Gyro fail in Singapore strait. Gyro compass failure and action Effect of gyro fail in Singapore strait:Malfunction of any connected equipment.Gyro repeater will not work.Auto pilot will not work.AIS will not show correct heading.VDR will not record correct heading.Radar picture change. Target course speed change.ECDIS malfunction. Equipment that can be affected:Gyro repeater, Auto pilot, AIS, … Read moreGyro fail in Singapore strait. Gyro compass failure and action

Difference between Anschutz and Sperry gyro Sperry Gyro:Top heavy and Damping in tilt.All top heavy weight control gyro must rotate anticlockwise when viewed from South.To get Damping in tilt, torque (horizontal force) is applied about vertical axis.Damping in tilt is applied – when north end of spin axis moves out of horizontal.Damping in tilt oppose … Read moreDifference between Anschutz and Sperry gyro

Damping. Damping in tilt, Damping in azimuth, North settling North settling:To get North settling, further precession is applied.This method is called Damping.Damping can convert north seeking device into north settling device.Damping can make North end of spin axis to settle in or near to meridian. Free gyroscope=(tilt+ drift)North seeking=(tilt+drift+gravity control)North settling=(tilt+drift+gravity control+Damping) Two methods of … Read moreDamping.

Operating principle of gyro repeater system Mechanised compass card.Driven by stepper motor. Construction:Consists of transmitter and receiver unit.Each unit consists of primary rotating rotor.Three secondary coil are located at 120 degrees interval on stators.Transmitter rotor is driven by azimuth gear of gyro. Working principle:AC is supplied to transmitter rotor and three secondary coil to produce … Read moreOperating principle of gyro repeater system

How free gyroscope is made north seeking under influence of gravity control? To get gyro compass, free gyroscope is made:North seeking.North settling. North seeking:To get north seeking, gravity is used to apply force/torque.So, North end of spin axis will precess.This method is called gravity control.Gravity control can convert trace out circular path into elliptical path.Gravity … Read moreHow free gyroscope is made north seeking under influence of gravity control?
