中文摘要： 全球导航卫星系统（Global Navigation Satellite Systems, GNSS）是一个复杂的系统工程，计算机仿真是其实施必需的验证手段。为了克服传统封闭GNSS仿真环境中仿真模型资源数量有限、重用复杂、共享度低等缺陷，本项目提出构造一个开放可扩展的GNSS仿真环境，通过将来自不同机构的仿真模型在此环境中进行大范围的跨网络共享来提升GNSS仿真的能力。本项目拟对其中的两个关键问题进行研究，通过研究仿真模型全解耦服务化方法来实现GNSS仿真模型的快速接入、高度自治、良好的可配置性和交互性，为仿真模型在GNSS仿真环境中的大范围跨网络共享提供实现手段；通过研究仿真模型之间的关联关系和不同机制的关联关系表达框架来为仿真模型的快速筛选和快速匹配提供支撑，为仿真模型在GNSS仿真环境中构造仿真流程提供辅助手段。通过该项目的开展，将为GNSS仿真提供新的技术途径和手段。

英文摘要： The GNSS (Global Navigation Satellite System) is a typical case of complex engineering, and the GNSS Simulation provides necessary validation tool for its implement. To overcome the shortages of the traditional closed GNSS simulation environment include the limited number, the low sharing degree and the complicated reusing methods of simulation models, this project proposes an open GNSS simulation environment in which variety simulation models from different organizations of individuals can be shared across a wide range of network to promote the simulation capacity. Two key problems are planned to be studies in this project. A full-decoupled service method of simulation models is to be studied to fulfill the fast accession, the high degree of autonomy, the configurability and the interactivity of simulation models, thus provides an efficient way to share the simulation models across a wide range of network. The relationships among simulation models and the relationships expression framework base on different mechanism are to be studied to provide support for the fast selection and fast matching of simulation models, thus provides an efficient way for the construction of simulation processes. This project will provides a solid theoretical and technical foundation for the improvement of GNSS general design and system analysis ability.
