The GPS in tractors (with the help of RTK) has repeatable sub-inch accuracy.

If thats the case is it a consistent offset so if two receivers are 24 inches apart it can calculate an accurate azimuth?

GPS can not give you a magnetic direction unless it is moving. It knows where you are, but not which direction something else is unless it has a vector to work with (i.e. you're moving).
