Next Ariane 5 mission set to launch Intelsat 37e and BSAT-4a satellites

Tuesday 5 September 2017, Ariane 5 will lift off from the Guiana Space Centre (CSG), Europe’s spaceport in Kourou, to place two telecommunications satellites into orbit: Intelsat 37e, built by Boeing for Intelsat, and BSAT-4a, built by Space Systems Loral (SSL) for the Broadcasting Satellite System Corporation (B-SAT). It will be the eighth launch of the year from the CSG, and the fifth launch of the year for Ariane 5, thereby bringing its total number of launches to 95.

With a launch mass of 6,438 kilograms, the Boeing-built Intelsat 37e satellite will provide the highest speed broadband of the entire Intelsat EpicNG fleet. It features enhanced power distribution technology for on-demand service optimization according to application and regional requirements. This will ensure improved transmission for mobile and institutional customers on the American, African and European continents. It has an expected service lifetime of more than 15 years.

With a launch mass of 3,520 kilograms and built by Space Systems loral, the BSAT-4a satellite will provide Direct-to-Home (DTH) digital television services across the entire Japanese archipelago. Its technology will make it possible to extend coverage of the most advanced broadcasting services, such as high definition and very high definition TV. It will cover the entire Japanese archipelago and has an expected service lifetime of 15 years.
