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.
