A Long Baseline Time Scale Positioning Array and Its Control Method

Abstract

The present application relates to a long baseline time scale positioning array and a control method thereof. The matrix includes a self-floating and dumping mechanism, a first cabin ball, a second cabin ball and a bottom anchor; the first cabin ball is installed above the second cabin ball, and the top of the first cabin ball It is connected with the self-floating dumping mechanism, the bottom of the second cabin ball is connected with the bottom anchor seat, and the self-floating dumping mechanism is connected with the bottom anchor seat; the first cabin ball includes an underwater acoustic communication module , used to send the positioning information of the submarine response equipment to the shipborne acoustic device; the second cabin ball includes an atomic clock master control circuit and an underwater acoustic emission circuit, used to transmit a clock synchronization signal to the submarine response equipment. The embodiment of the present application can meet the requirements of large water depth and long-time work, and use its own high-precision atomic clock to provide high-precision clock synchronization signals for underwater equipment, which solves the problem of internal clock instability caused by long-time underwater equipment due to the influence of ambient temperature caused by clock skew.

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.
