Abstract:

In the face of the increasingly complex space security situation, this paper proposes an approach based on spacecraft reachable domain for spacecraft maneuvering approach threat calculation, assessment, and avoidance. Firstly, a general method to solve the reachable domain for spacecraft with single limited-magnitude impulse based on the reachable criterion is presented. Secondly, the region in the threat domain of on-orbit spacecraft is calculated by judging the position relationship between its orbit and the reachable domain of incoming maneuvering spacecraft which is the danger area. Thirdly, a threat evaluation index is defined by means of the time two spacecraft enter and exit the danger area. The threat of on-orbit spacecraft is measured from two aspects: position matching and time window matching. Based on minimizing the danger area, an active avoidance strategy of spacecraft with optimum multi-impulses maneuver is given to avoid the danger area. The simulations show that the on-orbit spacecraft can avoid the danger area while satisfying the given constraint conditions, and return to the proper orbit with minimum fuel consumption.
