Method of calibrating a scale factor of an axially symmetrical vibrating rate gyro.

摘要

Method of calibrating a scale factor of an axially symmetrical vibrating rate gyro operating by applying a control signal amplitude (CA) and a control signal precession (CP) in a vibrating body vibrated at a frequency determined, characterized in that it comprises a step prior calibration consisting in calculating a reference ratio of gains between an engine gains (Gmx) in a first direction and engine gain (Gmy) in a second direction in modal quadrature with the first direction and storing the reference relation of gains and a calibration step consisting in calculating a value for a measurable magnitude associated with the scale factor as a ratio of proportionality that includes the reference relation of gains and calculate a factor scale corrected from the value of measurable magnitude and the stored reference ratio of earnings.
