Galaxy 11 was an American geostationary communication spacecraft that was launched from Kourou by an Ariane 4 rocket. The 2,775 kg, 10.4 kW spacecraft carried 24 C-band (20 W), and 40 Ku-band (24 at 75 W, and 16 at 140 W) transponders to provide voice and video communications to North America and Brazil, after parking eventually over 91 degrees W longitude.
The 20-watt C-band transponders will be used primarily for cable television customers. The Ku-band payload offers two power levels: 140 watts for video distribution, and 75 watts for data networks and other general communications services. This gives Galaxy 11 a total payload of 64 active transponders, for much greater capacity than the largest satellites now in its fleet.
