摘要： 针对深海中微子望远镜探测舱水下定位需求，提出一种多目标水下定位策略，即对中微子望远镜线缆阵列定位模块进行分组，基于5基站定位系统，进行两组线缆的相互定位。此外，基于实验数据建立中微子望远镜探测舱的水声定位仿真方法,对水下定位策略的精度进行分析。仿真结果表明：随着定位距离增加，中微子望远镜探测舱空间坐标的误差增大；与3基站定位策略相比，5基站定位结果的误差平均值降低80.15%，5基站定位策略有助于定位精度的提升。研究成果可以为深海中微子望远镜水下定位系统提供理论支撑与新的解决方案。

Abstract: To meet the underwater positioning requirements of detection modules in deep-sea neutrino telescope, a multi-target underwater positioning strategy is proposed, that is, the positioning module of neutrino telescope string array is grouped, and the two groups of strings are positioned each other based on the five-station positioning system. In addition, based on the experimental data, the underwater acoustic positioning simulation method of the neutrino telescope detection module is established, and the accuracy of the underwater positioning strategy is analyzed. The simulation results show that the error of space coordinates of the neutrino telescope detection module increases with the increase of positioning distance. Compared with the three-station positioning strategy, the average error of the five-station positioning results is reduced by 80.15%, and the five-station positioning strategy is helpful to improve the positioning accuracy. The research results can provide theoretical support and new solutions for the underwater positioning system of the deep-sea neutrino telescope.

Key words: deep-sea neutrino telescope, multi-target underwater positioning strategy, underwater acoustic positioning simulation method, underwater acoustic positioning accuracy
