The traditional processing tools (GNSS Solutions) for observation files from PM500, PM800, PFx00, ProMark 2, ProMark 3 and ProMark 120 receivers no longer work after the WNRO (Week Number Roll Over) event of 6 April 2019.

This video shows how to convert observation files to RINEX using the latest Spectra RINEX converter, then process the resulting files against CORS using CHCNav's CGO2.
