[Proj] Accuracy of projections

[maurer at shhinfo.de]

Hello,

I'd like to transform GPS (DGPS) generated coordinates from WGS84
(lat/lon) to Gauss-Krueger coordinates on Bessel ellipsoid(epsg 31463). Is
it possible to receive an accuracy <1 meter using proj.4 standard epsg
file? (I don't really want to generate my own helmerttransformation and
transformationparameters...).

Kind regards
Tobias
