一种导航精度的综合评估表示方法

为了评估表示导航系统精度， 提出一种基于雷达图的综合评估表示方法， 包括速度、位置、姿态精度的评估表示。雷达图具有可视化的优点， 便于进行优劣分 析、综合评价，因此可以直观地将导航系统的精度表达出来。以捷联惯导系统和全球卫 星定位系统的组合导航系统精度对比分析为例进行研究，采用雷达图的方式取得了较好 的对比分析效果。将雷达图应用在组合导航系统的精度评估中，可简明直观地考核其精 度和性能，这为导航系统精度评估表示提供了一种有效的手段。

A Comprehensive Evaluation and Expression Method for Navigation Accuracy

In order to assess and express the accuracy of a navigation system, a comprehensive evaluation and expression method based on radar charts was proposed, the evaluation parameters of which included the accuracy of velocity, location and attitude. Radar charts have the advantages of visualization, which are convenient for quality analysis and comprehensive evaluation. Thus they can intuitively express the accuracy of the navigation system. The Integrated navigation system with Strapdown Inertial Navigation System (SINS) and Global Positioning System (GPS) was taken as an example to analyze its accuracy through comparison and good contrastive and analysis results were obtained by the method of radar charts. Radar charts were applied in the accuracy evaluation for the integrated navigation system, and this method was concise and intuitive to assess the accuracy and performance, which provided an effective means for the accuracy evaluation of the system.
