The closed-loop optimal guidance problem of the multi-objective and multi-constrained autonomous rendezvous with angles-only navigation is investigated in this paper. Firstly, considering the observability and robustness requirements, the performance indexes of the multi-objective optimization of the angles-only navigation and rendezvous guidance are established. On this basis, the objective function of the multi-objective and multi-constrained optimal rendezvous problem, and the solution method of the optimal guidance problem based on convex optimization are presented. Secondly, the framework and solution of the closed-loop angles-only navigation and guidance are proposed according to the “coupling” relationship between the navigation and guidance. Finally, the effect of the observability on the navigation and guidance performance is analyzed by simulation, and the effectiveness of the proposed method is verified.
