Development and Ground-to-Space Consistency Assessment of a Ground Simulation and Verification System for On-Orbit Servicing Spacecraft

In the field of on-orbit servicing simulation and validation, this paper proposes an uncertainty quantification-based framework for evaluating ground-to-space consistency in spacecraft simulations. The framework analyzes sources of uncertainty that cause discrepancies between simulated and actual on-orbit conditions. Through uncertainty propagation, it quantifies the impact of these uncertainties on the simulation's fidelity to the actual orbital environment. This offers quantitative justification and prioritization guidance for reducing key sources of uncertainty. Furthermore, this paper introduce a dual six-degree-of-freedom (6-DOF) ground-based physical simulation test system as an experimental validation platform. This work innovatively and systematically introduces uncertainty quantification into the consistency evaluation between ground and space, and establishes a comprehensive evaluation framework along with an experimental verification system.
