Dear colleagues

A first IDS weekly combined solution series has been produced as a DORIS contribution to the ITRF2008 call for participation.  From now, it is limited to the period 2003-2008  but it will be extended up to 1993 so= on. The present combination is based on the contributions of six analysis cente= rs - GOP (Geodetic Observatory Pecny); INASAN (Institute for Astronomy Russian Academy of Sciences); LCA; IGN; GAU (Geoscience Australia), and ESA (Europe= an Space Operations Center).   

The Combination SINEX files are available at: 
ftp://ftp.cls.fr/pub/ids/combinations/ITRF2008-IDS/comb_snx/&n= bsp; 

A very preliminary cumulative IDS solution has been generated by stacking a= ll the combined solutions where WRMS, origin and scale time series WRT ITRF2005 are shown in the following plot:  http://ftp.cls.fr/pub/ids/combinations/ITRF2008-IDS/comb_snx/t= 7p_comb.gif.<= br>
More information about the IDS ACs participation is available at:
 http://ids.cls.fr/html/analysis_coord/combination/itrf2008.htm= l
We remind the DORIS Analysts that the next IDS AWG is planned in Paris on M= arch 23-24, 2009. At this meeting we will review the progress on the contributio= ns of the analysis centers, the status of the IDS combination, and consider am= ong other topics in particular the  abrupt change  in the scale of the IDS combination with respect to ITRF2005 in late 2004.
