[MIRROR] Add pAI internal GPS to possible software (#3184)

* Add pAI internal GPS to possible software (#56404)

pAIs are now a useful space travelling companion, they can help you
navigate if lost (although only the pAI has the GPS view, so they'll
need to communicate the information). If you're holding a GPS, then the
pAI can find you even if you get separated.
