What does each column on a rinex GNSS observable file mean?

Question

I am trying to understand the data from a GNSS observation rinex file but cannot figure out what each column represents as the PDF (for rinex 3.02) is not very clear.

I would like to know what each column in the epoch corresponds to. Does anyone know?

Thanks

Answer 1

The columns are the observations (pseudo ranges/code, carrier phase, dopper, snr/cn0). The problem/issue with RINEX that you have is the order of columns is arbitrary. The columns are specified in the RINEX header.

If you post an example I will expand on my answer. Post the header, and an example line/row.
