| 摘 要： | RNP作为一种新的导航手段，其导航性能的评估是当前非常重要的研究课题。基于RNP飞行数据对侧向航迹偏差的计算方法进行研究，同时对近阶段短距离的经纬度坐标转化为平面直角投影坐标的转换方法进行探讨，从而提出近阶段实际航迹相对于定义航迹的侧向航迹偏差的计算方法，将为进一步统计分析及验证RNP导航性能提供很好的理论基础。

| Abstract: | As a new navigation means, RNP evaluation is a very important research subject currently. The lateral deviation calculation method based on RNP flight data is researched and the short distance coordinate conversion between geographical coordinate and plane rectangular coordinate in approach phases is discussed. Furthermore, a method to calculate the actual tract relative to the defined track is put forward for each phase. It can provide excellent theoretical basis for further analyzing and verifying RNP. |
