Dear colleagues,


for your information, you can now access the DPOD2000 frame (positions, velocities mostly based on ITRF2000 as well as quality codes for POD uses) at CDDIS.


2 files are provided:


in sinex format 
ftp://cddis.gsfc.nasa.gov/pub/doris/general/dpod/dpod2000_0.snx.Z


in text format
ftp://cddis.gsfc.nasa.gov/pub/doris/general/dpod/dpod2000_0.txt.Z


There is a also a readme file providing more information


ftp://cddis.gsfc.nasa.gov/pub/doris/general/dpod/DPOD2000.README


In the future, we plan to update this file from time to time, when new DORIS stations are added to the permanent tracking network. We would then add a new version number at the end of the file name (eg dpod2000_1.snx.Z) to avoid any confusion.


A complete description of the DPOD2000 reference frame can be found in :


Defining a DORIS core network for Jason-1 precise orbit determination based on ITRF2000, Methods and realization, P. Willis. J.C. Ries, J. Geod., 2005, DOI: 10.1007/s00190-005-0475-9, in press.


Proper reference for citation would be appreciated


Best regards
Pascal Willis and John Ries


NB: we will update the citation in a future DORISMail when we get the final publication information
