SSL launched SIRIUS FM-5 in 2009. It is the first geostationary satellite in the SIRIUS constellation, which already includes three SSL built satellites in highly elliptical inclined orbits (HEIOs). SIRIUS FM-5 is the highest-powered satellite in the SIRIUS fleet, with end-of-life power capability of nearly 20 kilowatts. The satellite supplements the existing constellation in providing radio service to the continental U.S. as well as Canada.
