具有声学导航定位系统的无人无缆潜器在水下构件中航行时会遇到声场、磁场干扰的麻烦。本文从分析水声通讯可靠性入手,说明辅助定位系统的必要性;结合所介绍潜器的特点,提出了一种既简单、又经济的辅助定位系统方案。
An unmanned cableless submarine with an acoustic navigation and positioning system encounters the problem of sound field and magnetic field interference when navigating underwater components. This article starts with the analysis of the reliability of underwater acoustic communication and explains the necessity of the auxiliary positioning system. Combining the characteristics of the introduced submarine, a simple and economical auxiliary positioning system is proposed.
