Spaceway F1 is part of DirecTV’s constellation of direct broadcast satellites. The satellite was launched via a Zenit 3SL rocket from Sea Launch’s Odyssey equatorial platform on April 26, 2005. Its operational position is in geosynchronous orbit 35,800 kilometres (22,200 mi) above the equator at 102.8 degrees west longitude. SPACEWAY-1 is a Boeing 702-model satellite with a 12-year life expectancy. It is expected to provide high definition television to DirecTV customers with its K_a-band communications payload. DirecTV is not expected to make use of the broadband capabilities on SPACEWAY-1 even though it was originally built by Boeing for this purpose.
