I don't use RPis, so this is Debian experience. Use the latest version
of gpsd you can get. However, "apt update" won't do that for you. It
updates apt's information. Once you do that, then run "apt upgrade" to
bring your system up to date. You should do that daily, or see
unattended-upgrades. After that, "apt show gpsd" will give you a bunch
of information, including the version.

You can also build from source. https://gpsd.io/building.html

There is some information on using systemd with gpsd in the gpsd docs.

You do not want to disable systemd, despite Gary's disdain for it.
Doing so will leave you with a massive mess and may render your
system unbootable. What you want to do is either 1) remove gpsd from
systemd's control or 2) get the systemd configuration working to suit
your application.

To disable systemd's influence on gpsd, "systemctl stop gpsd; systemctl
disable gpsd; systemctl stop gpsd.socket; systemctl disable
gpsd.socket". This will leave systemd intact for other services. Now
configure as the non-systemd parts of the gpsd docs indicate.
