I use this hiking sometimes. Not as good as GPS obviously, but better than AllTrails.
It is GPS.
Also, "GPS" in the United States colloquially refers what people in the UK would call "sat-nav" not to the satellites + protocol (what it actually means on paper).
Maybe? When hiking it makes some sense to forego GPS to save battery power. I didn't consider that possibility when I commented earlier, but in my defense the context of the comment is using maps without an internet connection.

Sure, but sat-nav doesn't require internet service...
