Research on cooperative interception method of non-cooperative targets in close approach to space station
Abstract
<p indent="0mm">With the increasing number of space debris, faulty satellites and other non-cooperative space targets, there are serious security risks to the on-orbit operation of the space station. Aiming at the problem of dynamic non-cooperative target interception in a fixed time, this paper proposes a cooperative interception method for space station close approach non-cooperative targets based on clustered micro/nano satellites. The method realizes the optimal path planning of dynamic targets on the basis of realizing the evaluation of interception time requirements. Firstly, the close-in non-cooperative target interception mission is analyzed, and the autonomous allocation of interception points, interception time constraints, fuel consumption constraints, formation configuration constraints and maneuvering capability of micro-nano satellites are considered comprehensively. On this basis, a fitness function considering multiple constraints is constructed, and a mathematical model of non-cooperative target interception path planning based on cluster micro-nano satellites is established. Finally, according to the given time constraints of the interception mission, an interception path planning algorithm based on internal and external nested optimization for multi-micro-nano satellite collaborative networking is proposed. Simulation results show that the proposed algorithm can successfully intercept non-cooperative targets in a fixed time.</p>
