It is positioned in Geostationary orbit at a longitude of 110° West, from where it is used to provide direct broadcasting services to the United States.

EchoStar X was built by Lockheed Martin, and is based on the A2100AXS satellite bus. It is equipped with 42 J band (IEEE {{Ku band}}) transponders, and at launch it had a mass of {{convert|4333|kg}}, with an expected operational lifespan of 16 years<ref name="UCS">{{cite web|url=http://www.ucsusa.org/nuclear_weapons_and_global_security/space_weapons/technical_issues/ucs-satellite-database.html|title=UCS Satellite Database|publisher=Union of Concerned Scientists|date=2009-07-01|access-date=2009-08-08}}</ref><ref name="GSP">{{cite web|url=http://space.skyrocket.de/doc_sdat/echostar-10.htm|title=Echostar 10|first=Gunter|last=Krebs|publisher=Gunter's Space Page|access-date=2009-08-08}}</ref>

The satellite was launched using a Sea Launch Zenit-3SL carrier rocket flying from the Ocean Odyssey launch platform.
