The invention relates to a long baseline shipborne positioning device and a positioning method thereof. The shipborne positioning device comprises an underwater acoustic communication module and a data processing module; the underwater acoustic communication module is respectively connected with a positioning array and the data processing module and is used for sending an underwater acoustic instruction to the positioning array, receiving a response signal returned by the positioning array and sending the received response signal to the data processing module; and the data processing module isused for acquiring DGPS, attitude and sound velocity information of a ship body, calibrating and correcting the ship body position and the sound velocity when the underwater sound instruction and theresponse signal are sent according to the DGPS, the attitude and the sound velocity information, resolving the response signal received by the underwater sound communication module, and obtaining theposition information of the positioning array or the seabed response equipment. According to the embodiment of the invention, adverse effects caused by ship body position errors are avoided, and theintegration level and compatibility of the shipborne positioning device are improved while the positioning precision is improved.
Description
technical field [0001] The present application belongs to the technical field of underwater positioning, and in particular relates to a long baseline shipboard positioning device and a positioning method thereof. Background technique [0002] Due to its large range of action and high positioning accuracy, the long baseline positioning system has been widely used in many aspects such as marine resource development and national defense construction. The baseline array is generally composed of four or more base arrays. The distance between the target and each base array is obtained by measuring the time delay difference between the positioning target and the query response between each base array, and the target positioning is completed by measuring the rendezvous. [0003] The positioning accuracy of the base array directly affects the accuracy of the entire positioning system. As the core part of the long baseline positioning system, the shipborne positioning system is respon...
