Dear colleagues-

A first IDS weekly combined sol= ution=20 series has been produced as a DORIS contribution to the ITRF2008 call for= =20 participation.  From now, it is limited to the period 2003-2008 = ; but=20 it will be extended up to 1993 soon. The present combination is based on = the=20 contributions of six analysis centers - GOP (Geodetic Observatory Pecny);= =20 INASAN (Institute for Astronomy Russian Academy of Sciences); LCA; IGN; G= AU=20 (Geoscience Australia), and ESA (European Space Operations=20 Center).  

The Combination SINEX files are available=20 at:
ftp= ://ftp.cls.fr/pub/ids/combinations/ITRF2008-IDS/comb_snx/ 

= A=20 very preliminary cumulative IDS solution has been generated by stacking a= ll=20 the combined solutions where WRMS, origin and scale time series WRT ITRF2= 005=20 are shown in the following plot:

= We=20 remind the DORIS Analysts that the next IDS AWG is planned in Paris on Ma= rch=20 23-24, 2009. At this meeting we will review the progress on the contribut= ions=20 of the analysis centers, the status of the IDS combination, and consider = among=20 other topics in particular the  abrupt change  in the scale of = the=20 IDS combination with respect to ITRF2005 in late=20 2004.
