Gyro Compass Quiz

What is a gyro compass used for?

• Measuring air pressure

• Navigation and determining the direction of true north

• Playing music

• Cooking food evenly

How does a gyro compass differ from a magnetic compass?

• The gyro compass is not affected by the rotation of the Earth.

• The gyro compass finds true north using gyroscopic precession.

• The gyro compass points to magnetic north.

• The gyro compass uses Earth's magnetic field to find north.

What are the advantages of using a gyro compass over a magnetic compass?

• It is unstable in rough seas

• It provides true north direction, stability in rough seas, and independence from magnetic interference.

• It gives false north direction

• It is affected by magnetic interference

Explain the working principle of a gyro compass.

• The gyro compass works on the principle of electric charge.

• The gyro compass works on the principle of gyroscopic precession.

• The gyro compass works on the principle of magnetic attraction.

• The gyro compass works on the principle of gravitational pull.

What are the main components of a gyro compass?

• gyroscope, gimbal system, compass card

• clock, barometer, altimeter

• steering wheel, throttle, brake pedal

• map, ruler, protractor

What are the limitations of a gyro compass?

• Gyro compasses are easily affected by magnetic interference.

• Gyro compasses are only accurate in certain latitudes.

• Gyro compasses are expensive and require regular maintenance.

• Gyro compasses are not suitable for use in small vessels.

How is the accuracy of a gyro compass maintained?

• Exposure to extreme temperatures

• Regular cleaning with water and soap

• Periodic calibration and adjustment

• Shaking vigorously before each use

What are the different types of gyro compass errors?

• Up and down turning error, altitude error, and azimuthal error

• North and south turning error, latitude error, and quadrantal error

• Clockwise and counterclockwise turning error, equator error, and tangential error

• East and west turning error, longitude error, and meridional error

Explain the concept of north-seeking gyro compass.

• A gyro compass relies on GPS signals to determine direction

• A gyro compass uses magnets to find true north

• A gyro compass is a type of compass that finds true north using a fast-spinning rotor and the rotation of the Earth.

• A gyro compass is a type of compass that points towards the South Pole

What are the applications of gyro compass in modern navigation systems?

• Records temperature data

• Calculates water depth

• Measures wind speed

• Provides accurate and stable directional information
