As for the safety of bridge construction, it is necessary to guarantee the design line of the bridge, but the positioning precision with guyed travelers is the most important. 橋樑安全性能如何，施工能否保證橋樑的設計線型是關鍵，而掛籃的定位精度是保證線型的首要前提。
The computer simulation results obtained and real data analysis indicate that a GCC TDE method can ensure high estimation precision when it is used in passive localization systems. 計算機模擬結果和湖試數據分析表明，將廣義相關時延估計法應用於被動定位系統可以獲得較高的定位精度。
