Abstract:

The development of mega-constellation brings hidden danger to the space security, so it is particularly important to conduct situational awareness of the status of mega-constellation satellites. A hierarchical dynamic mission planning method based on rolling planning framework is proposed by using a small-scale Walker-δ sensing constellation to achieve effective reconnaissance through a close flyby with mega-constellation satellites, considering the constraints of attitude maneuver time and load charge and discharge. The initial planning layer is based on the parallel planning principle and binary whale optimization algorithm (BWOA) to plan the multi-satellite sensing multi-objective problem. The replanning layer adopts the greedy dynamic adjustment strategy to assign the tasks that cannot be assigned in the initial planning results. At the same time, the optimization quality of the algorithm is improved by multi-rolling cycle planning. Simulation results show that the sensing constellation can complete the comprehensive and reconnaissance of mega-constellation satellites studied within 12 h after planning, which verifies the effectiveness of the proposed method.

Key words: mega-constellation, situational awareness, hierarchical task planning, binary whale optimization algorithm (BWOA)
