Hi Juan,
The way our devices record the raw data is within the industrial standards. You can enable the log at any time period so we can’t ensure it is started in an even second. That’s why our logs are not even on them as well. There are no issues behind it.
What you get is a precise log without an additional interpolation of the data. Still, it’s possible to do it if you have a need for it. This option is available in post-processing with RTKLib as well. We’ve described it in one of the posts, I’ll leave a link to it for a brief consultation.
