3.17 is 5 years old. 3.22 is 18 months old. Best to avoid those.

How did you set u-blox binary mode? How did you look at the JSON?

Use cgps or xgps instead.

Then you are doing some weird configuration of the device.

We can't debug what we can't see. Send here the FULL build log. Did
you follow the build instructions in build.adoc?

gpsmon has its own, broken, decoder for u-blox raw.
If you send us the raw data you see then someone can look at it:
gpspipe -R -x 20 > log.raw
Then send here log.raw. As well as how you configured the device.
