問題一覧

A navigational instrument that shows the rate at which a vessel is turning, typically in degrees per minute. This helps maintain a steady and controlled course.

Rate of turn indicator

A device that displays the angle of the ship’s rudder relative to its centerline, helping the helmsman and officers monitor and control the ship's steering.

Rudder Angle Indicator

A safety system that monitors bridge activity to ensure the officer on watch is alert. It sounds alarms if the officer fails to respond within a set time.

BNWAS

Often referred to as a "black box" for ships, the VDR records essential navigational data, including voice communications on the bridge, for analysis in case of an incident

Vdr

A tracking system that automatically provides the position, course, speed, and identification of ships to nearby vessels and coastal authorities, improving collision avoidance.

Ais

A computer-based navigation system that displays electronic nautical charts and integrates real-time position data, helping to ensure safe navigation.

Ecdis

A global tracking system mandated by the IMO that provides continuous tracking of a ship’s position over long distances for security and safety purposes.

Lrit

A radar feature that automatically acquires and tracks targets, providing information about their speed, course, and closest point of approach, improving situational awareness.

ARPA

A navigational aid that uses radio waves to detect objects like ships, land, and obstacles, helping to avoid collisions and safely navigate in low-visibility conditions.

Radar

A compass that finds true north based on the rotation of the Earth rather than magnetic north, offering more reliable directional information for navigation.

Gyro Compas

A device that measures water depth by sending sound waves to the seabed and timing how long they take to return, used to prevent grounding and measure underwater terrain.

Echo Sounder

A system that allows the crew inside the enclosed bridge to hear external sounds, like fog signals or alarms, improving situational awareness.

Sound Reception System

A tool that measures a ship’s speed through water or over the ground and records the distance traveled, crucial for accurate navigation.

Speed and Distance Log Device

Lights on a ship used during the night or in poor visibility to signal the vessel's position, size, direction of travel, and activity (e.g., anchored, under sail, or power).

Navigational Lights

A system that automatically steers the ship along a pre-set course without constant manual input from the helmsman, improving operational efficiency.

Autopilot

A satellite-based navigation system that provides real-time information on a ship’s precise location, speed, and direction anywhere on Earth.

GPS

An angular measurement used in navigation and astronomy to determine the direction of an object or celestial body from the observer. It is the angle between a reference direction (usually true north) and the line from the observer to the object, measured clockwise from 0° to 360°. Azimuth is used to specify the exact direction of an object relative to a given point.
