That looks good, except no PPS.

Look at the gpsd debug output:

# gpsd -nND 6 /dev/ttyAMA0 |& fgrep PPS

Should get lines like this:

gpsd:PROG: KPPS:/dev/pps0 assert  1518138392.000000408, sequence: 6041142, 
clear   0.000000000, sequence: 0 - using: assert
gpsd:PROG: KPPS:/dev/pps0 Assert cycle: 1518138392000000, duration:       0 @  
1518138392.000000408
gpsd:PROG: PPS:/dev/pps0 Assert cycle: 1518138392000000, duration:       0 @  
1518138392.000000408

All should work fine.  Works for me.  Check your version:

# ntpshmmon -V
ntpshmmon: version 3.18~dev (revision release-3.17-36-g9f6d73c7)

Yes, ntpq -p
