服务段仿真(Service Volume Simulation,SVS)主要用于导航系统服务性能的分析与评估,是导航仿真系统的重要组成部分。在分析了导航系统SVS的特点后,建立了导航系统服务性能分析模型之间的数据流关系,采用SMP2.0(Simulation Model Portability)的基于组件的模型设计方法,提出了面向SVS的仿真模型框架,并基于此框架和SMP2.0的集成方法进行了导航系统SVS的模型设计、开发和集成。该框架包含空间段、环境段、用户段以及分析记录等模型、接口和组件,并通过面向导航系统的SVS仿真应用环境检验了该框架的合理性和可移植性。
Service Volume Simulation(SVS) is used for evaluating and analysis service performance of navigation system,and is an important part of the navigation simulation system.The features of SVS of navigation system were analyzed,and the data flow between models for analysis service performance of navigation system was established.The simulation model architecture for SVS was proposed,which was designed by component-based of Simulation Model Portability 2.0(SMP2.0),and the models of SVS of navigation system were designed,developed and integrated based on the architecture and integration method of SMP2.0.The architecture consists of the models,interfaces and components for space segment,environment,user segment and recording.Last the architecture is fine logical and nice portability in SVS simulation application development for navigation system.
