PLEASE NOTE THAT DUE TO THE LIMITED NUMBER OF PARTICIPANTS THE FINAL 
REGISTRATION IS REQUIRED.
 
ONLY COLLEAGUES WHO SEND IN THE FINAL REGISTRATION FORM WILL GET A 
CONFIRMATION FOR THE PARTICIPATION IN THE WORKSHOP. 



BACKGROUND

The main goal of the workshop will be the improvement of all the various
IERS products in accuracy, consistency, stability, timeliness, 
user-friendly access, and documentation, to make first steps towards a 
rigorous combination of the various products and thus to contribute 
significantly to the realization of an "International Global Geodetic 
Observation System" (IGGOS). It should therefore involve all the major 
components of the IERS. 

The workshop will be divided into two strongly related parts: the first two
days of the workshop will cover the different aspects of the comparison and
combination of the results of all major space geodetic techniques and the
following two days will focus on the IERS Global Geophysical Fluids Centre
(GGFC), the present status of its products as well as its role in future.

GENERAL INFORMATION

For the efficiency of the Workshop, the programme includes only invited
contributions and discussion. No oral contributed presentations will be
accepted and contributed papers are only posters.

For each of the major topics (sessions) a position paper will be written by
the session conveners and made available before the workshop. It will 
contain the present status, the future requirements, and recommendations
and schedules on how to realize the envisaged goals. 

Participation in the workshop is free (no conference fee).
