The four Ka-band O3b satellites will join the other O3b satellites already in Medium Earth Orbit (MEO) to provide low latency, fibre-like connectivity in the booming mobility, fixed data and government markets.



By expanding its O3b fleet, SES will be able to offer 38% more capacity worldwide, and extend its potential market from 45 to 50 degrees north and south latitude.



These new satellites will enable SES Networks to offer more capacity, extended coverage, greater efficiency and higher reliability. At the same time, they will provide operator-class services to businesses, government customers, telecommunications companies, mobile network operators and internet service providers.



Arianespace will launch four more O3b satellites into Medium Earth Orbit for this constellation in 2019.



Arianespace launches 57 satellites for SES in a 30-year partnership



SES, a world-leading satellite operator, is the first to deliver a differentiated and scalable GEO-MEO offering worldwide, with more than 50 satellites in geostationary Earth orbit (GEO) and 12 satellites in Medium Earth Orbit (MEO).



Arianespace and SES have developed an exceptional partnership over the last 30 years, made even stronger by this latest successful launch. Because of its versatile and complementary family of launchers, Arianespace is perfectly suited to address SES's GEO/MEO strategy and the requirements of its future programs.



The Arianespace family: especially well-suited to constellation launches



With its current family of launchers (Ariane 5, Soyuz and Vega) and its future family (Ariane 6 and Vega C), Arianespace enjoys an excellent position in the growth market of satellite constellations, whether for navigation, telecommunications or Earth observation; and for initial deployment, as well as subsequent replacement launches.
