enough away. As I said it is pretty much Newton's method on a sphere,
and there are plenty of general results about convergence of that.”
The following outline comes to my mind:
1) Quantify how much the adopted procedure starting from some AP brings you closer to the correct position after one pass.
2) Apply the Banach fixed-point theorem.
