Your contributions to this session are very welcome. The session 
description is given below.

With best regards,

GS005:  The Global Geodetic Observing System
Sponsoring Association: IAG

The helplessness felt in the wake of recent natural disasters (the 
tsunami in the Indian Ocean, flooding in New Orleans, etc.) has made it 
abundantly clear that our understanding of the complex Earth system and 
our tools for the timely detection of potentially disastrous events are 
rather limited. Therefore, gaining deeper insights into the processes 
and interactions of this system is one of the most urgent challenges 
facing society. Earth observation is fundamental for advancing our 
understanding, and a global Earth monitoring system is high on the 
agenda of a large number of countries.
The Global Geodetic Observing System (GGOS) has been set up by the 
International Association of Geodesy (IAG) as the geodetic contribution 
to such a global Earth monitoring system providing, in particular, the 
metrological and reference system basis for all Earth observing systems. 
GGOS represents an umbrella for the products derived by the IAG Services 
using the space geodetic techniques (VLBI, SLR/LLR, GNSS, DORIS), 
altimetry, InSAR, gravity missions, and in-situ measurements etc. 
allowing for the monitoring of the Earth system with an unprecedented 
accuracy of less than one part in one billion.
This session will focus on all major issues concerning GGOS: 
contributions are very welcome dealing with the design of a future GGOS 
(networks, communications, data portals, innovative observation 
technologies and analysis methods, new satellite missions, early warning 
systems, ), the combination of different space- and ground-based 
geodetic observation techniques including  common modeling and 
parameterization standards for all techniques, the integration of models 
for Earths  deformation, variations in Earths rotation and temporal 
changes in the gravity field, the study of mass transport phenomena in 
the Earth system and their observation and modeling, and the progress 
being made by the IAG services towards GGOS.
