A Method for Assessing the Robustness of the Autonomous Navigation System of a Spacecraft Based on the Theory of Experiment Planning

A method for estimating the robustness of an autonomous spacecraft navigation system to the impact of perturbing factors of various physical nature is proposed. The methodology is based on the methodology of G. Taguti and the theory of experiment planning, in accordance with which the calculated ratios are obtained for estimating the robustness of the autonomous navigation system of a spacecraft to various perturbations of the orbital flight. The adequacy of the methodology is confirmed by the example of an autonomous spacecraft navigation system, including on-board optical-electronic, radio engineering and computing facilities. The proposed technique is universal and can be applied to navigation systems of other moving objects.
