Fundamental to many demanding Earth science applications,
precise orbit determination, terrestrial positioning and
geo-referencing is the availability of a truly global
terrestrial reference frame (TRF) that only space geodesy is
able to provide. The session solicits contributions covering
the complete range of topics, including conceptual definitions,
improved methods to realize TRFs by individual techniques,
single- and multi-technique combination methods, and better
TRF utilization for applications in geosciences. Of special
interest to the session are papers dealing with data analysis
of space geodesy techniques, including correction models and
parameter estimation, identifying and mitigating systematic
errors, and quantifying their impact on TRF accuracy.
The goal should be attaining 1 mm long-term accuracy and
0.1 mm/yr stability.
