Embodiment 1

[0025] Such as Figure 1-7 As shown, the embodiment of the present invention provides a deep-water high-precision navigation and positioning technology based on multi-method fusion, including an underwater acoustic positioning system, an inertial navigation system, a map matching positioning system, and a multi-sensor data fusion positioning system. Inertial navigation system, map matching positioning system and multi-sensor data fusion positioning system are connected and fused. Before use, the inertial navigation system needs to be preliminarily corrected by Doppler log and pressure sensor. The underwater acoustic positioning system consists of array, Composed of transducers and underwater transponders, underwater positioning can be performed by measuring the propagation time or phase difference of the acoustic signal. The information measured by the underwater acoustic positioning system can be used as an input for information fusion and provide a source for the cumulative e...

Abstract

The invention provides a deepwater high-precision navigation positioning technology based on multi-method fusion, and relates to the technical field of deep sea detection. The deepwater high-precision navigation positioning technology based on multi-method fusion comprises an acoustic positioning system, an inertial navigation system, a map matching positioning system and a multi-sensor data fusion positioning system, and the acoustic positioning system, the inertial navigation system, the map matching positioning system and the multi-sensor data fusion positioning system are connected and fused. Before use, the inertial navigation system needs to be preliminarily corrected through a Doppler log and a pressure sensor, and the underwater acoustic positioning system is composed of an array, a transducer and an underwater transponder. Through multi-method fusion, underwater navigation can overcome the influence of a deepwater environment, the reliability of navigation positioning is improved, the efficient, high-precision and high-reliability underwater navigation positioning is realized through an information fusion method, and an underwater robot is guided to complete various complex tasks.

Description

technical field [0001] The invention relates to the technical field of deep-sea detection, in particular to a deep-water high-precision navigation and positioning technology based on multi-method fusion. Background technique [0002] Navigation and positioning technology occupies an important position in the deep sea detection technology system, which directly reflects the accuracy and safety of underwater operations. With the continuous development of deep-sea exploration technology, underwater navigation and positioning technology is also constantly improving, and technologies such as inertial navigation, acoustic navigation, and marine geophysical navigation have been continuously applied and improved. [0003] The update rate of inertial navigation data is high, the delay of navigation information is low, and the system is stable and not easily disturbed, and the accuracy of navigation and positioning is high in a short period of time. However, with the increase of time...
