Encyclopedia
EchoStar X, also known as EchoStar 10, is an American
geostationary communications satellite
which is operated by EchoStar on behalf of Dish Network
. 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 ) transponder
s, and at launch it had a mass of 4333 kilograms (9,552.6 lb), with an expected operational lifespan of 16 years
The satellite was launched using a Sea Launch
Zenit-3SL
carrier rocket flying from the Ocean Odyssey
launch platform. The launch occurred at 23:34:55 GMT on 15 February 2006, leaving Echostar X in a geosynchronous transfer orbit. Its orbit was then raised using an onboard LEROS-1C apogee motor, with insertion into geostationary orbit occurring at 20:50 GMT on 22 February.
