Embodiment 1

[0025] Such as figure 1 As shown, a manned submersible long baseline positioning system underwater submersible mark array optimization method, including the following steps:

[0026] The first step is to detect the water depth and drive the mother ship to an area with an ocean depth of about 5,000 meters;

[0027] The second step is to lock the latitude and longitude of the mother ship and record it;

[0028] The third step is to launch the beacon, including the following small steps:

[0029] ① Release 1# beacon, record the latitude and longitude, detect the depth of sea water during the release process and record the final depth;

[0030] ② At a distance of 2km-3.5km from the 1# beacon, release the 2# beacon, record the latitude and longitude, detect the depth of the seawater during the release process and record the final depth;

[0031] ③In the direction perpendicular to the connection line between 1# beacon and 2# beacon, place 3# beacon at a distance of 2km-3.5km from...

Embodiment 2

[0042] The first step is to recycle 1#, 2#, 3#, 4#, take the 1# beacon as the origin, re-release the beacon in the rectangle formed by the beacon, and rotate it at a certain angle.

[0043] The second step is to launch the beacon, including the following small steps:

[0044] ① Release 1# beacon, record the latitude and longitude, detect the depth of sea water during the release process and record the final depth;

[0045] ② At a distance of 2km-3.5km from the 1# beacon, release the 2# beacon, record the latitude and longitude, detect the depth of the seawater during the release process and record the final depth;

[0046] ③In the direction perpendicular to the connection line between 1# beacon and 2# beacon, place 3# beacon at a distance of 2km-3.5km from 2# beacon, record the latitude and longitude, detect the depth of seawater during the launch process and record the final depth;

[0047] ④ Put the 4# beacon at the symmetrical position of the 1# and 3# connection lines of ...

Embodiment 3

[0057] The first step is to recycle 1#, 2#, 3#, 4#, take point O as the origin, transform the rectangle into a triangle and launch the beacon again;

[0058] The second step is to launch the beacon, including the following small steps:

[0059] ① Release 1# beacon, record the latitude and longitude, detect the depth of sea water during the release process and record the final depth;

[0060] ② At a distance of 2km-3.5km from the 1# beacon, release the 2# beacon, record the latitude and longitude, detect the depth of the seawater during the release process and record the final depth;

[0061] ③In the direction perpendicular to the connection line between 1# beacon and 2# beacon, place 3# beacon at a distance of 2km-3.5km from 2# beacon, record the latitude and longitude, detect the depth of seawater during the launch process and record the final depth;

[0062] ④ Put the 4# beacon at the symmetrical position of the 1# and 3# connection lines of the 2# beacon, record the latitu...

Abstract

The invention relates to the technical field of ocean detecting, in particular to an underwater submerged buoy formation optimization method of a manned submersible vehicle long base-line positioning system, and aims to provide a submerged buoy formation guaranteeing that precise testing data is obtained in deep sea testing and provide a high-precision positioning service to subsequent submersible vehicles. The method includes: allowing a mother ship to travel to an area with the ocean depth of about 5000 meters; locking the longitude and latitude of the mother ship and recording, and placing beacons; allowing the mother ship to travel to the diagonal intersection of the rectangle formed by the beacons; releasing submersible vehicles, and allowing the connecting line of three travelling directions of the submersible vehicles to be located at the center of the four edges of the rectangle. By the submerged buoy formation optimization method, the foundation of testing data accuracy in deep sea testing is laid, reference is provided to the long base-line testing in deep sea testing, and evident advancement is achieved.
