SES S.A. is a Luxembourgish communications satellite operator supplying video and data connectivity worldwide to broadcasters, content and internet service providers, mobile and fixed network operators, governments and institutions.[6][7]
SES owns and operates over 70 satellites in two different orbits: geostationary orbit (GEO) and medium Earth orbit (MEO).[8] These include European Astra TV satellites, the O3b and O3b mPOWER data satellites and others with names including AMC, Ciel, NSS, Quetzsat, YahSat and SES.
In April 2024, SES announced the acquisition of satellite services provider, Intelsat to create a more competitive multi-orbit satellite operator.[9][10] The acquisition was cleared by the UK Competition and Markets Authority in May 2025,[11] and by the European Commission in June 2025.
The merger cleared the final regulatory hurdle when the US Federal Communications Commission granted its approval of the deal in July 2025.
The acquisition of Intelsat was completed on 17 July 2025 after receiving the required international regulatory approvals.[12][13]
Based in Betzdorf, Luxembourg, and founded in 1985 as Société Européenne des Satellites, the company was renamed SES Global in 2001 and has been simply "SES" since 2006.The company's stock is listed on the Luxembourg Stock Exchange and Euronext Paris with the ticker symbol SESG and is a component of the LuxX, CAC Next 20 and Euronext 100stock market indexes.
A book, High Above, telling the story of the founding of SES and the development of its first Astra satellites was published in 2010 to mark the company's 25th Anniversary, and was followed by Even Higher in 2012 and Beyond Frontiers in 2016.
History
Early years
SES was formed on the initiative and support of the Luxembourgish government in 1985 as Société Européenne des Satellites (SES).The Grand Duchy of Luxembourg remains a major shareholder.In December 1988, as Europe's first private satellite operator, SES launched its first satellite, Astra 1A, to the 19.2° East orbital position.Rupert Murdoch's Sky TV, along with German broadcasters Pro7, Sat.1, and RTL were among Astra's first major customers.
By 1990, Astra was broadcasting to 14 million cable and DTH (Direct to Home) viewers. SES was the pioneer of 'co-location' by which several satellites share the same orbital position to provide mutual backup and increase the number of channels available to a fixed receiving dish, creating what became known as a 'satellite neighbourhood'. Astra's prime slot, 19.2° East, saw as many as eight satellites sharing the position simultaneously and helped to build up Astra's reputation for reliability.
Rapid growth in Germany, in what would become Astra's largest European market, was helped by the German government's decision to liberalize the installation of dishes in 1991. In this time SES became the leading satellite system providing direct-to-home transmission, and became the world's largest satellite platform for TV distribution.
In 1996, after the launch of Astra 1E, SES pioneered digital satellite transmission with the French Canal+.In 1998, SES launched Astra 2A for the UK market, transmitting at the new orbital position 28.2° East, and eventually moving all of its United Kingdom and Ireland transmission capacity to this orbital slot. In the same year, SES went public on the Luxembourg Stock Exchange trading as SESG (in 2005 SES would also list on the Paris Euronext).
Global expansion
From 1999, SES began a period of ambitious global expansion beyond its European home market. Geographic expansion went hand-in-hand with the diversification of SES' services beyond just TV broadcasting, to cover telecommunication services for businesses, telecommunications companies and government customers, as well as broadband access and technical consultancy services.
In 1999, SES acquired a 34.13% stake in Hong Kong-based satellite operator AsiaSat and took a foothold in Asia and the Pacific region.
In 2000, SES acquired 50% of Scandinavian satellite broadcaster Nordic Satellite AB (NSAB),[14] later renamed SES Sirius, which strengthened SES' coverage in northern and eastern Europe.The same year, SES also took a participation of 19.99% in Brazilian satellite operator Star One, gaining a first presence in Latin America.
In 2001, SES bought 28.75% of Argentina's Nahuelsat and acquired GE Americom, giving it a solid presence in the important North American market.This resulted in the formation of SES Global, a corporate entity with two operating companies, SES Astra and SES Americom.
Global operator
In August 2011, the Astra 1N satellite was launched to the 28.2° East orbital position,[28] and in September 2011, the QuetzSat 1 satellite was launched to 77.0° West[29]
In February 2012, SES-4 was successfully launched to become SES' 50th satellite and the largest, heaviest and most powerful in the fleet.[30] In July 2012, SES-5, the 51st SES Satellite was launched from Baikonur, Kazakhstan to 5.0° East with 36 Ku-band transponders to provide coverage over Sub-Saharan Africa and the Nordic and the Baltic regions in Europe, and 28 C-band transponders for Europe, Africa and the Middle East.[31]
Recent events
In February 2024, Adel Al-Saleh took up the position of SES Chief Executive Officer (following his appointment in October 2023). Interim CEO, Ruy Pinto (previously Chief Technology Officer) became Strategic Advisor to the CEO.[143]
In February 2024, SES announced that Virgin Voyages will be the first cruise line to deploy the SES Cruise mPOWERED + Starlink PRO internet service that uses both SES' O3b mPOWERMEO satellites and SpaceX's StarlinkLEOsatellite constellation to provide cruise passengers with internet, social media and video calls at up to 1.5 Gbit/s per ship.[144]
In April 2024, SES announced that the O3b mPOWERmedium-Earth orbit (MEO) satellite system is operational, and services would be rolled out to customers “in the coming months”.The six O3b mPOWER satellites required for the operational start are in place, with seven more satellites, to increase the system capacity, under construction and due to launch over the next two years.
Business and services
SES provides services through two business units, SES Media (formerly SES Video) and SES Networks, for video-centric and data-centric markets, respectively.[4]
SES Media
(46% of revenue)[4] SES Media's business comprises video distribution and video services.Video distribution delivers video content via Direct-to-Home, Direct-to-Cable and Internet Protocol television (IPTV) platforms, and includes wholly owned subsidiary HD+, the direct-to-consumer high-definition digital satellite TV platform in Germany.Video services encompasses technical ground services, such as content management, playout, encryption, satellite uplinks and interactive services, to broadcasters worldwide.
SES has been a major player in the development of the direct-to-home market in Europe and the cable TV and Direct-broadcast satellite (DBS) markets in the United States.SES satellites transmit a variety of digital formats from radio to Ultra High Definition TV (UHDTV) and the company has been instrumental in defining technical standards for broadcast and interactive media.
At the end of 2022, SES satellites carried over 8000 TV channels, including more than 3000 HD and UHD channels, to more than 1 billion people in 369 million homes globally, or regionally as follows:[162][163]
In March 2022, SES reported that the breakdown of revenue to SES Video (now SES Media) by different sectors was as follows:[162]
SES Networks
(54% of revenue)[4] SES Networks provides capacity-on-demand and managed connectivity services in markets as follows:[7][164]
In particular, SES Networks uses the O3b and O3b mPOWER satellites in medium Earth orbit (with a latency of less than 150 ms) and SES-17 and GovSat in geostationary orbit.[162]
In March 2022, SES reported that the breakdown of revenue to SES Networks by different sectors was as follows:[162]
Business reach
SES has customers across the World, with revenue by country in 2023 (according to clients' billing addresses) as follows:[165]
Innovations
SES has pioneered many industry technological developments, including DTH transmission, co-location of satellites, free-to-air broadcast neighbourhoods, digital broadcasting, HDTV[166] and 3DTV.[167][168] SES has also helped develop innovative reception technology such as the first home dish LNBFs, Universal LNBs, optical fibre signal distribution and the Sat-IP system for receiving and distributing satellite signals over home computer networks.
SES has pioneered the broadcast of Ultra High Definition TV (UHDTV) and helped to establish the international technical standards for UHDTV broadcast and reception.SES first produced demonstration UHDTV broadcasts in 2012, transmitted the first HEVC-standard UHDTV in 2013, via Astra 19.2° East,[169] and the first next generation 8K Ultra HD demo in May 2018, via the Astra 3B satellite at 23.5°E.[170] SES broadcast the first live UHDTV satellite broadcast in November 2014 (Linkin Park’s concert at the O2 World in Berlin)[171] and Europe's first free-to-air Ultra HD channel, Pearl TV, launched in September 2015 via Astra 19.2° East[172] A continuous UHDTV demonstration channel has broadcast to Europe from SES's Astra 19.2° East satellite position since 2014 and SES now delivers 12 demo channels via its main orbital positions across the globe.[173] As of 2020, SES was broadcasting over 50 Ultra HD channels worldwide.[174]
SES-8 was the first geostationary satellite to be launched (in 2013) by SpaceX.[175][176] The SES-10 satellite was launched in March 2017 (delayed from October 2016 due to a pad explosion and subsequent loss of a Falcon 9 booster in September 2016[177]) on the first SpaceX launch with a 'flight-proven' (reused) Falcon first stage, recovered from a previous launch.[178] The SES-12, SES-14 and SES-15 satellites (launched in June 2018, January 2018 and May 2017, respectively) are constructed with an electric plasma propulsion system for orbit raising and in-orbit manoeuvres[179] to save weight and enable a larger communications payload to be included.SES reckons that SES-12 would weigh some 4700 kg more with a conventional
SES operates the world’s first multi-orbit communications satellite network, combining geostationary orbit satellites’ wide coverage and reliability, and a medium Earth orbitsatellite constellation's low latency and high data throughput.In conjunction with Kythera Space Solutions, SES developed Adaptive Resource Control (ARC) software to dynamically control and optimise power, throughput, and beam and frequency allocation across the multi-orbit network of the O3b and O3b mPOWER medium Earth orbit satellite system, and SES-17 and future geostationary high-throughput satellites.[180][181][182]
SES is the first commercial customer for Space Infrastructure Servicing (SIS) future satellite life extension mission, following an agreement in June 2017 with MacDonald, Dettwiler and Associates (MDA).The SIS craft was being built by Space Systems/Loral (SSL), a manufacturing subsidiary of MDA, for the United States Defense Advanced Research Projects Agency (DARPA)'s Robotic Servicing of Geosynchronous Satellites (RSGS) programme, and will refuel an SES satellite running low on propellant while still in orbit to lengthen its service life.[183] SSL (as Maxar) abandoned the DARPA contract in 2019.[184]
SES leads a consortium to develop the pioneering laser-linked optical quantum cryptography satellite Eagle-1 in conjunction with the European Space Agency.Due to launch in 2026, Eagle-1 will validate quantum key distribution (QKD) technology that uses the quantum properties of photons for long distance transmission of encryption keys in ultra-secure data communications, and will be the first sovereign European end-to-end space-based QKD system.[108][109]

In May and September 2011, SES restructured and rebranded the company to streamline the organisation's activities under a single management team and one main brand (SES), incorporating the company's two previous operating entities, SES Astra and SES World Skies.[26][27]
In September 2012, Astra 2F was successfully launched from Kourou in French Guiana, the first of three "next generation" satellites at the second Astra orbital position at 28.2° East.The satellite has Ku-band coverage of all Europe, the British Isles and sub-Saharan Africa for DTH television, and Ka-band coverage of Central Europe for the SES Broadband satellite internet service.[32]
SES-6 was launched from Baikonur, Kazakhstan, on 3 June 2013 to 40.5° East, to replace NSS-806 and provide continuity of service and expansion capacity in C-band for Latin America and the Caribbean.The satellite has 43 C-band and 48 Ku-band transponders with comprehensive coverage of North America, Latin America, Europe and the Atlantic Ocean.[33]
Astra 2E was launched to the Astra 28.2° East position from Baikonur in Kazakhstan on 30 September 2013 to provide free-to-air and encrypted DTH digital TV and satellite broadband services for Europe and the Middle East.[34] The successful launch followed a 10-week delay due to the postponement of all launches by launch services provider ILS after a catastrophic failure of the rocket in a previous launch.[35]
In December 2013, SES-8 was launched from Cape Canaveral using a SpaceXFalcon 9 v1.1, the first geostationary satellite to be launched with a SpaceX rocket.[36]
In March 2014, Astra 5B was launched as SES' 56th satellite to the Astra 31.5° East position from Kourou in French Guiana to provide transponder capacity and extend geographical reach over Central and Eastern Europe, Russia and the Commonwealth of Independent States (CIS) for DTH, direct-to-cable and contribution feeds to digital terrestrial television networks.[37]
In April 2014, Romain Bausch stepped down as president and CEO of SES, a position he had held since 1995 overseeing the growth of the company from a European Direct-to-Home satellite system with four satellites into a global satellite industry leader operating a fleet of more than 50 satellites. Bausch continues to serve SES as a non-executive Director, and is elected to take the role of chairman at the start of 2015. He was succeeded as CEO by Karim Michel Sabbagh.[38]
In May 2014 SES announced that the engineering services division, SES TechCom had joined with the Luxembourg Government and the Minister for Cooperation and Humanitarian Action, and five Non-governmental organisations (NGO) – Archemed, Fondation Follereau, Friendship, German Doctors and Médecins Sans Frontières to form Satmed, an eHealth platform to improve public health in emerging and developing countries, especially in remote areas with poor connectivity.[39]
In July 2014, SES announced that nearly half of the SES satellite fleet is controlled from the new satellite operations center (SOC) opened at its sales and engineering offices in Princeton, New Jersey.23 satellites are controlled from Princeton with the remainder operated from SES's global headquarters in Luxembourg.[40]
Astra 2G, the final "next generation" satellite for the 28.2° East orbital position was launched from the Baikonur in December 2014 to deliver broadcast, VSAT and broadband services to Europe, the Middle East and Africa, and to connect West Africa to Europe via Ka-band.[41]
On 13 January 2015, SES announced that it plans to procure and launch a satellite in partnership with the Luxembourg Government, to be called GovSat-1.Jointly owned, the satellite is launched in 2017 to an orbital position above Europe and provide governmental and military communications in the X-band and Ka-band with coverage of Europe, the Middle East, Africa and Asia-Pacific.[42]

On 11 October 2017, a flight-proven (refurbished) SpaceXFalcon 9 rocket launched the SES-11 satellite to the geostationary orbital position of 105.0° West. The launch was originally set for late 2016 but suffered a year-long delay because of SpaceX's September 2016 Falcon 9 explosion. SES-11 was built by Airbus Defence and Space and is a dual mission satellite, with 24 Ku-band transponders marketed by EchoStar as EchoStar 105 to replace capacity on SES' AMC-15 satellite, and 24 C-band transponders marketed by SES as SES-11 for replacement capacity for AMC-18 delivering video, especially HD and UHD, to the United States, Mexico and the Caribbean.[58] Following positioning at 105.0° West and in-orbit testing, SES-11 was declared fully operational on 29 November 2017.[59]
In February 2018, SES teamed up with Intelsat (later joined by Eutelsat in July 2018) for a proposal to United StatesFederal Communications Commission (FCC) to form a consortium of satellite service providers to protect the quality and reliability of existing video and audio services to United States households downlinking in the 3700-4200 MHz C-band spectrum while enabling wireless operators to access 100 MHz of C-band spectrum for deployment of next generation 5G services in the United States.[60][61]
In March 2018, Saint Martin-based satellite TV provider KiwiSAT launched a new DTH platform to deliver about 130 channels (including 90 HD channels) of TV entertainment to consumers across the Caribbean using the SES-10 satellite at 67.0° West.[62]
In May 2018, SES broadcast an 8K television signal via its satellite system for the first time, as part of its Industry Days conference at the Luxembourg HQ.The 8K demonstration content, with a resolution of 7680 x 4320 pixels, a frame rate of 60 frames per second and 10-bit colour depth, was encoded in HEVC and transmitted at a rate of 80 Mbit/s via the Astra 3B satellite.[63]
In September 2018, in response to a Notice of Proposed Rulemaking of July 2018 from the United States Federal Communications Commission (FCC) to make the 3.7 to 4.2 GHz spectrum available for next-generation terrestrial fixed and mobile broadband services,[64] SES, along with Intelsat, Eutelsat and Telesat - together providing the majority of C-band satellite services in the United States, including media distribution reaching 100 million United States households - established the C-Band Alliance (CBA).The consortium's proposal to the FCC is to act as a facilitator for the clearing and repurposing of a 200 MHz portion of C-band spectrum to accelerate the deployment of next generation 5G services while protecting incumbent users and their content distribution and data networks in the US from potential interference.[65][66]
In April 2019, four O3bmedium Earth orbit (MEO) satellites were launched by Arianespace at the Centre Spatial Guyanais in Kourou, French Guiana to complete the constellation of 20 first generation satellites for the SES-owned network communications service provider.[67]
In May 2019, for the first time in Europe, 8K demonstration content was received via satellite without the need for a separate external receiver or decoder.At the 2019, SES Industry Days conference at Betzdorf, Luxembourg broadcast quality 8K content (with a resolution of 7680 x 4320 pixels at 50 frames/s) was encoded using a Spin Digital HEVC encoder (at a bit rate of 70 Mbit/s), uplinked to a single 33 MHz transponder on SES' Astra 28.2°E satellites and the downlink received and displayed on a Samsung 82in Q950RB production model TV.[68]
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 O3b mPOWER, SES-17 and other future high-throughput satellites and their networks, autonomously optimizing space and ground resources, on-the-fly, in accordance with customers' changing needs.[69][70]
In September 2019, SES became a Microsoft Azure ExpressRoute services partner to provide dedicated, private network connectivity from sea vessels, aircraft, and industrial or government sites anywhere in the world to the Azure cloud computing service, via both its geostationary and O3b medium Earth orbit satellites.[71]
In September 2019, SES announced a new Free-to-view DTH platform on Astra 1N at 19.2° East, encrypted using Verimatrix and carrying 30-40 channels from Russian-language OTT broadcaster Kartina TV for Russian-speaking diaspora across Europe with limited broadband connectivity.[72]
In September 2019, the media technical services provider MX1, a wholly owned subsidiary of SES, was merged into the SES Video division, dropping the MX1 brand and providing all broadcast and streamed content management, playout, distribution, and monetisation services under the SES name.[73]
In May 2020, SES released the results of the 2019 Satellite Monitor TV reception survey, which for the first time covered the Philippines.The survey found satellite TV is the second-most popular mode of TV reception in the Philippines with 17% of over 20.8 million TV households, behind terrestrial TV (66%), and that broadcasts from SES satellites reach 98% of Filipino satellite TV households.[74]
On 26 May 2020, SES elected to clear a portion of the C-Band spectrum in the United States, currently used for satellite TV services, in accordance with the Federal Communications Commission (FCC) order for the accelerated release of the 3.7-4.0 GHz portion of the band for 5G mobile broadband services.The SES Board of Directors approved US$1.6 billion for the procurement and launch of new satellites and other equipment and services for the migration of existing customers using the spectrum, which will be reimbursable through the FCC Clearinghouse.[75] In June 2020, SES announced that four new C-band satellites had been ordered for this purpose from United States manufacturers, Boeing and Northrop Grumman.SES-18 and SES-19 will be GEOStar-3 satellites designed, assembled, and tested by Northrop Grumman, and SES-20 and SES-21 will be all-electric 702SP satellites from Boeing.Each satellite will have ten 36 MHz C-band transponders for delivery of digital TV and data services, and will be launched in 2022 to orbital slots at 103.0° West, 131.0° West and 135.0° West.[76]
In July 2020, SES launched a free-to-air information channel, Fight COVID-19, across several satellites to combat the global coronaviruspandemic.Available to millions of households across Africa, Europe, and Asia-Pacific, and providing underserved and rural communities with critical information about how to limit the spread of the virus, the content is provided by trusted organisations such as UNICEF, AFP and other international and regional organisations.The channel is broadcast from SES-5 (5.0° East) for Sub-Saharan Africa, Astra 4A (5.0° East) for Europe and Ukraine, Astra 2F (28.2° East) for West Africa, NSS-12 (57.0° East) for Ethiopia and adjacent countries, and SES-9 (108.2° East) for the Philippines.[77]
In August 2020, SES ordered two C-Bandgeostationary TV satellites from Thales Alenia Space.SES-22 and SES-23 are the last of six satellites SES needs to relocate existing C-band services from a portion of the C-band spectrum in accordance with the Federal Communications Commission's plans to repurpose the frequencies for 5G cellular networks.[78]
