摘要
针对当前卫星仿真中仿真工具可扩展性差和空间环境模型复杂的问题,设计并实现了一种基于HLA的分布式卫星仿真系统。在架构设计层面,遵循分布式系统设计思想,把系统自底向上划分为数据支撑层、仿真支撑层和仿真应用层,并基于负载均衡的考虑,设计了四个功能集中的仿真应用子系统。在系统实现层面,结合虚拟现实技术,实现了想定方案的灵活配置以及星空环境和在轨卫星的实时渲染,搭建了支持多种卫星仿真应用的通用仿真运行平台。在仿真应用层面,实现了在此平台上对卫星编队变轨过程的仿真,并实时采集仿真数据对仿真结果进行分析和评估。
To deal with the problem of poor extensibility of current satellite spaceflight simulation tools and high complexity of space environment model in satellite simulation, an HLA-based distributed satellite simulation system was designed and implemented. In infrastructure design level, according to the idea for distributed system, this system was divided into data support layer, simulation support layer and simulation application layer. In consideration of load balance, four simulation application subsystems were designed for special use. In system implementation level, flexible scenario configuration was realized. Star field environment and on-orbit satellites were rendered in real time by introducing virtual reality technology. This system provided an all-purpose simulation platform for various space system applications. In simulation application level, orbit changing process for satellite formation was simulated on this platform. Real-time experiment data were collected for evaluation and analysis.
