A method to reconstruct the flight path of a symmetric flight, by representing this path by a set of splines, was applied to a three-dimensional flight over a rotating Earth. Results are comparable in accuracy and computing time to the Kalman (square root information) smoother, but reduction in computing time seems feasible.
