摘要
实际导航性能(ANP)作为基于性能的导航(PBN)的重要参数,反映了飞机实时位置的误差估计,决定飞机是否能够满足所需导航性能(RNP)的要求,对ANP的性能质量分析是实施RNP的关键技术。本文提出了利用导航位置不确定度(NUCp)来评估ANP性能质量的方法,利用NUCp正态性的检验,对NUCp报告误差进行矫正,最后利用NUCp统计特性计算,结合最小二乘法计算ANP数值,结果证明,该方法计算量小,能准确估计实际导航性能。
The actual navigation performance(ANP)is an important paramete of performance based navigation(PBN),the estimation error of real-time aircraft position response,determine whether the aircraft can meet the required navigation performance(RNP)requirements,performance and quality analysis of ANP is the key technology of implementing RNP.This paper presents the using the navigation uncertain category for position(NUCp)to evaluate the quality of the performance of ANP method,using the NUCp normality test,the NUCp report error correction,finally using NUCp statistical characteristics calculation,combining with least square method,ANP numerical calculation,results show that the method has small amount of calculation,can accurately estimate the actual navigation performance.
