Eutelsat, S.A. ordered its first satellite from Satellite Development Center in February 2001. The satellite, e-BIRDTM, is a Boeing 376HP spin stabilized model.

e-BIRDTM offers capacity optimized for high-speed access networks providing both forward and return links via satellite. The spacecraft carries 20 active Ku-band transponders, each powered by a 33-watt traveling wave tube amplifier. The Ku-band transponders are connected to four spot beams that will provide coverage over Europe and Turkey.

The spacecraft will operate at 33 degrees East longitude, and has a contract life of 10 years. e-BIRDTM was launched on September 27, 2003 aboard an Ariane 5 rocket.

All Boeing 376 models have two telescoping cylindrical solar panels. These panels and the deployable antennas are stowed for compactness during launch. The highly reliable design makes full use of a nickel-Hydrogen battery during eclipses. The 376 design minimizes the number of required mechanisms and has never had a deployment failure.

Satellite Development Center is the world's leading manufacturer of commercial communications satellites and a major provider of space systems, satellites and payloads for national defense, science and environmental applications.
