4. GENERAL OPERATIONAL REQUIREMENTS AND CONSTRAINTS
The VEGA ground segment must be operational for an initial launch scheduled for mid 2006:
-
4.1.
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 J1.
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.

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.
4.3.
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.

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.
7.2.
-
-
-
7.3.
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.

11. MODIFICATION OF THE EXISTING FACILITIES
Some facilities used in common with Ariane 5 will not be modified as VEGA size is not critical. These
facilities concern:
-
EPCU (payload preparation complex) for preparation of the upper part,
installations for preparation of the batteries (TBC),
pyrotechnic storage area,
UDMH storage area (rehabilitated for the Storable propellant stage (EPS)),
NTO storage area (created after closure of the ELA2),
low current facilities, transportation.
Installations re-used after the closure of ELA2 may be modified in order to accommodate VEGA.
These installations concern:
-
the BESSEL and KEPLER building for VEGA team dedicated offices,
the assembly hall (HA), refitting according to the storage surface area,
the ZES (TBC), refitting for collection of the sewage,
the solid booster (PAP) storage area, fitting out to be examined for preparation of the
stages,
roadway systems, mainly filling of potholes.
