****************************************************************************** dorismail 21-Mar-2017 16:32:18 Message No 1069 ****************************************************************************** Author: Moreaux Guilhem Subject: IDS CC - DPOD2014 Dear IDS users, The first version of the DORIS extension of ITRF2014 for Precise Orbit Dete= rmination (DPOD2014) is available at the CDDIS (ftp://doris.ign.fr/pub/dori= s/products/dpod/) and IGN (ftp://cddis.gsfc.nasa.gov/doris/products/dpod/) = data centers. Few things to know about DPOD2014: 1. The DPOD activities are now performed by the IDS Combination Center. 2. The DPOD2014 solution is mostly based on the latest DORIS position = and velocity cumulative solution (aligned to the ITRF2014 - see subdirector= y doris/products/sinex_global/ids/) from the latest IDS combined series. So= far, the mean positions and velocities of the very old stations (with obse= rvations before 1993.0 - not included in the IDS combined series) are extra= cted from DPOD2008 v1.14 (after alignment to ITRF2014). Positions and veloc= ities of the newest stations not included in the IDS combined series are de= duced from either the DORIS local ties (if an older DORIS station is part o= f the IDS cumulative solution) or the DORIS mails from IGN. Note that such = information is given in the header of the DPOD2014 solution files. 3. After some preliminary validation tests by the IDS Combination Cent= er, the DPOD2014 solution is validated by the POD validation group (P. Will= is, F. Lemoine, A. Couhert, N. Zelensky and Ait Lakbir Hanane). 4. The DPOD2014 solution will be updated two times a year. 5. The DPOD2014 solution is available in both SINEX and text formats. 6. The updated version of the DPOD2014 will be always denoted by, resp= ectively, dpod2014_current.snx.Z and dpod2014_current.txt.Z. That version w= ill always correspond to the latest DPOD2014 solution (available in the sub= directory doris/products/dpod/dpod2014/). 7. The previous DPOD2008 (resp. 2000, 2005) solutions will remain avai= lable at doris/products/dpod/dpod2008 (resp. 2000, 2005). 8. More information on the IDS combination center products is availabl= e at http://ids-doris.org/analysis-coordination/combination/activity-produc= ts.html 9. All your questions and comments on the DPOD2014 are welcome at ids.= combination@ids-doris.org Best regards. G.
