This error is present in a compass which is damped in tilt. A compass damped in tilt always settles east of the meridian and above the horizon in NH, and vice-versa. Its magnitude depends on the observer's latitude, Sin( error ) α Tan( latitude )
At equator, the error is nil. The error is eastward in all northernly latitudes, and vice-versa.
For the purpose of damping error, a latitude rider / adjuster is provided with the gyro compass which shifts the lubber line equal to the amount of error in the appropriate direction.

What are the parts of gyro compass and its function?
A gyro compass consists of a spinning gyroscope, a compass card, and a correcting mechanism. The spinning gyroscope maintains its orientation in space and serves as the reference point for navigation. The compass card aligns with the gyro's axis to indicate the heading of the vessel. The correcting mechanism adjusts for errors due to the vessel's motion to provide accurate heading information.
Is a compass a magnet?
Compass is a device which is used to see directions previously. Compass consists of a Magnet freely suspended . A free Magnet always shows Geographical North and Geographical South. So Compass consists of a Magnet and a Aluminium pointer showing east and West direction.
What is damping ratio in control system?
Damping ratio in a control system is a measure of how fast the system returns to equilibrium after being disturbed. It indicates the system's ability to dissipate energy and reduce oscillations. A higher damping ratio results in a faster and smoother response with less overshoot.
How does surface area affect damping of an oscillation?
Increasing the surface area of an object can lead to increased air resistance, which in turn can increase the damping of an oscillation. This is because the increased air resistance absorbs more energy from the oscillation, causing it to lose its amplitude faster. Therefore, objects with larger surface areas tend to experience greater damping of their oscillations.
What is damping factor in control systems?
The damping factor in control systems is a measure of how fast a system's response oscillations decay after a disturbance. It quantifies the system's ability to resist oscillations and stabilize quickly without sustained oscillations. A higher damping factor indicates a more stable and faster-responding system.
Who invented the gyro compass and Gyroscope?
Elmer Ambrose Sperry was the inventor of the gyro compass and gyroscope.
When is the annunciator of a remote indicating compass system used?
For synchronising the magnetic and gyro compass elements For synchronising the magnetic and gyro compass elements
Instrument used for taking bearings by the use of gyro compass?
Gyro repeater is an instrument used for taking bearings by the use of a gyro compass. It displays the heading information provided by the gyro compass, allowing for accurate and reliable navigation on a vessel.
How does a gyro compass work?
Rather than type a long answer - see the related link from Wikipedia for their entry on a gyro-compass.
What is the power source of a gyro compass?
A gyro compass is powered by electricity, typically from the ship's electrical system. The gyro compass relies on the principle of a continuously spinning gyroscope to maintain its orientation and provide accurate heading information.
What is the reaction of a gyro compass to an applied force?
When a force is applied to a gyro compass, it will try to maintain its alignment in space and resist external influences due to its gyroscopic properties. The gyro will precess in response to the force, causing the compass card to tilt or rotate. Ultimately, the gyro compass will seek to stabilize itself and align with the true north once the external force is removed.
What did Elmer Sperry invent?
Most notably, the gyro compass.

The correcting mechanism adjusts for errors due to the vessel's motion to provide accurate heading information.
What is the advantage of gyro compass?
its getting to ship , wiring of the line of tube
What is deviation gyro course from magnetic course?
Deviation refers to the error in a ship's compass readings caused by magnetic fields from onboard electrical equipment and metal structures, leading to a difference between the gyro course (the heading indicated by a gyroscopic compass) and the magnetic course (the heading indicated by a magnetic compass). This deviation can cause navigational inaccuracies, making it essential for navigators to account for it when plotting courses. The difference between the gyro and magnetic courses is crucial for precise navigation, especially in areas where magnetic anomalies may exist. Regular calibration and adjustment of the compass systems can help minimize these discrepancies.
How minutes in one degree of gyro compass?
There are 60 minutes in 1 degree.
What is the different between a magnetic and gyro compass?
A magnetic compass uses the poles of our planet to stay in alignment. A Gyroscopic compass is set to a particular direction and tends to try to stay that way. After time, even the best Gyro will start to precess (move). This means the you will need to compare your Gyro to the magnetic every 15 minutes or so. Some modern gyroscopic compasses are capable of auto resetting to do this update automatically
