History
On 12 September 2016, SES ordered the SES-17 dedicated Ka-band high-throughput satellite from Thales Alenia Space of France and Italy, the main contractor for SES's O3b satellites. Offering mobility connectivity services over the Americas and the Atlantic Ocean, SES-17 was expected to launch in 2020 with the FlytLIVE airline passenger connectivity service from Thales Avionics as its anchor customer. Prior to the launch of SES-17, FlytLIVE would use capacity contracted by SES on Hughes's EchoStar XVII and EchoStar XIX satellites, along with SES's own AMC-15 and AMC-16 satellites.[5] The cost of the satellite and launch, and the network of gateways on the ground is expected to be around US$500 million.
In September 2017, SES announced that Arianespace had been selected to launch SES-17 in 2021.
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.[6]
SES's 2020 Annual Report, released in March 2021, said that SES-17 was expected to launch in July 2021.[7] In April 2021, Arianespace projected a launch in August 2021,[8] then, in September 2021 a launch on 22 October 2021. After a small delay caused by technical issues with the launch pad, the launch was successfully carried out on 24 October 2021 at 02:10 UTC.[9]
In May 2022, SES-17 reached its intended orbital position at 67.1° west[10] and, after testing, became fully operational in June 2022.[1]
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.[11][12][13]
In August 2023, SES announced that the combined contract backlog for SES-17, along with the O3b mPOWER high-throughput MEO satellite constellation (expected to begin commercial service by the end of 2023) is now in excess of US$1 billion (gross $1,025 million, fully protected $835 million).[14]
