The installation error in a highly precise USBL can not to be ignored before its actual application. 高精度超短基線定位系統的安裝誤差影響不可忽視，需要在使用前進行精確校準。
Because of the special bucket foundation constructure, it is difficult to measure the bucket foundation installation error by using transit. 根據桶形基礎的特殊形式，採用普通經緯儀對桶基安裝誤差進行測量是比較困難的。
According to the experiment this method is less impacted by light and floor circumstance, less error of aberrancy, better real-time and robustness. 實驗表明此方法獲取的導航參數受光照和地面環境的影響不大，且偏離導航線誤差較低，具有較好的實時性和魯棒性。
