摘　　要：针对SiROS软件只支持C/S架构仿真的问题,设计了三类应用服务镜像将SiROS仿真软件部署在云平台上.基于Docker虚拟化、容器化技术将仿真需要用到的云端资源封装至Docker容器中,用户采用B/S架构连接云提供端Docker容器,在本地浏览器直接使用容器中分配的各类资源完成建模仿真任务.基于云平台的SiROS仿真软件是模块化架构,将仿真模块封装在功能包中,仿真时根据任务需求,利用分级启动方案加载特定功能包.建立了Secular_J2轨道外推仿真模型并进行了仿真实验,通过与卫星工具包分析软件仿真结果对比验证了B/S架构下SiROS软件仿真结果的准确可靠性.As the SiROS software only supported C/S architecture simulation,three types of application service images were designed to deploy the SiROS simulation software on the cloud platform.Based on Docker virtualization and containerization technology,the cloud resources needed for simulation were encapsulated into a Docker container.The user used the B/S architecture to connect to the cloud provider Docker container,and directly used the various resources allocated in the container to complete the modeling and simulation task in the local browser.The SiROS simulation software based on the cloud platform had a modular architecture,which encapsulated the simulation module in a functional package.During simulation,a hierarchical startup scheme was used to load specific functional packages according to task requirements.The Secular_J2 orbital extrapolation simulation model was built and simulated.Compared with the simulation results in software of satellite tool kit,the accuracy and reliability of the simulation results of the SiROS software under the B/S architecture is verified.
