Initial Operations Ramp-up

• Start of EGNOS operations
• by the ESSP Operation Consortium
• Increase of staff and resources to fully support
  EGNOS operations
• Facilitate the transfer of knowledge and
  experience from ESA / Industry to Operator
• Test the operations processes and procedures
• Deliver remaining training packages to build up
  team capabilities

8
Initial Operations Stabilization

• Reach nominal EGNOS operations performance
  (started on April 3rd 2006)
• Stabilise team resource profiles, to support
  EGNOS operations according to the operations
  performance requirements
• Run nominal maintenance procedures across the
  EGNOS system
• Complete operations processes and procedure
  testing

9
Initial Operations Qualification

• Operational qualification of EGNOS system
  operations
• Demonstrate that EGNOS operations staff, plus
  procedures and documentation, can support EGNOS
  operations performances
• Provide evidence towards the EGNOS System Safety
  Case with nominal operations
• Concludes with the Operations Qualification
  Review (OQR) in early 2007
• Safety of Life service provision planned to
  follow this milestone
