Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes a computer, a DGPS, a gyro compass, an attitude sensor and an acoustic positioning device, and the DGPS, a gyro compass, an attitude sensor and an acoustic positioning device are connected to the computer. DGPS is used to send real-time location information based on the WGS-84 coordinate system to the computer, the gyro compass measures the detailed changes in the position of the ship, the attitude sensor is used to measure the changes in the attitude of the ship before and after the position, and the acoustic positioning device is used to measure the position of the underwater positioning object. For position information, in the present invention, an ultra-short baseline (USBL) is used. The reason why the ultra-short baseline is selected is that the integration price of the ultra-short baseline is low, and it is easy to install and realize, and has high measurement accuracy.

[0013] The present invention will b...

Abstract

The invention provides an integrated system for underwater positioning. The integrated system includes a computer, a DGPS, a gyrocompass, an attitude sensor and an acoustic positioning device, wherein the DGPS, the gyrocompass, the attitude sensor and the acoustic positioning device are connected to the computer. As a result of the technical scheme, the underwater land situation and landform can be intuitively and comprehensively evaluated, and later mapping is also facilitated.

Description

technical field [0001] The invention belongs to the field of positioning systems, in particular to a system for underwater positioning. Background technique [0002] At present, most marine projects, such as offshore oil and gas development and deep sea resource investigation, require acoustic positioning to track and locate underwater moving objects, such as divers and underwater remote control robots. Through the movement of divers and underwater remote control robots, we have a comprehensive understanding of the topography of the entire area to be investigated, but it is difficult to effectively combine the specific topography and exact location of the entire area, and it is difficult to synthesize these information later Processed for decision-making by staff. Contents of the invention [0003] The problem to be solved by the present invention is to provide a comprehensive system for underwater positioning, which is especially suitable for investigation of complex sea...
