Primary and Secondary Frame
In vector notation the Coriolis force FCoriolis is given by:
(
)
×
=
v
m
F
Coriolis
2
Where m is the mass of the object, v its velocity and
is the angular rate of the rotating coordinate
system.
To create a Coriolis Force (FCoriolis), a movement or velocity (v) must be induced. The gyroscope
system has got an electrically actuated oscillating mechanical structure, called primary frame (m).
When the gyroscope rotates ( ) a Coriolis force FCoriolis acts on this frame. To measure the Coriolis
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.
