You will get better luck with ubxtool.

There are already active open threads on this. Check the archives.
TL:DR: Something weird with the 9-series. Possibly due to raw
meassurements not taken on the top of the second.

Someone still uses the long abandoned Ashtech? Kill it.

There are many good RINEX 3 programs. No point to RINEX 2 as it does
not support newer constellations.

Same problem as other have, the 9-series is using a weird epoch:
> 2020 04 28 01 40 30.0089999 0 11
Note the 30.0089999? It should be 30.0000. That is direct from the
u-blox. No way to fix it.
