EchoStar I is a communications satellite operated by EchoStar. Launched in 1995, it was operated in geostationary orbit at a longitude of 77 degrees west for 12 or 15 years. The company has approved the transfer of the 77 degree west orbital position to as of September 22, 2010.
Satellite[]
The launch of EchoStar made use of a Long March rocket flying from Xichang Satellite Launch Center in Sichuan province of the People's Republic of China. The launch took place at 11:50 UTC on December 28, 1995, 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 American continents.[1][2]
