摘要
全球或区域导航精度因子(DOP,Dilution of Precision)仿真分析是全球导航系统性能指标仿真分析与评估的重要组成部分。研究了DOP的相关概念和算法,分析了DOP的可用性算法,采用基于仿真模型可移植性标准(SMP2.0)的模型开发与集成方法,设计、开发、集成和运行了面向DOP的导航系统仿真模型,并实现了支持DOP仿真分析的软件工具,最后针对GALILEO系统在中国区域的导航精度因子进行了仿真分析,验证了导航仿真系统中基于SMP2.0方法集成具有良好合理性和移植性的优点。
The global or regional DOP （Dilution of Precision） analysis is a part of the simulation analysis and evaluation of performance for the navigation system. The concept and algorithms of DOP were introduced firstly, and then algorithms of the availability of DOP were researched. The SMP2-based models development and integration method was applied to design and develop simulation models of Navigation System for DOP, and analyze the regional DOP of Galileo Satellite Navigation System in China. Lastly, the development and integration method of simulation models based on SMP2 for the navigation system has the following advantages： fine logical and nice portability.
