SES-14 Goes Operational to Serve the Americas

SES’s geostationary satellite with its wide-beam and high throughput capabilities will capture attractive growth opportunities in video, maritime and aeronautical markets across the Americas

Luxembourg, 4 September 2018 – SES announced today that the high-powered SES-14 satellite, positioned at 47.5 degrees West, is now serving Latin America, the Caribbean, North America, North Atlantic and West Africa.

The all-electric satellite, which has both C- and Ku-band wide-beam coverage and Ku-band high throughput spot beam coverage, is SES's second hybrid satellite to serve the Americas, with the first being SES-15. 

SES-14's C-band and Ku-band wide beams and high throughput capabilities are serving various markets. The satellite is expanding the reach of SES’s second cable neighbourhood in Latin America, and provides new capacity for direct-to-home services. It is also delivering more high-speed connectivity to the dynamic aeronautical market and other traffic-intensive applications in the maritime and cellular backhaul markets.

The satellite also carries a hosted payload for NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission. GOLD will provide unprecedented imaging of the Earth’s upper atmosphere from geostationary orbit to deepen scientists' understanding of the boundary between Earth and space.

SES-14 at 47.5 degrees West is replacing and augmenting services currently provided on NSS-806. The license to operate at this Brazilian orbital location was the result of SES’s successful participation in a spectrum auction in 2014.

Martin Halliwell, Chief Technology Officer at SES, said, “Thanks to the Airbus, Arianespace and SES teams, SES-14 is able to fulfil its planned satellite mission of bringing better picture quality TV content to people across Latin America, as well as delivering high-speed broadband services to airline passengers flying over the Americas and North Atlantic routes. Enterprises and communities within the region will also be able to access the reliable connectivity provided by SES-14. SES-14 is key to SES's future growth trajectory and is part of our ongoing strategy to develop innovative capabilities for specific and growing markets.” 

SES-14 was launched on an Ariane 5 rocket from the Guiana Space Centre in Kourou, French Guiana. SES-14 was built by Airbus Defence and Space and is an all-electric satellite. The satellite also features a Digital Transparent Processor (DTP), which increases payload flexibility and will provide customised connectivity solutions to SES's customers.

Mission Update: NASA’s GOLD Powers on for the First Time

October 2, 2018

NASA’s Global-scale Observations of the Limb and Disk, or GOLD, mission powered on the GOLD instrument for the first time after launch on Jan. 28, 7:23 p.m. EST. The systems engineers successfully established communication with the GOLD instrument and its detector doors opened when commanded. After their tests, the engineers powered off the instrument the same day, at 7:40 p.m. EST. The instrument will remain powered off until its host satellite, SES-14, reaches geostationary orbit and GOLD operations commence later this year.

GOLD will be at the forefront of exploring and understanding near-Earth space, which is home to astronauts, radio signals used to guide airplanes and ships, and satellites that provide our communications and GPS systems. The more we understand about this region, the more we can protect our assets in space. GOLD will explore a little understood area close to home, but historically hard to observe: the lowest reaches of space, a dynamic area in Earth’s upper atmosphere that responds both to space weather above, and the lower atmosphere below. GOLD will collect observations with a 30-minute cadence, much higher than any mission that has come before it. This enables GOLD to be the first mission to study the day-to-day weather of the upper atmosphere – the overlapping thermosphere and the ionosphere – rather than its long-term climate.
