DVD-COOP for Maneuver Path Optimization of Conjunctive Resident Space Objects for Space Traffic Management

摘要

Collision avoidance is one of the critical tasks to keep geospace safe and efficient. The detection and resolution of conjunction is a prerequisite for collision avoidance. In AMOS 2017, we reported a study of the DVD-COOP algorithm/program, based on the dynamic Voronoi diagram 3D spheres, which showed a proven mathematical capability together with implementation to detect all conjunctions without any missing case. In this paper, we report a new capability of the DVD-COOP algorithm which, given a detected conjunction, produces the optimal maneuver plan by quickly evaluating alternatives using the event history stored in the COOP-HSTRY file. The DVD-COOP algorithm, with a strong scalability, seems to play a key role for Space Situational Awareness and Space Traffic Management.
