Dear colleagues,

as the abstract submission deadline for the coming EGU GA2020 is 
approaching (Jan 15, 2020, 13:00 CET), we want to draw your attention to 
the session G2.4 on "*New strategies for consistent geodetic products 
and improved Earth system parameters*". The GA will be held in Vienna, 
Austria on May 03-08, 2020.


Please find below the detailed session description:

The geodetic products that describe the system Earth are of high 
quality, although the Global Geodetic Observing System (GGOS) goals of 1 
mm accuracy and 0.1 mm/yr stability for the terrestrial reference frame, 
the Earth Orientation Parameters (EOPs) and the static and time-variable 
gravity field of the Earth are not yet fully reached. There are limiting 
factors that need to be detected, analyzed, and quantified. In this 
context, the usage of a sub-set of available observations only, 
degrading station equipment quality, limitations in the observing 
concepts and analysis and combination methods evoke the question whether 
and how the derived Earth system products can be improved.

In principle, there are two ways to investigate the best methods for 
improving geodetic products:

(A) New strategies of handling, analyzing and combining the already 
existing space-geodetic observations need to be developed.

(B) The existing observing infrastructure should be extended by new 
stations, new satellite missions, and new types of observations or new 
observing concepts.

In the latter case, simulation studies are indispensable.

This session provides a platform for presentations of new strategies, 
new analysis methods and simulation studies seeking to improve the 
determination of Earth system parameters and geodetic products such as 
the Terrestrial and Celestial Reference Frame (TRF, CRF), EOPs, Earth’s 
gravity field, satellite orbits, as well as atmospheric key parameters. 
Presentations investigating approaches for reaching a better consistency 
between the individual parameters are highly welcomed, e.g., studies 
towards consistent estimation of the TRF, CRF and EOPs. Concerning 
consistency, novel approaches to achieve a consistent estimation of the 
three pillars of geodesy, i.e., geometry, orientation and gravity, are 
also welcomed. In addition we are seeking contributions focusing on 
alternative analysis concepts such as employing co-locations in space, 
clock ties, or atmospheric ties. Simulation studies investigating 
dedicated co-location satellites or novel observation methods (e.g. 
inter-satellite links or VLBI tracking of GNSS satellites) and their 
potential for improving the geodetic parameters are also invited. Many 
of the aspects mentioned above are brought together within the GGOS 
Standing Committee PLATO (Performance Simulations and Architectural 
Trade-Offs). Therefore, contributions related to the activities carried 
out within this group are also appreciated.

Please consider submitting an abstract to this session on consistent 
geodetic products. We are looking forward to your contribution.

On behalf of the convenors of session G2.4,
Mathis Bloßfeld
