Where m is the mass of the object, v its velocity and

is the angular rate of the rotating coordinate

system.

system has got an electrically actuated oscillating mechanical structure, called primary frame (m).

force, a part of the frame - called the secondary frame - is designed to allow a motion as a reaction

to the applied Coriolis force. This synchronous motion is sensed electrically by a capacitive readout

circuit.

The gyroscope is a vibratory system with two orthogonal vibrating frames: the primary actuated

vibrating frame and the secondary sensed vibrating frame.

Zero Rate Output (ZRO) Drift

The bounds within which the circuit output signal may vary as the temperature varies across the

operating temperature range with no applied angular rate.
