An Intelsat high-power satellite at 58°W serving the Americas with C-band and high-power Ku-band capacity. IS-21 is a primary Intelsat asset for Brazil — the world's fifth-largest country by area and a major satellite market. Its high-power Ku-band beams enable direct-to-home broadcasting across Brazil's vast interior, where terrestrial television struggles to reach and satellite is the standard entertainment medium for rural households.
