Intelsat 605
Intelsat 605, previously named Intelsat VI F-5, was a communications satellite operated by Intelsat. Launched in 1991, it was the fourth of five Intelsat VI satellites to be launched. The Intelsat VI series was constructed by Hughes Aircraft, based on the HS-389 satellite bus.
Intelsat 605 was launched at 23:15:13 UTC on 14 August 1991, atop an Ariane 4 44L carrier rocket, flight number V45. The launch took place from ELA-2 at Kourou, and placed Intelsat 605 into a geosynchronous transfer orbit. The satellite raised itself into its final geostationary orbit using two liquid-fuelled R-4D-12 engines, with the satellite arriving in geostationary orbit on 20 August 1991.
Intelsat 605 initially operated in a geostationary orbit with a perigee of 35,756 kilometres (22,218 mi), an apogee of 35,818 kilometres (22,256 mi), and 0 degrees of inclination. The satellite carried 38 IEEE C band and ten IEEE Ku band transponders, and had a design life of 13 years and a mass of 4,296 kilograms (9,471 lb).
Intelsat
Intelsat, S.A. is a communications satellite services provider.
Originally formed as International Telecommunications Satellite Organization (INTELSAT), it was—from 1964 to 2001—an intergovernmental consortium owning and managing a constellation of communications satellites providing international broadcast services.
As of March 2011, Intelsat operates a fleet of 52 communications satellites, which is one of the world's largest fleet of commercial satellites. They claim to serve around 1,500 customers and employ a staff of approximately 1,100 people.
History
The intergovernmental organization (IGO) began on 20 August 1964, with 11 participating countries. 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 80 signatories. 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.
Intelsat 20
Intelsat 20 is a geostationary communications satellite which is operated by Intelsat. It was constructed by Space Systems Loral, and is based on the LS-1300 satellite bus. It was launched on 2 August 2012, and replaces the Intelsat 7 and Intelsat 10 spacecraft at 68.5º East longitude. It is fully operational since September 2012.
Intelsat 20 carries 24 IEEE C-band (NATO G/H-band), 54 IEEE Ku band (NATO J-band) transponders and 1 Ka band transponder. The C-band covers the Asia-Pacific region, while the Ku band transponders is used for Direct to Home broadcasting to Asia, Africa, and the Middle East. The Ka band payload provides coverage to the Middle East and Central Asia

Intelsat 11
Intelsat 11 is a communications satellite owned by Intelsat planned to be located at 43° W longitude, serving the Americas market. Intelsat 11 is intended to replace Intelsat 3R which is nearing the end of its design life. It was built by Orbital Sciences Corporation, as part of its Star-2 Bus line. Intelsat 11 was formerly known as PAS-11. It was launched 2007-10-05 by an Ariane 5 GS.
The customers for Intelsat 11 are expected to include the current customers for Intelsat 3R.
