Intelsat is a technology company founded in 1964 and based in Luxembourg . It offers the transmission capacity for national and international communication, such as voice, data transmission, Internet connection and television transmission using geostationary communication satellites for a fee. Since the start of the groundbreaking Intelsat I , these satellites have been continuously developed and their transmission capacity increased. Intelsat satellites broadcast in the C-band and Ku-band frequencies.

The company's shares are traded on the New York Stock Exchange .

Intelsat I , the first commercial was communications satellite on a geostationary orbit . It was launched into space on April 6, 1965 on the tip of a Delta-D rocket.

The satellite was christened Early Bird by the New York Times for lack of a catchy name . It was acquired by the US news company Comsat and years later sold on to the global news satellite organization Intelsat. Early Bird broadcast the television entertainment program “Premiere in Space” on both sides of the Atlantic on May 2, 1965 from its position 35,800 km above the equator at 28 ° west longitude.

Early Bird was able to broadcast 240 phone calls or a television broadcast. Without a drive, it weighed only 38 kilograms. The transmission power was 40 watts and the service life was 1.5 years. It was 72 centimeters in diameter and 59 centimeters long.

The operating organization was eleven participating countries as at August 20, 1964 In ternational Tel eCommunications satellite founded ellite Consortium. 1973 with 80 participating states the name was changed to International Telecommunications Satellite Organization (ITSO). On July 18, 2001, after 37 years as an intergovernmental organization, Intelsat was privatized and the name Intelsat has been used ever since . In August 2004, the company was sold to four US and UK private equity firms for $ 3.1 billion : Madison Dearborn Partners, Apax Partners , Permira and Apollo Global Management . A merger with PanAmSat has been initiated.

In 2004 Intelsat bought a number of satellites for the American market ( Telstar 5, 6, 7, 8 and 13) from the Canadian company Loral Skynet . These were added to the fleet under the name Intelsat Americas .

In June 2007, the financial investor BC Partners bought 76 percent of the company for $ 5 billion. Intelsat had its headquarters in Bermuda until December 2010, after which it was relocated to Luxembourg. However, the operational headquarters are based in McLean , Virginia (USA).

In 2015 there were unusual maneuvers by a Russian satellite. A Russian satellite of the Lutsch series initially occupied a geostationary position between two Intelsat satellites for five months, but then left this position and approached an Intersal satellite within 10 kilometers. The satellite then approached the Intelsat 905 .

In May 2020, Intelsat declared itself insolvent in the United States and applied for Chapter 11 bankruptcy protection .
