Thanks to all for your answers. I am designing a low cost automagic 
satellite dish pointer.

I was thinking that adding the magnetic compensation to the magnetic 
compass would be neat, but obviously I can't get it from the internet, 
still wondering how the GPS could provide a useful value if the modeling 
is difficult, varying widely in time and space.
