What is Gyroscope ?
A gyroscope is a devise that can be used to maintain orientation based on the principles of angular momentum. It is a mechanism by means of which a rotor is journaled to spin around an axes. A gyroscope can be considered as having three axes.
The gyro effect is a couple (a moment, a torque - call it what ever you like) that results from the rate of change in direction of the angular momentum of the wheel.
Larger angular momentum change - shorter the time over which the change takes place - will result in - Bigger the Gyroscopic couple

The speed of precession of a gyroscope
The spin axis is the one defining the gyroscope strength. If the spin axis lies along a vertical line, the other two axes lie in the plane of the page. The gyroscope spins around its spin axis, the torque is applied to the primary axis and the secondary axis is the axis of precession. The spin axis gives rise to the gyroscopic effect.

A gyroscope comprising a rotor journaled to spin about one axis, the journals of the rotor being mounted in an inner gimbal or ring; the inner gimbal is journaled for oscillation in an outer gimbal for a total of two gimbals.
If a spinning gyroscope is placed such that its axis is horizontal and loosely supported from one end, the gyroscope does not fall. It rather maintains its horizontal axis and the unsupported end starts moving in a circular manner about the horizontal axis. The resultant rotation is perpendicular to the gravitational torque and the axis of rotation. The speed of precession of a gyroscope inversely varies with its angular momentum.
