"Earth rotation, reference systems and celestial mechanics:

Synergies of geodesy and astronomy"

(Poster of the Journées 2011)



The Journées 2011 "Systèmes de référence spatio-temporels" with the sub-title "Earth rotation, reference systems and celestial mechanics: Synergies of geodesy and astronomy" will be held at Bundesamt für Eich- und Vermessungswesen (BEV), Vienna, from 19 to 21 September 2011.


Scientific Objectives

The Journées 2011 will be the 21st meeting in the Journées conference series (see Previous Journées), which provide a international forum for advanced discussion in the fields of space and time reference systems, Earth rotation, dynamics of the solar system, astrometry and time. The Journées 2011 will be focused on issues related to recent developments in fundamental astronomy, time and relativity, plans for the next generation of space-time reference systems, astronomical space and time reference systems, Earth rotation and global geodynamics, celestial mechanics of solar system bodies, space observations and dedicated missions for geodesy and astronomy.
There will be presentations and discussions related to the Division 1 IAU Working Groups, or Division 1 commissions.


The Journées 2011 are co-sponsored by the International Astronomical Union (IAU)
and the International Association of Geodesy (IAG).



Preliminary programme:

  • Session 1 - Fundamental astronomy, time and relativity
  • Session 2 - Towards the next generation of space-time reference systems
  • Session 3 - Modelling, observation and prediction of Earth rotation and global geodynamics
  • Session 4 - Celestial mechanics of solar system bodies
  • Session 5 - Space observations and dedicated missions for geodesy and astronomy
  • Discussion - On future IAU recommendations and organization
