Intelsat S.A. awarded a contract to Boeing to provide a second ultra-high frequency (UHF) payload on another of the four commercial communications satellites that Intelsat ordered from Boeing last year. The second UHF hosted payload will be installed on the IS-27 satellite. The payload will offer 20 25-KHz UHF channels capable of serving the U.S. government and other Intelsat clients around the world. The second payload will be identical to the UHF payload for the Australian Defence Force that will be hosted on the IS-22 satellite and launched in 2012. Boeing is building the four Intelsat satellites and the two hosted payloads at its satellite factory in El Segundo, CA. IS-27 is planned to operate over the Atlantic Ocean region at 55° west longitude and will provide simultaneous operation of 39 C- and Ku-band transponders that deliver optimized video, network and voice services to the Americas and Europe.
