Gyro Compass:
Reference point is true north.
It requires constant power supply.
Can be connected with large amount of equipments which require compass feeding.
Errors: high or low.
Equipment errors – wondering
error, permanent error, latitude
error, speed error.
It can be used near the earth’s magnetic poles.

Magnetic Compass:
Reference point is magnetic north.
It does not require constant power supply.
It is not possible to feed magnetic compass to any number of equipments.
Errors: deviation and variation.
Equipment errors – deviation and variation.
It can not be used near the earth’s magnetic poles.
At higher latitude, magnetic compass becomes inaccurate.
