Does anyone know if PRSolve applies the Klobuchar coefficients using either sp3 or broadcast orbits? I know Klobuchar coefficients are in the navigation file header but I have no idea if they are used. The reason I ask is I'm applying more accurate TEC corrections to a RINEX file and I want to make sure PRSolve doesn't re-correct it. Thanks for your help in advance!

I did a brief inspection of PRSolve's code and I saw no reference to the Klobuchar coefficients. However you never know what could be buried in the library code. I really doubt they are hard-coded; they have to come from data. If you really want to make sure the correction is not applied, I recommend you remove them from the RINEX data. If you are using SP3 files, then naturally the Klobuchar model will be absent. Also -- it looks like PRSolve by default performs the dual frequency correction. I would remove all obs from your file except for C1. EditRinex can do that for you.

No, PRSolve does not use the Klobuchar coefficients. You may choose the frequency to process (L1, L2 or L3: the iono-free combination - 3 is the default) using --Freq

Great thanks!

Oh and I just found out you can use --forceCA instead of removing the other data
