Third GGOS Unified Analysis Workshop

ETH Centre main building, Zuerich, Switzerland, 16 - 17 September 2011

The detailed programme including presentations and Action Items is available.

Workshop Scope, Goals, Participation and Sessions:

An important goal of GGOS is to advance the combination and integration of the various space and in-situ geodetic techniques. This goal can only be achieved with the help of all the IAG Services, and especially the IERS and IGFS.
Even if considerable progress has been made in the effort to rigorously combine the various space geodetic techniques (e.g. with the realization of ITRF2008, making use of a new approach based on time series of weekly/session SINEX files), there are still many deficiencies (missing parameters), inconsistencies and systematic effects to be addressed.

The workshop is intended to be a forum for the exchange of information and results concerning both,

  • problems common to more than one service and
  • problems specific to an individual service

For a successful combination of the space geodetic techniques, experts of a certain technique have to be familiar with the critical issues of the other techniques. Therefore, the workshop should increase the common understanding of the individual techniques as they contribute to GGOS.

As in the case of the Unified Analysis Workshop (UAW) of 2007 and 2009, the participation in the UAW 2011 is based on invitation, i.e., the Services decide on the persons to represent them during the workshop (group photo 1, group photo 2).

The workshop is organized in the following four sessions:

  • Session 1: Products by the Services, Filling the GGOS Portal
  • Session 2: Modeling Based on External Data (Atmosphere, Ocean, ...), Modeling Deficiencies and Standards
  • Session 3: ITRF 20xx and Other Combined Products
  • Session 4: Co-location on Ground and in Space, GGOS Core Sites
