Hi,

is there a possibility to use the "differential GPS" (dgps) in
android?? The accuracy of dgps is (how i read it) 2m, while the
accuracy of "normal" gps is ~15 to 25m. Or can i manually calculate
the dgps. i doesnt find a equation or something like that.
Why i ask that: i track some gps points and save them into a gpx file.
i let the gpx file draw on http://www.gpsvisualizer.com and i saw,
that the accuracy is really only 15-25m.
Btw, how can i interpolate the gps points in a map view. The track
looks wavy, but i want a nearly straight line.

Thanks,
Stefan
