Resilience Analysis for Tightly Coupled Constellations of Teams

Due to the unrealistic of on-orbit maintenance in space, it is essential to enhance the constellation system's resilience, i.e., the ability of the system to withstand disruptions and return to a normal state quickly. In this paper, we propose a resilience analysis framework for tightly coupled constellations of teams. The maximum revisit interval is used as the key performance parameter of the system in the resilience measure. We first analyze the probability and the effects of the system's operation mode change, and then provide a Monte Carlo method for the system resilience quantification. Finally, a tri-satellite constellation of four teams is used as a case to verify the effectiveness of this method.
