Communications payload
Intelsat 14 has a C-band and Ku band payload, each of which is further divided to provide service to 2 each coverage areas.[2]
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 Ku 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 Ku 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 Ku band channels. This experimental payload is known as IRIS (Internet Routing in Space) demonstration.[3]
