VIBRATING GYROSCOPE CALIBRATION

The method involves obtaining a modified command to be applied to an operational parameter e.g. amplitude, of a gyroscope by introducing a sinusoidal disruption in a current command of the gyroscope (11), and applying the modified command as the current command to the gyroscope (12). A measurement v...

Zusammenfassung:The method involves obtaining a modified command to be applied to an operational parameter e.g. amplitude, of a gyroscope by introducing a sinusoidal disruption in a current command of the gyroscope (11), and applying the modified command as the current command to the gyroscope (12). A measurement value resulting from the application of the modified command is determined (13), and a correction value of the operational parameter is identified (15) based on a correlation (14) between the measured value and the modified command. The value is applied to measurements provided by the gyroscope. An independent claim is also included for a gyroscopic system.
