METHOD FOR CHECKING THE ACCURACY OF NAVIGATION OF AN AUTONOMOUS UNINHABITED UNDERWATER VEHICLE Russian patent published in 2023 - IPC G01S3/80 

FIELD: shipbuilding.

SUBSTANCE: invention relates to field tests of autonomous uninhabited underwater vehicles and can be used to verify the accuracy of their navigation and trajectory capabilities of underwater movement, which largely determine the scope of application of underwater vehicles and the category of tasks solved with their help. Essence: in the claimed method for checking the accuracy of navigation of an autonomous uninhabited underwater vehicle due to the possibility of operational visual control of the two-dimensional trajectory of its underwater movement, transposed to the surface of the water area of the test site, in the process of checking the possible trajectories of its movement and reducing the time of post-processing of trajectory data when checking the accuracy of navigation as a result of coordinated movement along the two-dimensional trajectory of the programmed route in the water area of the test site of an autonomous uninhabited underwater vehicle and an unmanned surface vessel performing the functions of a navigation beacon and a surface indicator of the two-dimensional trajectory of underwater movement of an autonomous uninhabited underwater vehicle, with a record on an unmanned surface vessel of its current geodetic coordinates and diving depths of an autonomous uninhabited underwater vehicle on the route of movement, used in post-processing of trajectory data to plot the trajectory of the route of an autonomous uninhabited underwater vehicle in the water area of the test site.

EFFECT: expanding the functionality and increasing the efficiency of the single-beacon navigation method during testing of an autonomous uninhabited underwater vehicle at a marine test site.
