This document discusses the training and simulation process for the Galileo Constellation Operations conducted by DLR Gesellschaft für Raumfahrtanwendungen (GfR) mbH. It outlines the multi-level training approach used for the Galileo control centers, including standalone and joint simulations. It describes how simulations have evolved from early campaigns involving 2 satellites to future campaigns planned for a full 27 satellite constellation. Lessons learned from simulations and operations are applied to continually advance the training process to meet the needs of a large, operational satellite navigation system.

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

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
