Dear colleagues,

For your information, we have derived an extension of ITRF2005, called
DPOD2005 for DORIS Precise Orbit Determination.

For all DORIS stations, coordinates in ITRF2005 at epoch 2000.0 and
velocities are provided. Information on station coordinates and velocity
discontinuities, as well as period during which DORIS data should not be
used are also given. Additional information are also provided on a site by
site basis, explaining how we derived these results:

http://www.ipgp.jussieu.fr/~willis/DPOD2005.htm

We plan to update information on this Web site on a regular basis,
starting with current version 1.1 . So, if you find errors or if you have
any question, please feel free to recontact me at willis at igpg.jussieu.fr

This work was done by a group of people and we will soon submit an article
in Advances in Space Research to document these results, after a
presentation at the next COSPAR meeting in Montreal in July :

P. Willis, J.C. Ries, L. Soudarin, N. Zelensky, E.C. Pavlis, DPOD2005 :
Realization of a DORIS terrestrial reference frame for precise orbit
determination, ADVANCES IN SPACE RESEARCH, in preparation

A similar work was performed in case of ITRF2000, leading to DPOD2000.
More explanation on the method used can be found in the following previous
article:

Willis, P; Ries, JC. 2005. Defining a DORIS core network for Jason-1
Precise Orbit Determination based on ITRF2000, Methods and realizations,
JOURNAL OF GEODESY 79 (6-7):370-378, DOI: 10.1007/s00190-005-0475-9

Best regards
