Subject:[SLR-Mail] No.2824: EGU24, Session G2.1: Precise Orbit Determination for Geodesy and Earth Science
Author:unknown
Content:Dear colleagues,

we would like to draw your attention to the session G2.1 Precise Orbit
Determination for Geodesy and Earth Science organized at the upcoming
General Assembly of the European Geosciences Union, taking place from
April 14-19, 2024. The EGU24 aims to bring together geoscientists from
all over the world to one meeting covering all disciplines of the Earth,
planetary, and space sciences. The EGU aims to provide a forum where
scientists, especially early career researchers, can present their work
and discuss their ideas with experts in all fields of geoscience.

G2.1 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. Four constellations of GNSS satellites are
available and numerous position-critical missions (e.g. altimetry,
gravity, SAR and SLR missions) are currently in orbit. Altogether,
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 from, 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; (10)
simulation studies for the planned co-location of geodetic techniques in
space mission GENESIS.

Please consider submitting an abstract to this dedicated orbit session.
The deadline for abstract submission is January 10, 2024 at 13:00 CET.
We are looking forward to your contribution.

On behalf of the convenors of session G2.1,
Adrian Jggi

Co-conveners: Alexandre Couhert, Jose van den IJssel, Oliver
Montenbruck, Urs Hugentobler
