Embodiment Construction
[0025] The experimental methods used in the following examples are conventional methods unless otherwise specified.
[0026] The materials and reagents used in the following examples can be obtained from commercial sources unless otherwise specified.
[0027] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
[0028] Such as figure 1 As shown in Fig. 1, the construction ship uses the tugboat to throw multiple anchor cables around to fix the ship. In this way, the horizontal stability of the hull during operation can be basically guaranteed. The transducer (Tcvr) in the ultra-short baseline hydroacoustic positioning system is installed on the outer side of the stern, along the vertical direction of the deck of the hull, with the intersection of the plane where the transducer and the deck are located as the origin, the hull coordinate system is established. ...
