Sirius FM-6

Sirius FM-6 is a new, high-power satellite designed to operate in a Geostationary orbit (GEO). This satellite is the seventh SSL-built spacecraft in the SiriusXM Radio fleet and provides nearly double the power of the satellites in SiriusXM's existing, in-orbit constellation, continuing to improve service for SiriusXM subscribers. Sirius FM-6 carries an X-band uplink and an S-band downlink payload. With almost 20 kilowatts end-of-life power, it is one of the world's most powerful satellites built. The satellite launched in October 2013.
