Hi there! The code smoothing in DiscFix is done using the phase measurements? Thanks.

Yes, but its not really "smoothing" in the sense of a filter. The raw dual frequency pseudorange and phase for an entire satellite pass are used to solve for the phase biases, which are then used to debias the phase and replace the pseudorange with an equivalent built from the phases.


OK, thanks for your reply. If I have a RINEX file with only C1 and L1, is there any tool in gpstk I can use to smooth C1 pseudoranges using L1 phase, with a Hatch filter for example? Thanks again!

Yes, you can do this with the class 'CodeSmoother', and you should mark the cycle slip with 'OneFreqCSDetector'. Please take a look at example7 for detail.
