DME是一种通过询问应答的方式为飞行员提供飞机到地面站距离指示的距离测量设备,用于飞机整个航行阶段.而DME/DMERNAV是一种至少利用两台DME共同工作实现在区域导航航线上授权使用的导航方式.为了准确判别DME/DME的运行是否满足我国区域导航航线授权运行规范,优化选择地面DME台站,通过建立水平定位精度模型和运行精度模型,采用加权最小二乘算法分别对DME/DME的水平定位精度和RNAV三种常用运行方式的定位精度进行了仿真分析,通过仿真给出了影响DME/DMERNAV运行精度的两个重要因素,DME测距精度和两DME台站内夹角,为RNAV飞行管理系统选取满足RNAV运行规范DME和台站切换提供了可靠的判决依据.
The DME is a distance measuring device that provides pilots with an indication of the distance from the aircraft to the ground station by means of an interrogation response, which is used for the entire flight phase of the aircraft. The DME / DMERNAV is a DME / DMERNAV that uses at least two DMEs to work together on a regional navigation route In order to accurately determine whether the operation of DME / DME meets the authorization of China’s regional navigation routes and optimize the selection of terrestrial DME stations, a horizontal positioning accuracy model and a running accuracy model are established, and weighted least squares DME / DME horizontal positioning accuracy and RNAV three common operating mode of the positioning accuracy of the simulation analysis is given through the simulation DME / DMERNAV operating accuracy of the two important factors, DME ranging accuracy and DME station angle , Which provided a reliable basis for RNAV flight management system selection to meet the requirements of RNAV operation standard DME and station switching.
