systemd is NOT part of gpsd.  It is often the cause of pain for users.

So your GNSS is on /dev/ttyAMA0, the RasPi serial port?

What is your GNSS receiver model?

gpsd does not pass on SHM(1), the pps, unless SHM(0) is also reporting time.

That means your running gpsd is NOT running.

gpsmon is not well supported, always try cgps first.
