分布式卫星在轨仿真系统研究

Study of Distributed Simulation System for Satellites on Orbit

为了给操作者提供全面且直观的卫星在轨信息,采用分布式体系结构构建基于虚拟实现的卫星在轨仿真系统。系统采用可扩展的接口,由功能相对独立的模块组成。讨论系统仿真状态的管理策略,分析系统的仿真推进方式与时空一致性问题,给出系统仿真流程。该系统结构简洁,网络数据吞吐量小。

To provide operators with complete and visual information of satellites on orbit, this paper builds a simulation system for satellites on orbit based on virtual reality technology by using distributing architecture. The system is composed of independent modules which adapt extensible interface. Management strategy for simulation states is discussed and the advance mode of simulation execution and coherence of time and space. It proposes the simulation flow. This architecture is simple and efficient and the data throughput is small.
