| Content: | Dear colleagues, We would like to draw your attention to the session G2.4 Precise Orbit Determination for Geodesy and Earth Science organized at the upcoming General Assembly of the European Geosciences Union in Vienna, Austria, April 07 12, 2019. Session description: Precise orbit determination is of central importance for many applications of geodesy and earth science. The challenge is to determine satellite orbits in an absolute sense at the centimeter or even sub-centimeter level, and at the millimeter or even sub-millimeter level in a relative sense. New constellations of GNSS satellites are currently being completed and numerous position-critical missions (e.g. altimetry, gravity, SAR and SLR missions) are currently in orbit. All together outstanding data are available offering new opportunities to push orbit determination to the limit and to explore new applications. This session aims to make accessible the technical challenges of orbit determination and modelling to the wider community and to quantify the nature of the impact of dynamics errors on the various applications. Contributions are solicited but not limited to the following areas: (1) precise orbit determination and validation; (2) satellite surface force modelling; (3) advances in modelling atmospheric density and in atmospheric gravity; (4) advances in modelling earth radiation fluxes and their interaction with space vehicles; (5) analysis of changes in geodetic parameters/earth models resulting from improved force modelling/orbit determination methods; (6) improvements in observable modelling for all tracking systems, e.g. SLR, DORIS, GNSS and their impact on orbit determination; (7) advances in combining the different tracking systems for orbit determination; (8) the impact of improved clock modelling methods/space clocks on precise orbit determination; (9) advances in modelling satellite attitude. Please consider submitting an abstract to this dedicated orbit session. The deadline for abstract submission is January 10, 2019 at 13:00 CET. We are looking forward to your contribution. Note that the session G2.4 will also participate in the peer-reviewed joint proceedings of the geodesy division that will be published in the EGU open-access journal Advances in Geosciences (see https://www.advances-in-geosciences.net/).
