EchoStar II is a communications satellite operated by EchoStar. Launched in 1996 it was operated in geostationary orbit at a longitude of 148 degrees west for 12 or 15 years.


The launch of EchoStar I made use of an Ariane 4 rocket flying from Guiana Space Centre in Kourou, French Guiana. The launch took place at 00:59 UTC on September 11, 1996,[2] with the spacecraft entering a geosynchronous transfer orbit. The spacecraft carried 16 Ku band transponders to enable direct broadcast communications and television channels through 0.5 meter dishes on the ground in the Contiguous United States.[3]

From September 1996 to November 2001, it was at position 118.8° W, while from December 2001 until July 2008, it was at position 148° W. The satellite ended its activities on July 14, 2008.
