机载设备已由针对单一地面台工作转变为可针对多地面台工作,如测得距3个地面台的斜距P,利用P—P—P定位方法,可进行定位和导航计算,这种多地面台扫描工作体制将成为DME发展的趋势。结果表明,该系统能够实现多台链工作,性能稳定可靠。
機載設備已由針對單一地麵檯工作轉變為可針對多地麵檯工作,如測得距3箇地麵檯的斜距P,利用P—P—P定位方法,可進行定位和導航計算,這種多地麵檯掃描工作體製將成為DME髮展的趨勢。結果錶明,該繫統能夠實現多檯鏈工作,性能穩定可靠。

Airborne Equipment has transformed from working for a single ground station to working for multi ground stations. If the slant-range P from 3 ground stations are measured, positioning and navigation can be a- chieved by the P-P-P positioning method. This multi ground stations scanning mechanism will be the developmenttrend of DME. It is shown that this system can realize multi chain work and its performance is reliable.
