8 Page : 8/24 Ed.: 1 Rév.: 0 Date :11/02/ PRINCIPAL MISSIONS VEGA Launch Site (SLV), ICPE classified site, is a compound dedicated to perform VEGA launch campaign operations: - transport and storage of launcher components (P80, P23, P9, AVUM and payload), - final integration and acceptance of the launcher 1st stage (P80), - preparation and integration of the payload on the launcher, - integration and verification of the launcher. Ariane Launch Base is also involved to provide general and specific supports including: - telemetry and radar tracking of the launcher in flight, - post-launch flight data analysis.

9 Page : 9/24 Ed.: 1 Rév.: 0 Date :11/02/ GENERAL OPERATIONAL REQUIREMENTS AND CONSTRAINTS The VEGA ground segment must be operational for an initial launch scheduled for mid 2006: - rate = 4 launches per year for at least 10 years, - inter-launch interval = minimum 1 month, - launch campaign = 10 to 11 days, - final preparation phase and countdown = max. 1 day, - number of countdown over 3 consecutive days = 3, - standardisation of equipment with that of other ELA sites must be taken into account for optimised synergy with operating teams and spares, - availability requirements: ground segment launch probability factors are : 82.8% at H0, 10.2% after H0, 6.5% for J1, 0.5% after J Operational requirements for chronology - countdown duration = < 2 hours (TBC), - reference launch window = 3 hours (TBC), - synchronised sequence duration = < 5 min (TBC). If the synchronised sequence is stopped, the systems are returned to the "Synchro ready" state, ready for restart at the beginning of a new synchronised sequence, - number of synchronised sequences per countdown = 5, - countdown breakdown: ground segment and launcher preparation phase, "synchro ready" phase, during which the ground and On Board systems are ready and waiting for the synchronised sequence, synchronised sequence phases, comprising final pre-launch operations, confirming launcher readiness on the ground and referenced to time H0, ignition/lift-off phase, - it must be possible to stop the launch safely at any time before H0.

10 Page : 10/24 Ed.: 1 Rév.: 0 Date :11/02/ Operational requirements and constraints with respect to A5 The design of ground and on board systems must provide minimised operational constraints between AR5 and VEGA campaigns during VEGA countdowns. The design of ground and on board systems should not lead to operational constraints outside countdown rehearsals with the BLA, launch countdown (for which links with the BLA are configured) and stage transfers. Ground checkout equipments must be independent from the ELA3 ones (apart from utility services). The delay required for configuration of links with the BLA and associated verifications shall be minimised. Ariane 5 transport and handling facilities (apart from the gantry travelling crane) of the CSG shall be reused for VEGA Operational requirements with respect to Pay Loads Mission change: at least 2 months (TBC) before the launch date. Operational constraints between the launcher and payload campaigns must be reduced to the minimum. The design of ground and OB systems shall allow integration of the payload at the latest possible stage of the launch campaign, so as to meet the requirement of launching a payload at TBD days notice. If the countdown is stopped at the end of the launch window on launch day J0, it must be possible to execute a fresh countdown the following day (J1). Intervention time on the launcher between two successive countdowns: max. 18 hours (TBC). Access to the launcher and payload in the ZLV requires the rollback of the gantry.

Ground Segment cost related design constraints To reduce recurrent and development costs, existing facilities will be adapted: - the launch zone will be the ELA1 and the control room will be the CDL3, - the Vega Launch Site will use Ariane Launch Base facilities (telecommunications, energy supply, fluids, gases, water and the access road system, etc.), - Ariane 5 telemetry, ground stations,radars and safety facilities will be reused for VEGA, - the upper composite (S/C, adapter, fairing) will be integrated in the EPCU S3, - existing facilities will be used for launch campaign support purposes (BT, BGQ, COPA, restaurants, etc.), - small pyrotechnic equipment will be prepared in existing facilities (pyro laboratory ), - launcher batteries will be prepared in existing facilities, - the P23 and P9 stages will be stored in the existing pyrotechnic zone, and other Ariane storage zones will be reused if necessary Ground Segment technical design constraints - the P80 will be transferred from the BIP to the SLV by road in the vertical position, - the launcher will be assembled on the bunker in the vertical position, - the launch zone will incorporate a mobile gantry (air-conditioned) with its rail track, a fixed launch table referred to as the "bunker", an umbilical mast and existing flame chutes adapted as necessary to meet acoustic requirements, - the umbilical mast must support and protect the launcher and payload ventilation system, communication links between the launcher and payload and their respective ground checkout equipment, and the umbilical disconnection system from atmospheric conditions and launch effects, and must be air-tight and pressurised, - the P80 stage will be stored in its production zone or in the gantry (this storage function is not a (Vega) ground segment responsibility) Ground Segment general design constraints Validation of the SLV, including degraded modes, software and procedures, will be carried out on mock-ups of the launcher and simulators, at least for electrical, mechanical and fluids equipment, prior to the first launch campaign. The Ground Segment must take into account the Launch Vehicle growth potential. Vega ground segment development costs must be kept to a minimum by using Ariane 5 systems when applicable, or by reusing available studies and models. Constraints induced on Ariane 5 operations will be kept to a minimum during the development and production phases. The facilities must withstand climatic conditions encountered in French Guyana, as also launch effects. Discharges and effluents will be processed in accordance with applicable laws and regulations.

The existing Services control system. CCS will be modified to integrate dedicated VEGA functions. The CCS must provide the same functions as defined for Ariane and will use the same technology: - fire detection and extinction for all premises, - monitoring of Cat. I, II and III energy, - air conditioning, - optics, - toxic vapor detection, - O2 shortage detection, - monitoring of valve positions, etc.
