AMC-5R is being built for Princeton, NJ-based SES AMERICOM under a contract for up to five virtually identical satellites. AMC-5R is a hybrid C- and Ku-band spacecraft that will serve the Continental United States and portions of the Caribbean, replacing satellites currently in orbit at 79 degrees West Longitude. In addition to AMC-5R, Orbital is currently under contract to provide two additional satellites.
The AMC-5R satellite is based on Orbital’s Enhanced STAR™ 2.4 bus, the largest and most powerful GEO communications satellite the company builds. The spacecraft will each carry 24 active C-band and 24 Ku-band transponders of 36 MHz capacity each. Six of the channels in each band can be cross-strapped to the opposite band, enabling new service capability. The spacecraft will generate approximately five kilowatts of payload power and will have two 2.3 meter deployable reflectors.
