[Proj] System 42/83 (S42/83)

[ErichS]

Hello all,

I'm trying to use coordinates in S42/83, a system often used in eastern Europe
(e.g. Russia) and partially in East-Germany ("Deutsches Heeresgitter").

It's similar to Gauss-Kruger (Gauß-Krüger) (i.e a transverse mercator
projection) but it uses 6 degrees wide stripes instead of 3 degrees.

And its first meridian is at 3E.

Is there a possibility to define these parameters in cs2cs/proj4?

As ellipsoid "Krassovski" is used (+ellps=krass).

Many greetings
Erich
