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.[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 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.[3]
