Given the relative positions of the stars haven't moved visibly in thousands 
of years.  We can aim a fixed vector.  The only problem is earth orbit around 
the sun.  If beam array isn't a ring around the sun, I.E. if its around a 
point in orbit, the ship would have to follow the beam in a helical course 
around a direct vector from the sun, toward the target star.  

No serious math needed, or really possible.  We can't aim the beam because we 
can't know where the ship is to aim it at.
