SES-17, is a high throughput all electric geostationary communications satellite owned and operated by SES, and designed and manufactured by Thales Alenia Space.

[8] SES-17 is SES's first geostationary Ka-band high-throughput satellite, and the first one to include a fully digital payload, using Thales' Spaceflex VHTS Processor, a Digital Transparent Processor (DTP) developed with support from the French space agency, Centre National d'Études Spatiales CNES and the European Space Agency (ESA) [9] to provide in-orbit frequency plan flexibility so mobility customers can change their networks in real time in response to changing bandwidth demands, implementing broadcast, multicast or mesh network as required, and improving efficiency in throughput and bandwidth use.

[10] Along with SES's medium Earth orbit satellite constellation, O3b mPOWER, SES-17 is managed through the Adaptive Resource Control (ARC) software system developed jointly between SES and Kythera Space Solutions, autonomously optimizing space and ground resources, on-the-fly, in accordance with customers' changing needs.

[4] In September 2019, SES announced it had partnered with satellite payload and network management systems developer, Kythera Space Solutions to develop the ARC (Adaptive Resource Control) software to enable the dynamic control and optimisation of power, throughput, beams and frequency allocation on SES-17 and other future high-throughput satellites and their networks.

[2] In July-August 2022, Spirit Airline's inflight Internet service (using Thales' FlytLIVE) transitioned from Hughes Network Systems satellites to SES-17 to become "the fastest Wi-Fi service of any US-based airline" with connection speeds of up to 400 Mbps for A320 and A321 passengers across all Spirit routes.
