    No problem, usually a GC route is divided in a number of rhumb line tracks, and used to steer.

    The deviation between a true, constantly curved great circle course and a straight line approximation will be far less than your measurement uncertainty, especially for a running fix whose total duration is less than one hour.

    In other words, I would not worry about it and just assume a straight line course, instead of a curved course.
