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.

A gyro compass is a type of non-magnetic compass that uses a gyroscope to find true north, rather than magnetic north. It operates on the principles of angular momentum and gyroscopic inertia, allowing it to maintain a stable reference to the Earth's rotation. Gyro compasses are commonly used in marine navigation, aviation, and by ships and submarines, as they are unaffected by magnetic fields and provide accurate heading information. Unlike traditional magnetic compasses, gyro compasses require electrical power and can take some time to stabilize after being powered on.
North-seeking gyro is a gyro with damped precession such that it will align itself parallel to the Earth's spin axis.SPT North-seeking GyroTracer incorporates the very latest technological advances, which makes it the best gyroscopic surveying instrument for the mining and Oil & Gas industries that need to ensure repeatable fast, reliable and precise downhole survey data as well as time saving and the highest return on investment.SPT north seeking gyro is highly accurate, extremely reliable downhole directional survey and orientation tool that uses gyro compassing method to determine direction.
If you mean the difference between a compass and a compass rose: The compass is the complete instrument. The compass rose is the degree wheel printed under the needle.
Elmer Ambrose Sperry was the inventor of the gyro compass and gyroscope.

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.
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.
Apps can use the compass to determine the phone's current direction. This is useful for maps applications, GPS, or anything else that might need to know the current direction.
Most notably, the gyro compass.
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.
The disadvantages of using a compass for surveying is that readings are often inaccurate (accuracy dependent on size and graduations of compass, it is easily disturbed by effects of local magnetic attraction
