This goes into I Don't Know What I Don't Know Dept. (sorry Mad magazine)

A patron was telling me that the way the GPS is so accurate is because it uses the phones radio... Didnt know that either. (i mentioned to him that there is one spot in MA where our google directions are off by 1/2 mile.. Same place every trip.)

It's called Assisted GPS: https://en.wikipedia.org/wiki/Assisted_GPS

It speeds up getting an accurate location, doesn't provide a more accurate location than GPS.

GPS on is generally accurate to around 5 or 6 metres. That's the technology on it's own.
