May be you can add in your synoptic diagram:
- Georges Boissaye du Bocage method (Universal circle, 1682), which is tied to stereographic projection (but did not use complex algebra !)
- Pierre Semirot method (1961), which is a mechanical one
"Navigation aérienne et nautique : nouvelle méthode de calcul", Journal des Observateurs, Vol 44 1961
- and what about the "astrograph" ?
I can't do more now, because Paris attack consequences are catching my attention.
