摘　　要：DME是一种国际公认的高精度近程测距导航系统,主要作用是为飞机机载接收机提供应答信号,经机载接收机解调后测出地面信标台相对于飞机的斜距,可与DVOR组合成地理局部极坐标定位导航系统。虽然INDRA LDB-102型DME测距设备在全国空管已逐步淘汰,但它作为地方机场ILS NM7000B仪表着陆系统配套的测距设备,还将继续使用很长一段时间。该设备的总体特点是集成度不高但性能可靠,故障率低。文章对LDB-102型DME设备的几起非典型故障的排查、维修进行简述,供同行探讨。DME is an internationally recognized high-precision short-range ranging navigation system.Its main function is to provide a response signal for the airborne receiver.After demodulation by the airborne receiver,the oblique distance of the ground beacon station relative to the aircraft can be measured,which is based on DVOR to form a geographical local polar positioning and navigation system.Although the INDRA LDB-102 DME ranging equipment has been gradually eliminated in the national air traffic control,it will continue to be used for a long time as the ranging equipment for the local airport ILS NM7000B instrument landing system.The overall characteristic of the equipment is that the integration is not high,but the performance is reliable and the failure rate is low.This paper briefly describes the troubleshooting and maintenance of several atypical faults of LDB-102 DME equipment for discussion.
