摘要： The invention concerns a temperature-compensated accelerator measurement using two vibrating resonators whereof the frequencies (f1, f2) are measured, then used for determining (18, 19) the most probable temperature value (T) based on the sum f1+f2 and on a pre-established correlation (14) between the temperature and the sum f1+f2; and finally based on the determination (20) of the amount f1-f2 of the weighted temperature value, calculating (21) the temperature compensated value of the acceleration (η).
