I wish to solve the inverse geodesic problem numerically using http://geographiclib.sourceforge.net/html/classGeographicLib_1_1Geodesic.html#a455300c36e6caa70968115416e1573a4, and to finish off I need to specify the "equatorial radius". I am not too familiar with this, and do not see immediately what I would define as "North" or "South" in the orbital plane.
Does the "equatorial radius" here refer to the semi-major axis, or perhaps the apocenter or pericenter?
