摘　　要：导航系统精度(NSP,Navigation System Precision)分析是卫星导航系统定位、测速和授时性能仿真分析与评估的重要组成部分,NSP的可用性和连续性是导航系统服务能力的重要标志之一。研究了NSP的相关概念,分析了NSP的可用性和连续性算法,在此基础上提出了面向卫星导航系统的NSP仿真模型框架,并基于此框架设计和实现了支持NSP分析的插件工具,最后针对格网分辨率为5°×5°的区域格网进行了NSP的仿真试验分析,验证了提出的仿真模型框架和设计的插件工具的正确性。Navigation System Precision Analysis is a part of the simulation analysis and evaluation of the Navigation System＇s performance on positioning,velocity-measuring and time-telling,and the availability and continuity of NSP is an important symbol of service capability of the navigation system. The NSP concept was introduced firstly,and then algorithms of the availability and continuity of NSP were researched,based on these,model architecture of the NSP was proposed and the NSP simulation analysis system was designed and implemented,finally,the simulated experiment of the grid with 10 resolution was implemented and the system architecture and the plug-in facility were testified.
