[IGSMAIL-7720] Precise Orbit Determination for Geodesy and Earth Science | G2.4 | EGU 2019 | Reminder

[Adrian Jaeggi]

Dear colleagues,

This is just a friendly reminder that the abstract submission deadline 
for the upcoming EGU General Assembly is approaching quickly, i.e., 
Thursday, January 10, 2019 at 13:00 CET. We are looking forward to your 
contribution for the Session G2.4: Precise Orbit Determination for 
Geodesy and Earth Science.

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.

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/).

On behalf of the convenors of session G2.4,

Adrian Jäggi

Co-conveners: Urs Hugentobler, Oliver Montenbruck, Heike Peter, Jose van
