Description:	Over the past half-century, space-geodetic technologies  
have changed completely the way we look at the planet, not only in  
terms of exquisite details and accuracy, but also in terms of how the  
entire planet changes with time, even on “human” time scales. The  
remarkable achievements of Earth observing missions over the past two  
decades, and the success of future international missions described in  
the Decadal Survey depend both implicitly and explicitly on the  
continued availability and enhancement of a reliable and resilient  
global infrastructure for precise geodesy, and on ongoing advances in  
geodetic science that are linked to it. This allows us to deal with  
global scientific, technological and social issues such as climate  
change and natural hazards, but the impact of the global precise  
geodetic infrastructure also permeates our everyday lives. This  
session seeks papers that touch on the fundamental geodetic science  
associated with this infrastructure— from reference frame to time- 
dependent geoid, from tectonics to general reltivity, and from  
navigation to global change. We will also welcome reviews that  
highlight how most Earth observing missions could not achieve their  
scientific goals without such global infrastructure (especially  
alitmetric missions). Of great interest would be illustrations of how  
precise geodesy has successfully achieved the transition from arcane  
fundamental science and engineering to everyday applications, which  
most of us take for granted. Finally, forward-looking presentations  
describing ongoing scientific research, as well as future capabilities  
will be especially welcome.
