� Conclusion


� Arianespace is a European company:

– Shareholders include CNES and 20 space companies representing 10European countries

– Convention with the European Space Agency (ESA)

– Launches are performed at the Guiana Space Center (CSG)

� Three launch systems operating at CSG:

– The heavy-lift Ariane 5

– The mid-size Soyuz (also launched from Baikonur with Starsem)

– The light-weight Vega

� For over 30 years, Arianespace has been the world reference inlaunching satellites for science, Earth monitoring, security andcommunications applications

=> The European Access to space

Arianespace Identity Card (1/3)


� Through Arianespace, Europe demonstrates its technicalexpertise based on the heritage of:

– 212 Ariane launches

– 30 Soyuz launches (4 at CSG and 26 at Baikonur with Starsem)

– 2 Vega launches

� Operating the launch vehicle family and relying on the benefitsof Guiana Space Center (CSG), Arianespace offers:

– Services for European institutions

– Customized low-risk solutions for all customers

� From contract signature to in-orbit delivery, Arianespaceprovides turn-key service with the highest standard ofcustomer care:

– Highly-skilled teams ensure efficient risks mitigation processes andsmooth operations

– Flawless quality assurance with unique transparency

– Very accurate orbit insertion

– Value-added options for financing and insurance

=> A Premium Service



� A consistent and standard approach for the 3 Launch Vehicles:

– Improve quality and efficiency thanks to each other launchers cross experience

– Allow possibility of launch service back-up

– Simplify customer life

� Implementation of a unique approach for the whole family:

– Simplified industrial chain with a Prime Contractor for each Launch Vehicle, in development and in production

– Qualification Authority during the development phase involved as Independent Technical Authority during the production phase

– Payload Preparation Facilities (PPF) management, flight safety, security and launch base support under CNES responsibility

Three launch systems, one unique approach

=> A Success-Proven organization which mitigate the risks



European dedicated, state-of-the-art launch facilities

– Common facilities for the 3 Launch Systems

– Western standards, all required security levels

– Modern, efficient and operational facilities

� France adopted on June 3rd 2008 the French Space Operations Act (FSOA).

� The general purpose is to set up a coherent national regime of authorization and control of space operations under the French jurisdiction.

� The FSOA and associated regulations are in force since December 10th 2010.

The French Legislative Framework (1/3)

=> The FSOA is directly applicable to Arianespace


� Since December 2010, Arianespace is subject to FSOA framework and liability andis declared as Launch service operator.

� For each launch, Arianespace submit the necessary set of files which demonstratethe fulfillment of the technical regulation either in a generic or in a specific way.In particular:

– A generic demonstration of the conformity of the launch system at the state of the qualification.

• Description and domain of use

• Hazards study

• Environmental impact study

• Risks management plans

– A detailed description of the operator’s organisation confirms the sustainability of the processes deployed and used by the operator in order to master the risks.

– A detailed description of the mission, including the dedicated specimen of launch vehicle and the spacecraft’s characteristics. If any, additional specific risks mitigation measures would be detailed at this step.


⇒ For each launch, the compliance to the FSOA and regulations must be demonstrated


� With present launch systems, the qualified domain covers, in particular, thefollowing risks mitigation measures :

– Clean separation systems for stages

– Orbital procedures designed to ensure accurate separation of entities and each other minimum distances

– Perigee constraints designed to minimise in-orbit dwell time

– Procedures for the passivation of stages remaining in orbit

– Controlled upper stage re-entry strategies where this is possible

� In addition, mission analyses studies detail:

– Trajectory optimization for minimization of hazard at fall down or reentry.

– Short range hazard mitigation through trajectory corridors, ground and altitude wind limitations.

– Long range Atlantic Ocean drop zones determination and constraints.

– Long range cumulative risk minimization within legal criteria thresholds.

– Inhabited orbiting object collision risk avoidance measures

– Planetary protection measures where this risk exists


=> Arianespace applies risks mitigation measures

For Arianespace: “Safety is not an option”

Arianespace positioning on the global market is based on:

� A stable shareholding structure;

� Over 30 years of experience launching satellites for operators and agencies from all around the world;

� An experienced world class operational team and a state of the art launch base;

� A robust capacity in monitoring launchers quality for the highest reliability;

� The application, on ground and in flight, of risks mitigation measures induced by return on experience and legal framework.

Conclusion

⇒ These practices contribute to preserve an operational culture of safety and reliability in our activities
