Abstract
Aimed at the problem of space rendezvous using angles-only measurements, relative navigation integrated with closed-loop guidance is developed based on observability analysis. Firstly, the systemic filtering model is established, based on which the observability is investigated from a novel prospect and the observable condition is obtained. Then, integrated with multi-pulse sliding safe guidance strategy, the coupling relationship between angles-only relative navigation and guidance is analyzed and the mathematical expressions are obtained. After that, the integrated scheme of relative navigation and closed-loop guidance is designed by using the coupling expresses. Finally, Monte Carlo simulations are conducted to validate the approach and the performance of navigation and guidance with different accuracies of sensor and initial relative states is analyzed.
