DPOD2008

Terrestrial reference frame for precise orbit determination

derived from ITRF2008

 

 

Description of earlier work (DPOD2005) can be found in Willis, P., Ries, J.C., Zelensky, N.P., Soudarin,, L., Fagard, H., Pavlis, E.C., Lemoine, F.G. (2009) DPOD2005, an extension of ITRF2005 for precise orbit determination, Advances in Space Research, 44(5), 535-544, DOI: 10.1016/j.asr.2009.04.018

This work is being conducted by the following indiviuals (by alphabetical order): Donald F. Argus (Jet Propulsion Laboratory, USA), Luca Cerri (CNES, France), Mike B. Heflin (Jet Propulsion Laboratory, USA), Frank G. Lemoine (NASA/GSFC, USA), Guilhem Moreaux (CLS, France), Michiel Otten (ESOC, Germany) John C. Ries (UT/CSR, USA), Laurent Soudarin (CLS, France), Pascal Willis (chair, IGN, IPGP, France), Nikita Zelensky (SGT, USA).

 

Access to DPOD2008 (latest version = 1.14): text format or SINEX format

 

Differences with earlier versions

 

In the following Table, we use the following conventions:

- more details can be obtained for any specific station in blue in the left column

- this Table only displays the number of discontinuities (in position and/or in velocities) as well as the number of periods for which data should not be used for precise orbit determination. More details can be obtained in the DPOD2008 file (see above)

- as integrity is an important factor for DPOD2008, coordinates/velocities are first proposed by a member of the group (status is then TBC = To be confirmed). When this information is confirmed by at least another member of the group, is possible using an independent approach, coordinates and velocities are then considered as final (X). Otherwise, when DORIS coordinates and velocities are not yet available, the following convention is used: TBD (To be done).
