Intelsat公司的Intelsat 18商业通讯卫星，采用轨道科学公司的Star-2平台，将为美国、澳大利亚、太平洋岛屿地区等提供服务。

Orbital Sciences Corporation announced in August 2008 that it has been selected by Intelsat, Ltd. to design, build and deliver the Intelsat-18 (IS-18) commercial communications satellite.

The satellite will be based on Orbital's flight-proven Star-2 platform and will generate approximately 4.9 kilowatts of payload power. The IS-18 satellite will carry 24 C-band transponders to cover the Northern and Southern Hemispheres and 12 Ku-band transponders to provide services to the United States, French Polynesia, Australia, New Caledonia and other Pacific Islands. Following its launch and deployment, the spacecraft will be located in geosynchronous orbit (GEO) at 180 degrees East longitude. The IS-18 satellite will replace Intelsat's IS-701 spacecraft.
