The invention concerns gyrometric measurement compensated as a function of the instantaneous internal temperature of a mechanical resonator in a gyrometric measurement device comprising a loop controlling the amplitude of the resonator vibration and a gyrometric loop delivering a gyrometric signal (S); the gain control (P) of the loop 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 between the values of the gyrometric scaling factor (Fe) and the gyrometric bias (S0) and the values of the gain control signal (F), that is F(P) and Q(P) respectively; in operation, the following operations are carried out: P→F(P), P→Q(P), and Ω′est=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.
