Syracuse is the name of a program for military communication satellites operated by the French space agency CNES .

Satellites

From 1980 to 2005, nine geostationary satellites named Syracuse I and Telecom 1A, 1B, 1C, 2A, 2B, 2C, 2D and Syracuse IIIA were launched into space. The takeoff weight increased from 0.7 t for Syracuse I to 3.72 t for Syracuse IIIA .

The Syracuse III satellites are based on the Spacebus 4000 B3 satellite platform and are produced by Alcatel Alenia Space .

On August 12, 2006 at 00:15 CEST from Center Spatial Guyanais in Kourou , French Guiana , another satellite in the series called Syracuse IIIB was launched into space at the tip of an Ariane 5 launcher. It weighs 3750 kilograms and is worth around € 2.3 billion. It has nine SHF and six EHF channels and can simultaneously communicate with up to 600 ground stations between the eastern United States and eastern China. It was stationed at 5 degrees west and is designed for a lifespan of 12 years.
