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.

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.
How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
How do you eliminate local attraction?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
How do you charge gyro s1o7?
The Gyro S107 is a toy helicopter. In order to charge the S107 you will need a USB cord. You can charge the helicopter on a computer if you choose to. The remote control takes batteries and is not rechargeable.
What is the moveable bar in a compass called?
A compass magnet or a compass needle.
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
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 did Elmer Sperry invent?
Most notably, the gyro compass.
Instrument used for taking bearings by the use of gyro compass?
Pelorus
What is the advantage of gyro compass?
its getting to ship , wiring of the line of tube
How minutes in one degree of gyro compass?
There are 60 minutes in 1 degree.
What is the difference between gyro and directional gyro?
The term Gyro refers to any Gyroscope (Space,Earth,Tied or Rate) whereas Directional Gyro is typically a Tied Gyro which is used in Aircraft for the purpose of Heading reference in DGI (Directional Gyro indicator) because it does not suffer any errors like magnetic compass.
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
What is gyro repeater?
a navigational compass, under the control of a gyroscope, that automatically indicates true north.
What happens to the damping when the settling time increases in a derivative error compensation?
increase
What does a magnetic compass do?
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
