Study On Multi-Satellite Simulation System Based On Multi-Agent Methods

In recent years,with the increasing number of satellites in orbit and the gradual improvement of satellite intelligence,multi satellite cooperative mission planning has become the research focus in the field of satellite applications.Multi satellite collaboration is often used to solve the observation task scheduling problem of multi imaging satellites,but the application research in space interception is less.Aiming at the problem of space attack,defense and confrontation in complex environment,adopting the way of multi satellite cooperative attack,through mutual cooperation and resource sharing among members,the system can realize dynamic allocation,which can improve the quality of task completion,increase the success rate of task,improve the overall operational efficiency,and reduce the task load of single interceptor.In the multi satellite attack task,not only the attitude and orbit of each satellite should be controlled,but also the relative position relationship between the satellites should be controlled to ensure the stability and reliability of the satellite formation.It is difficult to meet the real-time requirements of satellite attitude and position adjustment in constellation to avoid collision if all the ground measurement and control resources are relied on.Therefore,we need to introduce new technologies to reduce the dependence on ground TT &C resources through autonomous and distributed onboard management of satellites and their payloads.As a new generation of agent,agent has better flexibility and is more suitable for solving problems such as coordination and Optimization in complex systems.In this paper,the multi-satellite simulation system based on multi-agent system is designed and studied,and the related application and analysis test are carried out.In the process of design and implementation,firstly,the definition of agent and related technologies of multi-agent system are studied comprehensively,and four common structures of multi-agent system are summarized.On this basis,according to the specific functional requirements of the multi satellite attack and defense simulation system,the organizational structure and functional modules of the system are designed and programmed.Finally,the function and performance of the system are tested and verified by specific simulation tasks.
