Country of origin United States
Mission Telecommunications
Geostationary orbit see below
Launch vehicle Atlas 5 #4

Hybrid Ku- & Ka-band satellites, maybe using slots reserved for GE Star.

Suffers some power loss on solar array circuits which have reduced capacity. In Mar 2010 some transponders had to be switched off. Another failure occured in Jan 2012, Apr 2012, Nov 2012. Each event reduced the satellite's capacity.

In 2015, the company is pending authorization to repoint the Ku-band antenna to South America.
