Participants can discuss concerns not only related to the contributing technique services, but also all ITRF uses, ranging from local, regional to global applications. Contributions are sought from the individual technique services and various ITRF users, covering the complete range of topics, such as data analysis, parameter estimation and correction models. Of special interest is the assessment of the impact of non-linear station motions, e.g. periodic signals and post-seismic deformations. Contributions by the technique services related to the preparation for ITRF2020 focusing especially on identifying and mitigating technique systematic errors are highly appreciated. Contributions on local tie survey methodology are also welcome. NOTE THAT THE DEADLINE TO SUBMIT EGU2021 ABSTRACTS HAS BEEN EXTENDED TO WEDNESDAY, 20 JANUARY AT 13:00 CET Best regards, Kristel Chanard On behalf of the G.2.2 conveners, Claudio Abbondanza, Mathis Bloßfeld et Susanne Glaser.
