摘要:

为满足部队和大修厂对航空无线电近距导航系统的检测需求，设计了以PC104嵌入式计算机为核心的自动检测仪硬件与软件程序，详细阐述了主要功能模块的工作原理。采用高精度的恒温晶振源，通过延时电路模拟地面信标产生方位、距离模拟信号以检测机载设备的导航精度及抗噪性能，其检测精度达到001PPM。

Abstract:

To meet the checking requirement of aviation radio ShortRangNavigation s ystem in military and overhaul works,the hardw are and software of checkup equipment are designed based on PC104 embedded com puter, and the functions of major parts are illustrated in detail. The co nsta nt temperature oscillator source is adopted and the orientation and distance sig nals are generated through the way of delayed circuit simulating ground radio b eaconing to detect the navigation p recision and resistance performance to noise. The detection precision can reac h 0.01PPM.
