浅谈深拖作业中双船定位的技术优势

摘要

Two working ships are used in deep towing operation, one for tracking and positioning, and the other for deep towing. The positioning of deep towing object is mainly by the ultra-short baseline acoustic positioning system installed in the side of the tracking and positioning ship combined with DGPS positioning system. Through the analysis of the characteristics of the ultra-short baseline positioning, and combined with practical application cases, this paper explains the technical advantage of double ship operation in deep towing.%在深拖作业中采用两条工作船，其中一条为追踪定位船，另一条为深拖拖曳船。深拖拖体的定位主要靠安装在追踪定位船侧舷的超短基线声学定位系统结合DGPS定位系统的方式对水下拖体进行定位。通过对超短基线定位特性的分析，并结合实际应用的案例，解释了深拖作业中采用双船作业的技术优势。
