SES 14 [Airbus Defence and Space]
SES 14 is a geostationary communications satellite operating in C- and Ku-bands across the Americas and the North Atlantic region, which uses electric propulsion for initial orbit raising and all on-orbit manoeuvres.
The new satellite will be built by Airbus Space and Defence, based on the Eurostar E3000EOR bus, is scheduled for launch in Q4 2017 and will operate at 47.5° West, where it will replace SES's satellite NSS-806 and add new capacity.
SES-14 is a hybrid satellite with C- and Ku-band wide beam coverage, as well as Ku- and Ka-band High Throughput Satellite (HTS) coverage across the Americas and the North Atlantic region. The satellite will fully rely on electric propulsion and will be equipped with an electric plasma propulsion system for orbit raising and in-orbit manoeuvres. The electric propulsion system delivers significant reduction in the weight of the satellite, enabling larger payloads to be carried. The new spacecraft will also feature a Digital Transparent Processor (DTP), increasing the payload flexibility to provide customized bandwidth solutions to SES's customers.
SES-14's Ku-band wide beams will bring augmented capacity to serve growing Direct-to-Home and Direct-to-Cable video neighborhoods in the Americas and support existing VSAT services in both bands. The multi-spot Ku- and Ka-band beams will bring additional, high throughput capacity and are ideal for traffic-intensive data applications such as mobile backhaul, maritime and aeronautical services.
SES-14 will host NASA's Explorer program's GOLD (Global-Scale Observations of the Limb and Disk) payload. The primary purpose of GOLD is to revolutionize the understanding of the space environment by filling the critical gap in knowledge of Sun-Earth connections. The hosted payload will transmit data of the Sun’s impact on the Earth’s thermosphere and ionosphere from Geostationary (GEO) orbit. Both of these layers of the Earth’s upper atmosphere are very sensitive to space weather events and space climate, with potential societal impacts. Uncertainties in the thermosphere are a primary source of uncertainty for operating satellites in low Earth orbit. Fluctuations in the ionosphere interfere with signals from communications and global positioning satellites.
