What is the main system under the control of the master gyro?
It is driven thousands of revolutions per minute by another electric motor. However, the most essential part of a Gyro compass system is the spinning wheel, which is known as the Gyroscope.
What is principle of gyro compass?
The operation of the gyro compass depends on four phenomena: (1) gyroscopic inertia which enables the rotor to maintain the direction of its plane of rotation unless an external force of sufficient amplitude alters its direction; (2) gyroscopic precession which causes movement at 90° to any applied force; (3) gravity; …
What is the importance of gyro compass?
The gyrocompass was an important invention for nautical navigation because it allowed accurate determination of a vessel’s location at all times regardless of the vessel’s motion, the weather and the amount of steel used in the construction of the ship.
Where is Master gyro compass located on ship?
The gyrocompass is typically located on the wheelhouse as close as possible to the center of roll, pitch and yaw of the ship, thus minimizing errors caused by the ship’s motion.
What is master compass?
[′mas·tər ′käm·pəs] (navigation) That part of a remote-indicating compass system which determines direction for transmission to various repeaters.
What is gyro compass repeater?
gyro repeater in American English (ˈdʒairou) a navigational compass, under the control of a gyroscope, that automatically indicates true north. Also called: repeater.
What is the difference between the master gyro compass and the gyro compass repeater?
Master Gyro Compass: Discovers and maintains the true north reading with the help of gyroscope. Repeater Compasses: Receive and indicate the true direction transmitted electrically from the Master Compass.
What is the working principle of magnetic compass?
The magnetic compass is working with the principle of Earth’s Magnetic Field and shows the magnetic north and south. The simplest form of compass consists of a magnetized needle free to rotate in a horizontal plane. Such a needle tends to settle in the magnetic meridian.
Who invented gyro compass?
Elmer Ambrose SperryGyrocompass / Inventor
How is gyro compass made north seeking?
It is made north-seeking by placing a weight below the spinning axis as shown in Figure 17-11. Let us assume that the gyroscope is at the equator with its spinning axis horizontal and pointing to the east of the meridian.
What are the parts of gyro compass?
A modern gyrocompass unit consists of a master unit, a control cabinet, a power supply unit a speed unit, and auxiliary electrical transmission and alarm units.
What are the methods of determining the errors of gyro compass?
Standard books on navigation describe several methods for determining the compass error — by reciprocal bearings, requiring a station on shore; by bearings of the sun, requiring a clear day; by ranges, requiring that the magnetic bearing of the range be known; and by a distant object, requiring the object to be at a …
