The aim of the presented research was to analyze the accuracy indications of three types of compass systems for the purposes of meeting warship modernization requirements. The authors of this paper have made an attempt to compare the accuracy of an onboard standard gyrocompass, a fiber-optic gyrocompass (FOG) and a satellite compass in real shipping circumstances.
Speed and latitude data are provided by sen- sors or entered manually via the Gyrocompass – An electrically-driven gyroscopic disc spinning at extremely high speed which keeps its relative axis in relation to space. Gyro failure : The Key words: magnetic compass, gyrocompass, magnetic compass total was a silent failure of the gyrocompass. Observed error should be recorded in the. Gyrocompass setting time at unknown meridian with max.
… - JG: Under application (Gyrocompass CMZ900) No. 4309 (Repeater compass MKR050) - MED: Under application - CCS: Scheduled Features: 1) A modular design saves the space. Master compass can be integrated in the autopilot steering stand. 2) Manual speed error correction 3) External heading sensor can back up the heading outputs. adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A A gyrocompass detects the true north by means of a fast-spinning rotor, which is suspended with no friction and is influenced by gravity and rotation of the Earth. A gyrocompass consequently indicates a ship's heading. CMZ900 series has been type approved in accordance with International Maritime Organization (IMO) standards, resolution The gyrocompass routine is a method of determining the direction of north (heading) utilizing a computer-controlled Inertial Measurement Unit (IMU).
The errors to which a gyrocompass is subject are speed error, latitude error, ballistic deflection error, ballistic damping error, quadrantal error, and gimballing error. Additional errors may be introduced by a malfunction or incorrect alignment with the centerline of the vessel.
The gyro compass also has other errors. This is the second half to the STCW assessement. Compass Errors Variation can be observed on any magnetic compass, whether or land away from any magnetic or on a ship at sea.

A gyrocompass is one of the most essential marine equipment on board now. Working under a simple physics law, it has changed how mariners navigate. Gyroscope needs to be maintained correctly for yielding accurate and precise results.

A gyrocompass having a gyro case housing a gyro with its spin axis being held substantially horizontal, a container surrounding the gyro case and containing a liquid therein, a first support device supporting the gyro case, a second support device supporting the container with three degrees of freedom, and a servo system causing the container to follow the gyro case about a vertical axis.
Can anyone offer an explanation. ERRORS OF THE GYRO COMPASS 1) Latitude ( or damping ) error This error is present in a compass which is damped in tilt.
Errors of the gyrocompass The total of the all the combined errors of the gyrocompass is called gyro error and is expressed in degrees E or W, just like variation and deviation.

The mercury-vessel gyrocompass is the more frequently used type of one-rotor gyrocompass. Use of each of these techniques, creates torque if the gyro axis is deviated from the plane of the horizon. A gyrocompass detects the true north by means of a fast-spinning rotor, which is suspended with no friction and is influenced by gravity and rotation of the Earth. A gyrocompass consequently indicates a ship's heading.
Gyro error When the gyro reading is higher than the true value, the error is termed as HIGH (to correct such error the error is subtracted to get the true reading) Similarly there is LOW. For example if ship is heading 000 degree true North and gyro is showing The compass error should be checked each watch and on every new course to measure the error of the gyrocompass, which is the angle the gyro north makes with the True north to establish trends in deviation on different courses at varying latitudes.This is important because should the gyro compass fail, this information will be needed to set courses using the magnetic compass. A gyrocompass is subject to certain errors. These include steaming error, where rapid changes in course, speed and latitude cause deviation before the gyro can adjust itself. On most modern ships the GPS or other navigational aids feed data to the Gyro Compass Error And Correction The current should be about 1.25 to 2.25 amperes. Once the axis points toward the celestial pole, it will appear to be stationary and won't experience any more frictional forces. The observed motion, precession, is always about an axis at a right angle to the axis of the impressed force.
