The invention relates to a towed towed buoy array positioning device and method. The towed towed buoy array positioning device comprises a towed mother ship, and a deck unit is fixedly installed on the towed mother ship; the system further comprises a plurality of dragging buoys which are connected in series through ropes and form a dragging buoy array, the dragging buoy located at the foremost end is connected with the dragging mother ship through the rope, and the whole dragging buoy array is dragged by the dragging mother ship on the water surface to sail. The dragging buoy located at the tail end is arranged in a transverse offset mode, complex installation and calibration are not needed before use, and laying and recycling are convenient; the acoustic measurement sensor is always kept far away from a mother ship and is less interfered by ship body noise, so that the acoustic positioning calculation precision is greatly improved; according to the device, accurate positioning of deep towing is achieved based on the spatial distance intersection positioning principle, the base line of the acoustic measurement sensor array is long, the accuracy advantage of long base line positioning is achieved, no positioning tracking ship is arranged in the method, and compared with a double-ship positioning method, the manpower and material resource cost is reduced through the method.
本发明涉及一种拖曳式拖曳浮标阵定位装置及定位方法,包括拖曳母船,所述拖曳母船上固定安装有甲板单元;还包括多个用绳索串联连接的拖曳浮标,并组成一个拖曳浮标阵,位于最前端的拖曳浮标通过绳索与拖曳母船相连,整个拖曳浮标阵由拖曳母船在水面拖带航行;位于最末端的拖曳浮标横向偏移设置,使用前无需进行复杂的安装校准,布放及回收也较为方便;声学测量传感器离母船始终保持较远的距离,受船体噪声干扰较小,极大提高了声学定位解算精度;该装置基于空间距离交汇定位原理实现深拖的精确定位,声学测量传感器基阵的基线较长,有着长基线定位的精度优势,方法不再配备定位跟踪船,相较于双船定位方法,本方法减少了人力物力成本。
