Generally, they are based on the fact that this chamber possesses a similar geometry to the ellipsoid of revolution, or, still, to a truncated prolate spheroid (TPS), implying that two of its axle shafts must have equal measures [4-9].
The principal difficulty is that the general geodesic on the ellipsoid of revolution is a space curve, and hence the distance and azimuths cannot be expressed directly in terms of the geographical coordinates of the endpoints.
