[IGSMAIL-8303] IUGG2023 IAG G01 Reference Systems and Frames - Session

[Susanne Glaser]

Dear colleagues,

This is a friendly reminder to submit your abstract to session G01 
"Reference Systems and Frames" within the International Association of 
Geodesy (IAG) Symposia of the 28th General Assembly of the International 
Union of Geodesy and Geophysics (IUGG), which will take place from 11-20 
July 2023 in Berlin: https://www.iugg2023berlin.org/

*The abstract submission deadline is **on February 14, 2023.*

Session G01 covers various topics including terrestrial and celestial 
reference frames as well as their geodetic applications. Please find 
below the session description, also available here: 
https://www.iugg2023berlin.org/iag/#top

We are very much looking forward to your contribution and meeting you in 
Berlin!

Best regards,

Susanne Glaser,
On behalf of the conveners Christopher Kotsakis, Geoff Blewitt, Johannes 
Boehm, and Xavier Collilieux

*/G01 Reference Systems and Frames  /*

Reference systems and frames are of primary importance for scientific 
research, satellite navigation, and geospatial applications. A precisely 
defined and accurate reference frame improves our understanding of the 
Earth’s system and its time variations, including Earth’s variable 
rotation and gravity field, sea level changes and their global 
environmental impact, tectonic plate motion, glacial isostatic 
adjustment, geocenter motion, deformation due to the earthquake cycle, 
terrestrial water storage, ice-sheet melting, ocean and atmospheric 
loading, and volcanism.  An accurate reference frame is also needed to 
position GNSS, SLR and DORIS satellites, and any Earth observation 
satellite or aircraft with geodetic sensors such as those used for ocean 
and ice-sheet altimetry, InSAR, gravimetry, and LiDAR. Furthermore, 
self-consistency is required to connect the terrestrial frame, celestial 
frame, and Earth rotation to realize the inherent stability in 
orientation and scale provided by VLBI quasar observations. Co-location, 
whether it be on the ground or in space as planned with VLBI 
transmitters on satellites, is essential to tie the various space 
geodetic techniques together into one consistent global reference system 
to be used for Earth monitoring. For this symposium, we solicit 
presentations dealing with theoretical aspects of reference systems and 
the practical realization of the celestial, global and regional 
terrestrial reference frames, as well as their various applications like 
those mentioned above, and beyond. The contributing role of space 
geodetic techniques in the realization of the origin and scale of global 
frames through new and improved modeling of their systematic errors and 
novel exploitations of LEO satellites is also a topic of great interest 
for this symposium. We also solicit presentations on new and emerging 
technologies applicable to the future of reference frames such as 
inter-satellite links, as well as relativistic and quantum geodetic 
sensors.
