This session welcomes contributions that develop strategies to overcome systematics in space geodetic observing systems such as long-term mean range biases in SLR observations, gravitational deformation of VLBI antennas, GNSS phase center variations, local tie discrepancies in global TRF solutions, etc. This session also focuses on the handling of time in geodesy, delay-compensated time and frequency distribution, time transfer (via space-based atomic clocks and common ground clocks), systematic errors in measurement electronics, optical clocks and quantum sensing for geodetic applications. The integration of optical clocks in Geodesy provides novel opportunities and new challenges, while satellite missions like ACES provide the means to transfer time at unprecedented levels of accuracy.
The second objective of this session is to bring together contributions from individual technique services, space geodetic data analysts, ITRS combination centres and ITRF users, with a broad range of applications from geosciences to society, to discuss the results and scientific applications of ITRF2020 and other realizations. The determination of new local tie vectors at co-location sites, the assessment of observed non-linear station motions, including geocentre motion, through space geodetic techniques by comparison with physics-based deformation models is of particular interest. Furthermore, the handling of co-located instruments of individual techniques onboard satellite missions (space ties) for TRF realization is explored. In general, presentations evaluating the terrestrial reference frame, on new or improved combination strategies, or regarding any type of development that potentially improves future ITRF solutions are highly encouraged.
