A different method for the reduction of the 2-body fix, as well as other classic problems in celestial navigation, appears in the attached paper that is due to be published in Navigation (Journal of the Institute of Navigation). By mapping points on the sphere to complex numbers by stereographic projection, spherical trigonometry is reduced to plane trigonometry and simple arithmetic operations on complex numbers,
