There is provided a method of sensing a rotation rate using a vibrating structure gyroscope, said gyroscope comprising an electronic control system comprising one or more control loops. At least one of said control loops comprises a filter having a variable time constant and the method comprises the steps of determining or estimating a characteristic of the vibrating structure of said gyroscope and adapting or varying the time constant of said filter with the determined or estimated characteristic of said vibrating structure. A system for sensing a rotation rate using a vibrating structure gyroscope is also provided. The characteristic may be the frequency, Q-factor or bandwidth of the vibrating structure and determining the characteristic may also comprise measuring the temperature of the structure. The filter or control loop may comprise a transfer function that is proportional or correlated to the characteristic. |
