Research Vessel OverviewR/V ISABU
“Isabu” was named after General Isabu of the Silla Dynasty, who conquedred the nation of Usan-guk, which occupied present-day Ulleungdo Island, and incorporated it into Korea. This name was given to the research vessel to signify KIOST’s adventurous spirit, akin to that of General Isabu, and dedication to expanding its influence in the area of marine science in order to help Korea become a leader in the global maritime community.

R/V IsabuNavigation and Communication Equipment
The room from which the crew supervises and guides the operation of the ship.
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.
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.
A system that detects and locates an object by emitting radio waves toward and receiving radio waves from the object.
Satellite communication refers to communication or other transmissions of media conducted via satellites deployed at certain orbital altitudes. On research vessels, satellite communication equipment provides communication and weather information necessary for navigation.
A device for receiving weather information necessary for navigation while a vessel is at sea.
A device that measures the speed of a vehicle. On vessels, speedometers measure and indicate the speed of the vessel relative to the water.

An information system that allows for the easy and prompt recognition of the geography of the surrounding area and indicates the vessel’s position on an electric chart, which has replaced paper charts.
An instrument capable of measuring the depth of water while a vessel is stationary or in motion.
A GPS and motion system that provides accurate, real-time locational information for the research vessel and the mounted research equipment it operates. It also corrects the vessel’s attitude data. For higher accuracy, the system uses DGPS (Differential Global Positioning System), based on which it receives GPS signals from satellites and signals from groundbased reference stations through beacon receivers, allowing for the correction of positioning errors.
R/V IsabuResearch Equipment
Devices that emit sound waves from a blister-type acoustic sensor mounted on the bottom of the vessel as a means of observing and recording water depth and the geography of the seabed. Unlike single-beam echo sounders, which can take measurements at only a single location immediately below the vessel, multibeam echo sounders produce a swath of depth measurements and readings within the sound wave emission and reception range of the device. 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.

Marine gravity meters are used to measure gravity on vessels at sea. These meters are equipped with anti-shock instruments on the four corners of the device to minimize the influence of the motion of the vessel.
