Abstract (en)
[origin: WO2010054814A1] Method for characterizing Coriolis gyroscopes, in which the interaction of the system comprising force transmitters, a mechanical resonator and excitation/read oscillation taps is represented as a discretized coupled system of differential equations, wherein the variables of the system of equations represent the force signals passed from the force transmitters to the mechanical resonator and the read signals read from the excitation/read oscillation taps, and the coefficients of the system of equations contain information relating to the linear transformation which maps the force signals to the read signals, the coefficients are determined by measuring force signal values and read signal values at different times and are inserted into the system of equations, and the system of equations is numerically resolved according to the coefficients, and the coefficients are used to infer undesirable bias properties of the Coriolis gyroscope which distort the rate of rotation of the Coriolis gyroscope.
