Training process for GALILEO Control Centers:
a multi-level approach
Why do we need a flexible training & certification process?
Systems validation
Personnel training
Qualification and certification
Changing resource constraints
Individual system knowledge
Changing training methods
Individual operational skills
Changing training needs
Cross- and re-certification
Operational products validation

Some Lessons Learned and Simulation Advancements
derived from real operations having an impact on the definition
and Configuration of future IOV and FOC simulations:
Multi-control-center operations concept
Constellation flight operations concept
Automation for constellation operations
Inter-control-center communication

Conclusions and Outlook
GCC training process accounts for the evolving training needs and resource constraints
Training relies on highly skilled and experienced trainers and training
Combining purely training- and certification-based with
validation-based simulations as a merged simulation concept
Timeline for the advanced inter-control-centre simulation
makes simulations much more realistic and advanced
Automated command sequence generation approach makes the
preparation of simulations much more time- and cost-effective
Clear communication rules will optimize inter-control-centre
communication during joint simulations and operations
