I know that the absolute precision of position detection for gps hardware isn’t that accurate.
But assume that I have two androids and they are syncing each other at one place. In which precision (horizontal area) can I predict the other android position if the devices don’t walk away too much (e.g. 1km) ?
Would this as bad as several meters? Or could I increase the precision in a different way when I have two or more androids in an area of 1km^2? A precision of ~10cm would be nice.
I think I found a way to improve precision of Android’s GPS: take a look here on how to obtain the user location via GPS, Cell-ID or WI-FI
