Satellite description

SES-17 is based on the three axis stabilised Spacebus Neo satellite bus. It will mass around 6,000 kilograms (13,000 lb), produce 15 kW of power and have a design life of 15 years.[1][2]

As all Spacebus Neo, it will use electric propulsion exclusively for both orbit raising and station keeping.[2]

It will have around 200 Ka band spot-beams to offer coverage over North America, South America, the Caribbean, Mexico, and the Atlantic Ocean mainly for aircraft connectivity. It will be SES's first pure Ka band satellite in the geostationary orbit and is expected to be launched on an Arianespace Ariane 5 rocket in H1 2021.[3][4][5]

History

On 12 September 2016, SES S.A. ordered its first Ka band high throughput satellite, SES-17, from Thales Alenia Space. It was to be built on the Spacebus Neo platform, weight 6,000 kilograms (13,000 lb), produce 15 kW of power and have a design life of 15 years. It would offer aviation connectivity services over North America, South America, the Caribbean, Mexico, and the Atlantic Ocean and was expected to launch in 2021. Its anchor customer was going to be FlytLIVE by Thales, which would be operation since 2017 thanks to the use of other SES satellites on orbit.[2][4] The project cost was expected to be around US500 million dollars.[5]

gollark: They seemed mostly fine with them. Not a huge amount of them actually *changed* anyway.
gollark: I think it's in `infocontext.txt`: they believed people were misled into thinking the other staff were not happy with rule changes.
gollark: Indeed!
gollark: OCaml.
gollark: It can parse tuples of integers.
