A Heuristic Approach to Dynamic Rescheduling of AEOS System

摘要

Agile Earth Observation Satellites (AEOS) system will be an important direction,for the AEOS's agility and bign return.Currently,most of the Earth Observing Satellites are totally controlled from the ground:operation schedules are regularly made on the ground,uploaded to the satellite and then,executed on-board step by step.Facing the new AEOS development and new on-board decision-making requirements,this paper proposes a Dynamic Rescheduling System of AEOS within a Monitoring,Reactive and Repairing Architecture (MIRRA) for protecting satellite's onboard resources and a Dynamic Heuristic Algorithm for Rescheduling,as the core part of the systems.Finally,An experimental evaluation performed on some benchmark sets confirms the validity and effectiveness of this Dynamic Rescheduling System.
