I want to post-process GPS files via Differential processing (DGPS/DGNSS mode)
using rtklib (http://www.rtklib.com/).
I have rover and base observations in .rinex format.
I took FINAL satellite orbit solutions from NOAA-CDDIS archive (https://cddis.nasa.gov/Data_and_Derived_Products/GNSS/orbit_products.html) in the following format:
Using the utility rtkpost from rtklib I get the error "no nav data".
Is that a problem of the sp3 format? (sp3 is listed within the acceptable formats)
Did I download completely wrong files for the satellite orbit solutions?
