What is the definition of gyrocompassing?

The use of a (non-magnetic) gyroscopic compass to determine heading with respect to North.

The Anschütz gyrocompass enabled changes in the direction (heading) of the vessel to be observed without using a magnetic compass. Gyrocompassing, as it became known as, can be attained in several ways; for example, surrounding the gimbal with a degree graduated ring enables rotation of the gimbal to point to the new direction (much like a magnetic compass needle). Another means is to trap the gimbal and measure the torque generated by the gyroscope when its direction changes, in order to calculate the rotational movement.
