摘要： A gyroscopic system comprises at least four vibratory gyroscopes capable of changing vibration position. A first measurement is provided by a gyroscope to be calibrated and a second measurement is provided by a combination of the respective measurements from the other gyroscopes of the system, these first and second measurements being carried out along the same measurement axis. The determination (12) of a measurement drift value between the first measurement and the second measurement is followed by a command (13) to change the vibration position of the gyroscope to be calibrated to another vibration position and a drift value is again determined. The vibration position change command and the determination of a drift value are repeated (14) K times, K being a positive integer. Then, a drift model is generated (15) as a function of the vibration position of the gyroscope to be calibrated on the basis of the drift values obtained.

摘要： In a gyroscopic system comprising at least four vibratory gyroscopes, a first measurement is provided by said vibratory gyroscope to be calibrated, and a second measurement is provided by a combination of the measurements from the other vibratory gyroscopes of the system. At the level of the vibratory gyroscope to be calibrated, an initial command is applied in order to command a change in position from a first vibration position (θ1) to a second vibration position (θ2). A calibrated scale factor value of the vibratory gyroscope to be calibrated is then determined on the basis of a calculated value in relation to the change in position, based on the period of time during which the initial command is applied, the initial command, an angular difference between the first and second vibration positions measured according to the first measurement and an angular difference between the first and second vibration positions measured according to the second measurement.

摘要： A method and device of determining a speed of rotation of an axially symmetrical vibrating sensor. The sensor has a vibrating member associated with control electrodes and with detection electrodes for generating a vibration presenting an elastic line possessing periodicity of order n and having a position that is variable as a function of the rotation of the sensor. The method includes performing successive evaluations of the speed for a predetermined number of positions of the vibration relative to the electrodes. The positions are geometrically offset relative to each other and the vibration is moved from one position to another by applying a precession command using a pre-established scale factor. The method also includes determining a speed of rotation in function of the evaluations.
