Intelsat S.A. (formerly Intel-Sat, Intelsat) is a Luxembourgish-American multinational satellite services provider with corporate headquarters in Luxembourg City and administrative headquarters in Tysons, Virginia, United States. Originally formed as International Telecommunications Satellite Organization ( ITSO, or Intelsat), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services.
In March 2023, rival satellite operator SES confirmed that it was in talks about a merger with Intelsat but in June 2023, it was announced that these discussions had ended.

Accessed 30 June 2023 On 30 April 2024, SES announced that an agreement had been reached to acquire Intelsat for US$3.1 billion, with the transaction expected to close in the second half of 2025. The acquisition was completed on 17 July 2025.
As of June 2022, Intelsat operated a fleet of 52 communications satellites which was then one of the world's largest fleets. In 2020, the company announced plans to procure, build and launch seven C-band satellites over the next several years. These C-band satellites will contribute to the acceleration of America's 5G buildout. In early 2022, the company announced contracts for four GEO software defined satellites (SDS), two in partnership with Airbus and two in partnership with Thales Alenia Space, that are scheduled to launch in 2023. These contracts point to the pursuit of a multi-year network transformation plan with investments designed to deliver higher speeds, more flexibility, redundancy, and backwards compatibility.
As of 2022, the company served approximately 1,800 customers and employed a staff of approximately 1,790 people.
On 6 April 1965, Intelsat's first satellite, the Intelsat I (nicknamed Early Bird), was placed in geostationary orbit above the Atlantic Ocean by a Delta D rocket.
In 1973, the name was changed and there were 81 signatories. Intelsat was "governed initially by two international agreements: The Agreement setting forth the basic provisions and principles and structure of the organization, signed by the governments through their foreign ministries, and an Operating Agreement setting forth more detailed financial and technical provisions and signed by the governments or their designated telecommunications entities", — in most cases, the latter are the ministries of communications of the party countries, but in the case of the United States, was the COMSAT (COMSAT), a private corporation established by federal legislation to represent the U.S. in international governance for the global communication satellite system. Intelsat at that time directly owned and managed a global communications satellite system, and structurally consisted of three parts:
The 1973 Agreement called for a seven-year transition from national to international management, but continued until 1976 to carve out "technical and operational management of the system to the Communications Satellite Corporation which served as the Manager of the global system under the interim arrangements in force from 1964 to 1973". Later phases of the transition resulted in full international governance by 1980. Financial contribution to the organization, its so-called "investment share", was strictly proportional to each member's use of the system, determined annually; and this corresponded to the weighted vote each would have on the Board of Governors.
Since its inception, Intelsat has used several versions (blocks) of its dedicated Intelsat satellites. Intelsat completes each block of spacecraft independently, leading to a variety of satellite manufacturing contractors over the years. Intelsat's largest spacecraft supplier by 2012 was Space Systems/Loral, having built 47 spacecraft (Intelsat 20) by that time.
The network in its early years was not as robust as it is now. A failure of the Atlantic satellite in the spring of 1969 threatened to stop the Apollo 11 mission; a replacement satellite went into a bad orbit and could not be recovered in time; NASA used undersea cable telephone circuits as an alternative to route Apollo's communications to NASA during the mission. During the Apollo 11 moonwalk, the Moon was over the Pacific Ocean, and so other antennas were used, as well as Intelsat III, which was in geostationary orbit over the Pacific.
Intelsat Americas-7 (known formerly as Telstar 7 and known as Galaxy 27 since on 1 February 2007) experienced a several-day power failure on 29 November 2004. The satellite returned to service with reduced capacity.
Intelsat was sold for US$3.1 billion in January 2005 to four private equity firms: Madison Dearborn Partners, Apax Partners, Permira and Apollo Global Management. The company acquired PanAmSat on 3 July 2006, and was then the world's largest provider of fixed satellite services, operating a fleet of 52 satellites in prime orbital locations.
In June 2007, BC Partners announced they had acquired 76% of Intelsat for about €3.75 billion.
In 2015, Intelsat reincorporated in Delaware and became Intelsat Corporation.
There were negotiations in 2017 that Intelsat could potentially merge with SoftBank Group-backed Eutelsat OneWeb. However, on 1 June 2017, it was announced that the bondholders would not accept the offer and that the potential merger would be terminated as of 2 June 2017.
Public reporting showed that the company had been considering bankruptcy protection as early as February 2020,
According to company statements, the company was hoping to restructure so that it could raise requisite capital to launch new satellite technology in 2022/2023, at a cost of some US$1.6 billion. The technology could compress existing licensed C-band spectrum customers into just forty per cent of the spectrum used in 2019. The release of spectrum would enable the company to receive up to US$4.86 billion in "spectrum clearing payments" from the FCC for clearing the spectrum by December 2023, two years ahead of the FCC baseline plan.
According to then company CEO, Stephen Spengler, post bankruptcy, the company plans to pursue aggressive network innovation plans, and strategic growth initiatives, including building a software-defined 5G network. The company also announced a new board of directors, led by Lisa Hammitt, executive vice president and chief technology officer at Davidson Technologies.
The plan is that the fuel-depot vehicle would maneuver to several satellites, dock at the target satellite's apogee kick motor, remove a small part of the target spacecraft's thermal protection blanket, connect to a fuel-pressure line and deliver the propellant. "MDA officials estimate the docking maneuver would take the communications satellite out of service for about 20 minutes".
On 25 February 2020, a Northrop Grumman robotic servicing spacecraft, Mission Extension Vehicle 1 (MEV 1) docked with the Intelsat 901 satellite. The MEV 1 spacecraft has provided propulsion capabilities to Intelsat 901 to extend its usable life for five years.
Intelsat provides service to over 600 Earth stations in more than 149 countries, territories and dependencies. By 2001, Intelsat had over 100 members. It was also this year that Intelsat privatized and changed its name to Intelsat.

as Intelsat formally withdrew from the C-Band Alliance. The C-Band Alliance was an industry consortium of the major satellite operators. The consortium had been formed to lobby U.S. regulator, the Federal Communications Commission (FCC) regarding the reassignment and payment for the legacy 5G spectrum of its members.

In-space refueling demonstration project
Intelsat has agreed to purchase one-half of the propellant payload that an MDA Corporation spacecraft satellite-servicing demonstration project would take to geostationary orbit. [[Catching up|Orbital maneuver]] in orbit with four or five Intelsat communication satellites, a load of of fuel delivered to each satellite would add somewhere between two and four years of additional service life. A near-end-of-life Intelsat satellite will be moved to a graveyard orbit above the geostationary belt where the refueling will be done, "without consequence" to the Intelsat business.
the business model was still evolving. MDA "could ask customers to pay per kilogram of fuel successfully added to [each] satellite, with the per-kilogram price being a function of the additional revenue the operator can expect to generate from the spacecraft's extended operational life".
