Abstract

The invention provides a deep sea underwater sound integrated positioning system and a method for positioning and navigating an underwater vehicle by adopting the system, and belongs to the field of underwater sound positioning sonar equipment. According to the deep sea underwater sound integrated positioning system and the method for positioning and navigating the underwater vehicle by adopting the system, an acoustical transducer receiving and transmitting array is arranged at the tail end of an array lifting rod, the input / output end of the acoustical transducer receiving and transmitting array is connected with the output / input end of a tracking and calibrating processor which is connected with an operation and display platform, an inner cavity of a deep water pressure-resisting shell is an electronic distance measuring and positioning cabin, a deep water pressure-resisting transducer is electrically connected with the electronic distance measuring and positioning cabin through a pressure-resisting watertight cable, an electronic response release management cabin is arranged on the inner side of the deep water pressure-resisting shell, a battery pack is fixed in the electronic response release management cabin, a release mechanism is fixed at the tail of the outer side of the deep water pressure-resisting shell, and the deep water pressure-resisting transducer is fixed at the top end of the outer side of the deep water pressure-resisting shell.According to the deep sea underwater sound integrated positioning system and the method for positioning and navigating the underwater vehicle by adopting the system, the position of an underwater target is monitored in real time on the water surface, and full-sea-depth positioning accuracy is improved by more than four times compared with existing equipment.

Description

Technical field [0001] The invention belongs to the field of underwater acoustic positioning sonar equipment, and relates to a deep sea acoustic integrated positioning system and a positioning and navigation method for underwater vehicles. Background technique [0002] The 21st century is the "Ocean Century", and the ocean, a treasure house of huge resources, has received increasing attention from all countries. In the past 20 years, the "circle sea movement" that competes for maritime sovereignty and seabed mineral resources has emerged, prompting my country's marine industry to enter a stage of rapid development, and also pushing technologies and equipment related to marine development into the fast lane of development. Acoustic positioning is an indispensable method for marine scientific surveys, marine resource exploration, marine resource development, and deep-sea space station construction. It can provide important positioning, navigation and communication support for subse...
