卫星编队飞行仿真中STK-RTI中间件的研究

卫星在编队飞行任务分析与可视化动态场景仿真,能使多颗卫星保持相对协同工作,但与外界交互集成能力较差。为了能够成为HLA(高层体系结构)的联邦成员,设计并实现了连接STK与RTI的中间件。通过相关分析设计了STK-RTI中间件的功能结构,采用服务转换机制建立了STK/Connect模块功能函数和RTI标准服务之间的映射关系,实现了STK和其它联邦成员之间的交互,并在编队飞行仿真中对中间件的可行性进行了验证,拓展了STK的使用范围。

Research on STK- RTI Middleware in Simulation of Satellite Formation Flying

In the simulation of satellite formation flying,Satellite Tool Kit(STK) is powerful in space-analysis and visualization of dynamic scene simulation.There is weakness in the interaction with others.Aiming at the realization of joining STK into the federate,the middleware linking STK and RTI has been designed and implemented.A design involving the construction of the middleware and relationship between the parts was expounded.Emphasis was placed on the implementation of the mapping relationship between the API function of STK/Connect and the standard service.The middleware has been validated by the simulation of satellite formation flying.The scope of using the STK has been expanded.
