The spheroid is
Krassovsky (1946):

Semi-major axis:
a=6378245.000m

Semi-minor axis:
b=6356863m

(a-b)/a = 1/298.3

Map projection is
Gauss-Krueger(sp?)

This is very
similar to UTM but has unit (1.000) scale along
main

meridian of a
6-degree zone, whereas UTM has 0.9996 scale.

Northing ( x ) is
measured from equator,

Easting ( y ) is
represented as

n mmm
mmm

where n is zone
number (first zone is 0-6 degrees east of
Greenwich)

mmm mmm is meters
measured so that main meridian of the zone has

y=500
000m
