<p>The invention concerns gyrometric measurement compensated as a function of the instantaneous internal temperature of a mechanical resonator (1) in a gyrometric measurement device comprising a loop (3) controlling the amplitude of the resonator vibration and a gyrometric loop (13) delivering a gyrometric signal (S); the gain control (P) of the loop (3) varies as a monotonous function, preferably increasing and of the first order, of the internal temperature of the resonator in a given range of temperature; during a calibrating step, a correspondence is established and stored (17) between the values of the gyrometric scaling factor (Fe) and the gyrometric bias (S<SUB>0</SUB>) and the values of the gain control signal (P), that is F(P) and Q(P) respectively; in operation, the following operations are carried out: P ? F(P), P ? Q(P), and O'<SUB>est</SUB> = F(P) .S + Q(P) which is a more precise analog estimate, compensated as a function of the internal temperature of the resonator, of the mechanical rotation of the sensitive axis of the resonator (1).</p> |
