Space Geodesy techniques, such as VLBI, LLR, SLR, GPS and DORIS, 
provide accurate observations allowing to study a wide variety of 
geophysical and geodynamic processes affecting the Earth shape and 
the parameters of its rotation. Based on the analysis of these 
observations, the challenge of this symposium is to discuss the link 
between the three major themes given in the title, highlighting their 
mutual interactions. Topics related to Earth's rotation and reference 
frame correlation and consistency include their common modelling and 
the role of systematic errors, as determined either by an individual 
or multi-techniques of Space Geodesy or combination of individual 
estimates. Of interest to interactions between Terrestrial Reference 
Frame and geodynamics are geodetic and/or geologic global plate motion 
models, Earth surface deformation and geocenter motion. Discussion 
of geodynamic processes that influence the rotation of the Earth 
should focus on effects related, e.g., to core and mantle dynamics, 
including post-glacial rebound and seismic effects.
