Sensors, often attached to the gimbal frames or the spinning rotor itself, detect the minute angles and rotations. When the rotor inside the device spins at high speed, it possesses angular momentum, a quantity that depends on the mass of the rotor, its speed of rotation, and the distribution of that mass around the axis.

Physics dictates that a body with angular momentum will resist any external force attempting to change the direction of its spin axis. The spinning mass seeks to remain aligned with its original inertial reference frame, whether that be the surface of the Earth or the void of space, making it an invaluable tool for measuring orientation without relying on external landmarks.
While the concept might evoke images of complex spacecraft navigation, the basic mechanism operates on principles that govern everything from a child’s spinning top to the stabilization systems on massive ships. This device, often consisting of a spinning wheel or rotor within a set of rings, leverages the principle of conservation of angular momentum to resist changes to its axis of rotation.

This predictable reaction is the key to translating the device's inherent stability into measurable data. The interaction between the spinning rotor and these movable mounts introduces a secondary effect known as precession, where applying a force to the spinning object results in a movement 90 degrees further in the direction of rotation.
