Galileo and Operations Entity

• Galileo
• Project founded by the EC and ESA
• First satellite positioning and navigation system
  specifically designed for civil purposes
• Outstanding performance in accuracy, continuity
  and availability
• Space segment
• 30 satellites in three 56 inclined orbits in an
  altitude of approximately 23,000 Km
• Ground segment
• control centers, ground stations and service
  centers in more than 40 sites worldwide
• Operations Entity
• Operate the entire system in an efficient and
  reliable manner
• Contributes to the formal handover activities of
  the system and its operational acceptance

Facilities to be Operated

• Galileo System
• The operations of the systems are concentrated in
  the control centers
• Ground stations are remote controlled
• Control centers will host facilities of the
  Ground Control Segment (GCS) and the Ground
  Mission Segment (GMS)
• Remaining facilities and elements of the segments
  will be installed at the remote sites of the
  ground stations.

GCS
GMS

• GMS in Control Centre
• orbit determination,
• time synchronization
• and integrity processing. - controlled via a
  mission
• control central facility
• facility for centralized
• control of Galileo system

• GCS in Control Centre
• monitor and control

Context of Operational Acceptance

• operational acceptance is rarely used in the
  space mission related documentation
• Classical approach
• operational acceptance and contractual acceptance
  of the ground system is identical
• Operations and procurement of the ground system
  are both under the responsibility of the
  operations provider.
• Galileo approach
• With independent providers for ground system, AIV
  and operations it is necessary to introduce a
  clear definition of the various processes and
  relationships between each
• In principle the issue is Galileo (or system)
  independent
• In general, the problem occurs, wherever a system
  is provided as Customer Furnished Item (CFI) to
  an operations provider
• The operations provider has to rely on the system
  whether his customer has done a good job, when
  verifying and accepting the system

Example Car Renting ? Scenario

• Task
• Transport from A to B
• Prerequisite
• Take a car from a specific car rental company
• The system handed-over as customer furnished item
  shall enable the operations provider to fulfill
  his contractual obligations in the provision of
  operations service.
• When signing the operations contract the system
  is under design and development, the final
  features are not yet known,
• The operations provider will have to assess his
  effort to operate the system without an in depth
  knowledge of the system operational aspects.

The rental car companyprovides a car with the
appropriate functionality
The driver performs a inspection of the car.
The transport will be conducted.

System/Operational Acceptance and Validation

• System Acceptance
• conduction of a formal acceptance test of a
  system which is performed by the customer at the
  operations premises after installation with
  participation of the system supplier
• ensure that the contractual requirements are met
  and to demonstrate the item is free from
  manufacturing defects
• Operational Validation
• ultimate part of the ground segment verification
  process
• whole ground segment including operations
  personnel and its readiness to support the space
  mission in-orbit
• Ground segment is understood as ground facilities
  plus operations personnel
• Operational Acceptance
• The operations provider shall have the
  opportunity to check if the expected
  functionality of the CFIs has been implemented
• ensure that the operations provider is able to
  fulfill his contractual obligation with the
  customer furnished system

Proposed Methodology

• Proposed Option
• Contribution to the system acceptance of the
  system customer
• Dedicated operational acceptance tests for each
  release of the system
• Description
• The operations provider shall be involved in all
  steps of system development
• Requirements definition and consolidation
• Preliminary and critical design reviews
• System, compatibility and acceptance testing
• Verify that the assumptions for the contractual
  obligations are met
• Acceptance tests to be repeated for each release
  of the system
• Result
• Assurance that CFIs are as expected
• OR
• Demonstration that contractual operations
  obligations cannot be fulfilled

Conclusion

• What changes the operations sector if the ground
  systems for operating satellites and the
  processing of payload is a customer furnished
  item for the service provider?
• Operations of Galileo System requires a new task
  in the acceptance process
• The best approach under cost, time and effort
  issues is to combine it with system acceptance
  activities of the customer
• The operational acceptance of a CFI is also
  beneficial for the customer
• Mitigation of system failure risk and operational
  risk.
