This is an ORAL session. The quantification of many geophysical phenomena, e.g. sea level variation, co-and post-seismic deformation, glacial isostatic adjustment, loading effects, but also precise orbit determination of artificial satellites, rely on the availability of a global terrestrial reference frame, such as the ITRF.

This ORAL session solicits presentations on scientific applications enabled by IGS products and new science enabled by improvements to quality and breadth of GNSS products.
