                 BASIC CONCEPTS
The proposed ground segment for the WSO/UV has been defined as a
  fully distributed architecture composed of modular layers:

• Each layer contains components with identical functionality
  providing a concrete added value to the next layer in the hierarchy.
• The principles behind this layered architecture are very similar to the
  Open Systems Interconnection Reference Model.

The layered design of the ground segment is the concrete form of
  implementing the international collaboration. According to this
  guideline, each layer shares architecture, technology, operational
  procedures and knowledge to provide homogeneous services to the
  next layer in the model.

Ground station layer: Comprises the
   network of primary and backup
   ground stations.

Control centre layer: Includes the
  control centres co-located with a
  ground station, under the
  coordination of the mission control
  centre.

Science centre layer: Comprises the
   science operations centre and the
   different national/regional science
   centres.

End user layer: The science users.

               SOME QUESTIONS:
• Do you agree with these work packages?
• Which is the minimum antenna set-up and the
  participants in the ground segment?, do they agree to go
  through qualification tests (and pay for them)?
• Distributed MOC with a Russian prime?, only Russian
  MOC from launch until nominal orbit reached?
• How are Russian, Chinese and Spanish technologies
  interact?
• What about SOC?, Instruments SOCs?

• Could we agree in a common phase A/B study?
