Subject: IDS CC - DPOD2020 version 5.0



Dear IDS users,

The 5.0 version of the DPOD2020 (DORIS extension of ITRF2020 for Precise Or=
bit Determination may be soon available for download from the CDDIS and fro=
m IGN.
That version is deduced on the position and velocity cumulative solution ba=
sed on the latest IDS weekly combined solutions from 1993.0 to 2025.5. Note=
 that the version 5.0 is aligned onto the ITRF2020-u2023 solution.

The new solution is available in both SINEX and text format from either the=
 main DPOD directory (dpod2020_current.snx.Z or dpod2020_current.txt.Z) or =
the DPOD2020 subdirectory (dpod2020_050.snx.Z or dpod2020_050.txt.Z).
I remind you that since version 2.0, the DPOD2020 solutions include both se=
asonal (annual and semi-annual) and post-seismic deformation corrections. T=
hus, for that 5.0 version, the seasonal and PSD corrections are given by, r=
espectively, dpod2020_050_freq_corr.txt.Z (dpod2020_current_freq_corr.txt.Z=
) and dpod2020_050_psd_corr.txt.Z (dpod2020_current_psd_corr.txt.Z) files.

As in version 4.0, to help the users to easily identify the DORIS stations =
which were operational at the date of the release of the DPOD2020 version 5=
.0, the end dates of these stations in the SOLUTION/EPOCHS of the SINEX fil=
e are set to 49:365:86399.

If you have any question and/or remark, please.

Best regards.
Guilhem
