The url given seems to be incorrect or out of date - has anyone got the
correct link?

The UTM grid is a one kilometer grid with an orientation to true
north called "Grid North" and has easting and northing values
marked on the edges of printed maps.
The gauss-krueger coordinate system also has a one kilometer grid
with an orientation to true north called "Grid North" and has easting
and northing values marked on the edges of printed maps. A transformation
of the two grids should consist of translation and rotation matrices, with
constants being a function of location.
I have two sets of Berlin topographic maps. 1:25,000 and 1:10,000 dated
1986. The one-kilometer grid is not UTM. I found the angular orientation
of the grid with respect to true north to be almost identical to that of t
he UTM one-kilometer grid for this region.
Applying a linear transform of 47 meters easting and -2430 meters northing
I can convert back and forth between UTM and the grid used on these
Berlin maps. The transform values vary about 5 meters from opposite sides
of area covered in the Berlin map sets.
Using an HP-48SX and placing the easting and northing values on the stack:
UTM->GK
<< ->V2 [47 -2430] - V-> >>
GK->UTM
<< ->V2 [47 -2430] + V-> >>
However, all this is all unsatisfying.... I'm still seeking a definition
of the GAUSS-KRUEGER system that will allow the relationship between it
and UTM or LatLon or ECEF X, Y, Z.

Attempted to send you a message re UTM to Gauss-Krueger system conversion
-- don't know if it made it...
I suggested that you may want to look into TNTproducts by MicroImages,
Inc. as I believed they support that.
Checked today and they do. Online documentation provides info on system
conversion... The Map Calculator and other georeferencing processes do it.
TNTlite is downloadable via web-page or they provide it on CD-ROM for
($25) cost / handling... http:// www.microimages.com. Professional
products are available for larger scale products.
Also since I had the reference on my desk @ work, you should also refer to
"Map Projections -- a Working Manual by the USGS, Professional Paper 1395"
(GA110.S577, 1987, 526.8, 87-600250 -- first printing 1987, second 1989).
Good luck.
