Dynamic Positioning Device (System 2)
Dynamic Positioning Device (System 2)

A device that ensures the research vessel maintains its position so that researchers may conduct their research, even in poor weather, using ROV or exploration equipment 6,000 meters underwater.
The system consists of two main propellers at the stern of the vessel, a pump-jet thruster, a retractable thruster at the bow, a DGPS system, and three types of sensors for measuring wind direction, wind velocity, and the movement of the vessel.

Satellite Navigation System
Satellite Navigation System

The research vessel acquires information on its position using DGPS (Differential GPS), which is accurate to within one meter. The navigation system employs the pseudorange correction method, in which distance errors are detected and corrected to estimate the position of the vessel, using time and orbital data communicated via satellite from the reference station.
During navigation or exploration, this system guides the research vessel to the exploration site. The mounted equipment then links the vessel’s position to motion sensors and contributes to enhancing the accuracy of the observed positioning data by correcting for the differences in positioning information from three-dimensional coordinates and positioning data that have been precisely measured on land in advance.
An all-weather global positioning system that provides highly accurate locational information, this system allows the vessel to determine its position anywhere in the world.

The information collected by the multibeam echo sounder is transmitted to a computer onboard the vessel, which then produces a bathymetric map or a contour map with relevant colors and graphics in real time. The data gained from each ping is separated into different types of information, and the device can take measurements down to a depth of 11,000 meters underwater.
