Orbital is building the Intelsat-23 (IS-23) GEO communications satellite for Intelsat, LLC. IS-23 will generate 4.8 kilowatts of electrical payload power and carry 15 active Ku-band and 24 active C-Band transponders. The spacecraft will provide communications services for the Americas, Caribbean, Western Europe, Africa and selected islands of the Pacific and Atlantic oceans. Designed for a useful life of at least 15 years, the IS-23 satellite will be located in orbit at 307 degrees East Longitude following its launch in late 2011. The IS-23 is the 10th Orbital-built geosynchronous communications satellite in the Intelsat fleet.
