Abstract

Passive collision avoidance mechanism are effective for ensuring the safety of spacecraft formations during the reconfiguration process. This paper investigates the combined in-plane and out-of-plane formation reconfiguration, while incorporating passive collision avoidance constraints. We design a low-collision-risk impulsive maneuver sequence using the relative Eccentricity/Inclination (E/I) vectors theory and conduct a comprehensive passive safety analysis. Furthermore, we introduce an analytic, passively collision-free maneuver strategy by deriving constraint-satisfying solutions for the relative E/I vectors reconfiguration path. For the first time, our approach achieves theoretical completeness in passive collision avoidance, significantly enhancing the safety of transition configurations compared with existing analytic solutions. Finally, simulations results show that our approach offers substantial improvements in reconfiguration passive safety while incurring negligible additional fuel consumption in comparison to existing solution.
