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

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
