a satellite built by ISRO/ISAC. GSAT-17 will strengthen ISRO’s current fleet of 17 operational telecom satellites, providing continuity of fixed satellite services (FSS), mobile satellite services (MSS) and data relay and search-and-rescue services. It will cover India, the Middle East and Southeast Asia. It has an expected service lifetime of 15 years.
