FWIW I'm using the -G option via systemd reliably on Arch (Arm) so long
as I do NOT enable the systemd socket.
address@hidden cat /etc/gpsd
# Default settings for gpsd.
START_DAEMON="true"
USBAUTO="true"
OPTIONS="-G -n"
PORT="2947"
SOCKET="/var/run/gpsd.sock"
DEVICES="/dev/ttyAMA0"
$ cat /etc/systemd/system/multi-user.target.wants/gpsd.service
[Unit]
Description=GPS (Global Positioning System) Daemon
#Requires=gpsd.socket
After=chronyd.service
[Service]
EnvironmentFile=-/etc/gpsd
ExecStart=/usr/sbin/gpsd -N $OPTIONS -P $PORT -F $SOCKET $DEVICES
[Install]
WantedBy=multi-user.target
#Also=gpsd.socket
However I have to do things different on the client machines.
Evidently a local gpsd instance won't listen to remote gpsd instances
directly. Instead, I have to use socat and gpspipe to create a virtual
serial GPS, then point the local gpsd instance to that port. I'm doing
this through a NetworkManager dispatcher script on the client machines.
$ cat /etc/NetworkManager/dispatcher.d/20-RemoteGPS
#!/bin/sh
ESSID="MyWiFiNetwork"
interface=$1 status=$2
case $status in
up)
if iwgetid | grep -qs ":\"$ESSID\""; then
sudo socat exec:"'gpspipe -w rpi3-1:2947'"
PTY,link=/dev/gpsRMT0,raw &
sleep 5
sudo chown root:uucp /dev/gpsRMT0
sudo chmod 0777 /dev/gpsRMT0
sudo systemctl restart gpsd.service
fi
;;
down)
sudo killall gpspipe
;;
esac
It's cludgy but it works reliably.

Systemd has worked really well so far. This issue crops up also
when
running gpsfake (unrelated to systemd) and this is the use case I'm
targeting currently. Seems that since two different methods of
starting gpsd are having the same outcome that there may be a bug
on
the gpsd side?
Can you put together a simple test for what you see, that does not
use
systemd?
