Sounds like what gpsmon is supposed to do.  I never tell anyone to use
gpsmon.  It is too GPS receiver dependent.  I tell them to use cgps.

Usually caused by a too short terminal window.  It needs at least 24
rows, and works better with many more.

"well-organized" is being generous.  Why try within our limits.

Cloning the NTPsec repo should be hard to mess up.  If it fails again
send us what your screen showed.

That would do it.  Common problem.
