Yes, I am using rtkget to download the relevant SP3 (IGS_EPH) and CLK
(IGS_CLK) files also. I am not using any IONEX file since I don't know
where to get that.

I also tried submitting the same RINEX file to the online tool CSRS-PPP
over here:
This online tool works with the automatically generated RINEX 2.11
Observation data file from my Dicom GTR51. I did not submit a separate
navigation data file to the site.

However with RTKLib I cannot get PPP calculations to work with just the
Observation+SP3+CLK data.
As described before RTKPOST works when I manually generate both Observation
and Navigation rinex files from the Dicom - but this option is not
automated in the Dicom user interface - so it's not really an option for
continuous use.
