Abstract
The invention relates to a gyroscope comprising at least one mass capable of vibrating along an x axis at a resonant excitation frequency Fcapable of vibrating along a y axis perpendicular to the x axis, at a resonant detection frequency F, under the effect of a Coriolis force generated by a rotation about a z axis perpendicular to the x and y axes. It includes, connected to the mass or masses, a feedback control loop for controlling the resonant frequency Fso that Fis equal or practically equal to Fthroughout the duration of use of the gyroscope.
