高质量的CPNT是深海潜水器潜入深海、探测和开发深海的关键技术。然而，目前，CPNT为深海航行器提供的服务是由单独的通信、定位和导航系统以及单独的同步时钟（原子钟）提供的。这直接影响到深海科学研究、环境调查和资源开发等深海航行器的运行效率，例如更新率高达0.125 Hz。为此，本文提出了一种新的CPNT设计方法和工作模式，以克服目前深海航行器通信/定位/导航模式的固有缺陷，满足深海航行器真实的实时性的实际需求，实现高更新率、低功耗、高精度的定位和导航，并与当前的发展趋势相结合。CPNT的集成既可以统一时间和空间基准，又可以降低多传感器信息融合的难度。从而从根本上解决了深海航行器导航性能差、无计时功能的问题。CPNT的集成将提高大型深海航行器的导航和定位精度以及信息更新速率（高达1 Hz），如深海载人潜水器，深海遥控水下航行器和深海自主水下航行器。
High-quality CPNT is a key technology for deep-sea vehicles that dive into the deep sea and for detecting and developing the deep sea. At present, however, CPNT services for deep-sea vehicles are provided by separate communication, positioning, and navigation systems as well as separate synchronous clocks (atomic clocks). This directly affects the operational efficiency, for example, update rates of up to 0.125 Hz, of deep-sea vehicles engaged in deep-sea scientific research, environmental investigation, and resource development. Therefore, a new design method and operating mode of CPNT is proposed herein to overcome the inherent flaws of the current communication/positioning/navigation modes of deep-sea vehicles; meet the actual demands of deep-sea vehicles in real time; achieve high update rates, low power consumption, and high precision positioning and navigation; and to be combined with the current development trends. The integration of CPNT can both unify time and space references, and reduce the difficulty of multi-sensor information fusion. Thus, the problems of poor navigation and the non-timing functions of deep-sea vehicles can be solved fundamentally. The integration of CPNT will improve the navigation and positioning accuracy as well as the information update rate (up to 1 Hz) of large deep-sea vehicles, such as deepsea human-occupied vehicles, deep-sea remotely operated underwater vehicles, and deep-sea autonomous underwater vehicles.
