Abstract

The invention relates to a long baseline time scale positioning array and a control method thereof. The array comprises a self-sinking and self-floating load rejection mechanism, a first cabin ball, asecond cabin ball and a bottom anchor seat. The first cabin ball is installed above the second cabin ball, the top of the first cabin ball is connected with the self-sinking and self-floating load rejection mechanism, the bottom of the second cabin ball is connected with the bottom anchor seat, and the self-sinking and self-floating load rejection mechanism is connected with the bottom anchor seat. The first cabin ball comprises an underwater acoustic communication module and is used for sending positioning information of seabed response equipment to a shipborne acoustic device; and the second cabin ball comprises an atomic clock main control circuit and an underwater acoustic emission circuit and is used for emitting a clock synchronization signal to the seabed response equipment. According to the embodiment of the invention, the requirements of large water depth and long-time work can be met, the high-precision atomic clock is used for providing a high-precision clock synchronization signal for the underwater equipment, and the problem of clock skew caused by instability of an internal clock due to the influence of the environment temperature on the underwater long-time work equipment is solved.

Description

technical field [0001] The application belongs to the technical field of underwater positioning, and in particular relates to a long baseline time scale positioning array and a control method thereof. Background technique [0002] With the development of science and technology and the demand for energy, people have developed and utilized more and more marine resources in recent years. Underwater positioning technology provides a basic guarantee for marine development and scientific research. The long-baseline time-scale positioning array is widely used in deep-water positioning due to its characteristics of a baseline length of 100m-6000m, high positioning accuracy, and a large working range. The long baseline time scale positioning base array usually consists of more than three base arrays and an acoustic response device installed on the positioned target. difference, get the mutual distance, and finally solve the location information of the positioned target. [0003] As...
