This is the link to the previous thread on GPS accuracy etc I referred to in my post. FYI

How precise can phone GPS tech be right now?

Aren’t the first two kind of dependent on how many cell towers or wifi hotspots you’re within range of? I mean, they’re both basically identifying transmitters of known range, deriving a range based on signal strength, and overlapping those range circles and seeing where they all overlap. Seems to me that to a certain extent, more is better.
