Spaceway-1 {{cite web|url=https://spaceref.com/press-release/directvs-spaceway-f1-satellite-launches-new-era-in-high-definition-programming-next-generation-satellite-will-initiate-historic-expansion-of-directv/|title=DIRECTV's Spaceway F1 Satellite Launches New Era in High-Definition Programming; Next Generation Satellite Will Initiate Historic Expansion of DIRECTV|date=2005-04-26|publisher=SpaceRef|work=DirecTV|access-date=2023-10-07}} was a part of AT&T's constellation of direct broadcast satellites.

The satellite was launched via a Zenit-3SL rocket from Sea Launch's Odyssey equatorial ocean platform on 26 April 2005.

Its operational position was in geosynchronous orbit {{convert|35800|km}} above the equator at 102.8° West longitude. Spaceway-1 was a Boeing 702-model satellite with a 12-year operational life expectancy.

It provided high-definition television to DirecTV customers with its K_a-band communications payload. DirecTV did not make use of the broadband capabilities on Spaceway-1 even though it was originally built by Boeing for this purpose.
