It is not possible with any GPS system because a raw GPS position at any instant can be off by less than 1 meter to over 100km due to dignal noise, reflections interferance etc.
My GPS test app is getting GPS position updates approximatly every second. What you need to do with these updates is some form of windowed averaging (average of last n-fixes throwing away any fix which is too far away) to give you a more accurate position. How many fixes and how big your window should be is up to your application. -- RichardC On Oct 19, 10:08 am, "[email protected]" <[email protected]> wrote: > Hello together, > > I want to develop a cellphone app, which heavily relies on the GPS > function. > I tried it with the iPhone first, but it wasnt precise enough.
