Intelsat 14 is a communications satellite owned by Intelsat located at 45° West longitude, serving the Americas, Europe, and African markets. Intelsat 14 replaced Intelsat 1R which was at the end of its design life. It was built by Space Systems Loral, as part of its LS-1300 line.

Communications payload

Intelsat 14 has a C-band and K_u band payload, each of which is further divided to provide service to 2 each coverage areas.

The C-band payload has an Americas beam which covers the southern part of the United States, all of Mexico, Central America, and all of South America. A second C-band beam provides coverage for Western Europe and Africa.

The K_u band payload also has an Americas beam which covers the Alabama, Georgia and Florida, all of the Caribbean, Central America and all of South America except Brazil. The K_u band US/Europe/Africa beam covers the southern eastern United States, Western Europe, and the northern western African countries.

Intelsat 14 also carries an experimental radiation-tolerant IP router payload that can be connected to several of the C and K_u band channels. This experimental payload is known as IRIS (Internet Routing in Space) demonstration.
