飞机导航系统校准技术探讨

飞机导航系统是引导和保障飞机安全飞行的关键系统，其所涉及的一些主要参数（如VOR方位、TACAN方位、进近着陆距离、下滑轨迹等）是典型的专用参数，采用普通的方法很难准确地校准这些参数，同时由于缺少直接的国家（国防）最高标准，溯源也很困难。本文以区域导航系统为例，就其校准系统发展的特点、现有校准方法的优缺点、现有计量技术的瓶颈及解决设想等方面做些探讨性的研究，以期能够更好地解决现有军（民）机导航系统专用计量参数的溯源和量传中存在的问题。

Exploring of How to Calibrate Airplane's Navigation System

The navigation system,which is one of the most important parts of the airplane,can keep the airplane flying safely.But,some parameters of the system,such as the VOR bear,TACAN bear,landing distance and slip line etc,are special parameters which are difficult to calibrate accurately by the common ways.In addition,it is also difficult to be traced to the national standard directly for lack of the highest national standard.Now,we take the Range NAV system for an example to research the characteristics of the c...
