Abstract
Vibrating structure gyrometer with at least one tuning fork, produced by micro-machining from a thin plate, the said tuning fork comprising a pair of mobile inertial assemblies (EIM, EIM) linked by a coupling assembly (). A tuning fork comprises two controlled electrodes (') for equilibration of the sense resonator and electrostatic adjustment of the frequency of the sense resonator along the sense axis y which are respectively associated with the two mobile inertial assemblies (EIM, EIM) of the said tuning fork, and control means (UCE) adapted for applying two respective continuous electrical voltages Vand Vto the said two electrodes (′) simultaneously satisfying the relations:
