Intelsat 11 is a communications satellite owned by Intelsat and located at 43.0° West longitude, serving the Americas market.[1] Intelsat 11 replaced Intelsat 3R which was nearing the end of its design life.[2] Intelsat 11 was built by Orbital Sciences Corporation, as part of its STAR-2 line.[3] Intelsat 11 was formerly known as PAS-11. It was launched 5 October 2007 by an Ariane 5 GS.[4]

Intelsat 11 is designed to deliver C-band services to Intelsat's customers in the continental United States and also serve as DirecTV Latin America's Ku-band downlink for coverage of Brazil. Intelsat 11 is designed to assume the responsibilities of current customers for Intelsat 3R.[5]

In February 2023, Intelsat announced its intent to move Intelsat 11 to a backup satellite asset and allowing the satellite to drift to an inclined geosynchronous orbit with eventual intent to retire it to a graveyard orbit.[6]
