Training Process for GALILEO Control Centers: the Multi-level Approach (1)

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

Lessons Learned and Advancements (1)

Derived from real operations having an impact on the definition and Configuration of future IOV and FOC simulations:

Multi-control-centers operations concept Constellation flight operations concept Automation for constellation operations Inter-control-centers constellation simulations

Lessons Learned and Advancements (2) Example of timeline of 4-spacecrafts constellation parallel flight operations:

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 merged simulation concept

Joint inter-control-centers constellation simulations make simulations much more realistic and advanced

Automated command sequence generation approach makes the preparation of simulations much more time- and cost-effective
