面向应急观测的虚拟星座任务规划技术

Virtual constellation task planning technology for emergency observation

虚拟星座为充分利用卫星资源提供了一种高效的解决方案。首先研究设计了任务与资源管理、任务与资源匹配、协调与任务规划的三层协调运行机制,建立了基于多智能体的三层动态交互式体系结构模型;然后通过基于改进合同网协议算法模型,研究虚拟卫星协同任务的招标对象筛选策略、协商合同投标方法、协商合同评标方法;最后针对海上目标监视搜索场景构建仿真实验用例,仿真结果验证了虚拟星座的运行机制和体系结构的合理性、可行性与基于扩展合同网协议的虚拟星座任务规划算法的有效性和正确性。

Virtual constellations provide an efficient solution for making full use of satellite resources.Firstly,it studies and designs a three-tier coordinated operation mechanism of task and resource management,task and resource matching,task coordinating and planning.A three-layer dynamic interactive architecture model based on multi-agent is established.Then,this paper studies the screening target selection strategy of the virtual satellite cooperative task,the negotiated the contract bidding method and the negotiated the contract evaluation method based on the improved contract net protocol algorithm model.Finally,a simulation experiment case for the maritime target surveillance search scenario is established.The simulation results verify the rationality and feasibility of the operation mechanism and architecture of the virtual constellation.And the simulation results also verify the feasibility and validity of the virtual constellation mission planning algorithm based on the extended contract net protocol.
