Automatic algorithm for accurate numerical gradient calculation in general and complex spacecraft trajectories

An automatic algorithm for accurate numerical gradient calculations has been developed. The algorithm is based on both finite differences and Chebyshev interpolation approximations. The novelty of the method is an automated tuning of the step size perturbation required for both methods. This automat...
