    My software says 54.46 degrees for the initial great circle heading.
    
    Such differences are usually because of the underlying math routines
    used and often the display routines for showing things to a given
    precision.
    
    Without seeing your code it would be hard to say exactly what the
    problems are.
    
    If you wish to privately send me the code to glance at, I would be
    happy to see if something jumps out at me.
