Your cause and effect chain is off.  If ntpshmmon shows a timeout, then
your gpsd is not working yet.  And ntpshmmon shows the input to ntpd.  So
no need to look at ntd until ntpshmmon is working.

The flow is:  GPS output to serial port and PPS.  gpsd read the serial port
and PPS.  gpsd outputs to SHM, which ntpshmmon shows.  ntpd reads from
SHM.

Yes, if ntpshmmon not wotking, then ntpd will not work.  The only way
ntpshmmon is not working is if gpsd is not working properly.

gpsmon is part of gpsd.  I prefer cgps, but either can work.
