If str2str_tcp is restarted, gpsd is stopped and doesn't restart

Creating a .conf file in /etc/systemd/system/gpsd/ seems a good solution:
https://serverfault.com/questions/840996/modify-systemd-unit-file-without-altering-upstream-unit-file

example: a restart.conf file with this in it:

[Service]
Restart=always

It was easier to add the command directly inside the service file, as I already do some modifications in it during the installation.

This seems to work, but need more tests:

[Unit]
Description=GPS (Global Positioning System) Daemon
Requires=gpsd.socket
After=str2str_tcp.service

[Service]
Type=forking
EnvironmentFile=-/etc/default/gpsd
ExecStartPre=/usr/bin/systemctl is-active str2str_tcp.service
ExecStart=/usr/sbin/gpsd $GPSD_OPTIONS $OPTIONS $DEVICES
Restart=always
RestartSec=30

[Install]
WantedBy=multi-user.target
Also=gpsd.socket

⚠️ Check the path to systemctl with which systemctl and edit it inside the gpsd unit if needed.

EDIT : It looks like the absolute path to systemctl is not needed anymore as systemd search for the executable in various path. We can check this with sudo systemd-path search-binaries-default
