In the last case that can create a better locate than a phone could do by itself I believe, but our GPS guy has gone for the day (I'm still at work  ) so I'm not 100% sure. |
Probably more that it gets an estimate of the first unknown.. time.
But 10-25m accuracy all the way to 1-2.5km? That's like you have no GPS at all. That's basically cell tower triangulation. Total garbage. If I was a Bell subscriber I'd be screaming my head off right now.
