  1 Follow the launch live on the internet broadband at www.arianespace.com (starting 20 minutes before lift-off) Arianespace’s fourth mission of the year will place two communicationssatellites into geostationary transfer orbit: Syracuse 3A for the FrenchMinistry of Defense, and Galaxy 15 for the American satcom operatorPanAmSat. Syracuse 3A is the first satellite in France’s new third-generation Syracuse IIIsystem, dedicated to secure military communications.French defense procurement agency DGA (Délégation Générale pour l’Armement),part of the MoD, is in charge of this program, with management provided by theObservation, Telecommunications and Information Programs Department (SPOTI).Alcatel Alenia Space and Thales Communications are joint prime contractors. TheSyracuse 3A satellite is designed by Alcatel Alenia Space, while ThalesCommunications is in charge of the ground segment, comprising some 600networked ground stations. The satellite will weigh about 3,700 kg at launch.NATO has chosen the Syracuse III system as part of its NATO Satcom Post-2000program. Led by France, in collaboration with the UK’s Skynet system and Italy’sSicral system, this project is designed to pool satellite resources for subsequentsharing with other NATO members. It is the cornerstone in a European militarysatcom system.Galaxy 15, weighing nearly 2,000 kg at liftoff, is the third next generation satellitethat PanAmSat has ordered from Orbital Sciences Corporation to provide greaterflexibility and availability to its customers.The launch of Galaxy 15 is a breakthrough for PanAmSat, carrying a dual C-bandand L-band payload that will cement its leadership position in HDTV and video forcable as well as drive new government-related business. To be located at 133 degreeswest longitude, the satellite is the third of PanAmSat's next-generation satellitesfrom Orbital Sciences Corporation, providing coverage of all 50 U.S. states.Since PAS 1, launched by the first Ariane 4 in June 1988, Galaxy 15 is the 20thPanAmSat satellite to be launched by Arianespace’s family of launch vehicles. 1 - The ARIANESPACE - SYRACUSE 3A/GALAXY 15 mission2 - Range operations campaign: ARIANE 5 - SYRACUSE 3A/GALAXY 153 - Launch countdown and flight events4 - Trajectory5 - The ARIANE 5 launch vehicle6 - The SYRACUSE 3A satellite7 - The GALAXY 15 satelliteAppendix 1.

Launch countdown and flight events The countdown comprises all final preparation steps for the launcher, the satellites and the launch site. If itproceeds as planned, the countdown leads to the ignition of the main stage engine, then the two boosters, fora liftoff at the targeted time, as early as possible in the satellites launch window.The countdown culminates in a synchronized sequence (see appendix 3), which is managed by the controlstation and onboard computers starting at T-7 minutes.If an interruption in the countdown means that T-0 falls outside the launch window, then the launch will bedelayed by one, two or more days, depending on the problem involved, and the solution developed.
