Abstract

Fremgangsmåte for å kompensere driften til et hjelpemiddel for posisjonsmåling som er montert på et objekt, slik som et skip eller et annet befordringsmiddel, som omfatter minst ett gyroskop (6) for å måle objektets rotasjon rundt en akse og minst ett akselerometer (3) for å måle to gjensidig perpendikulære komponenter av tyngdeakselerasjonen som en konsekvens av orienteringen til objektet som angår tyngdeakselerasjonen langs to gjensidig perpendikulære retninger, som sammen tilsvarer objektets rotasjon rundt ovennevnte akse. Foreliggende oppfinnelse er karakterisert ved at det utgående signalet (4) fra akselerometeret er lavpassfiltrert, ved at det utgående signalet (7) fra gyroskopet er lavpassfiltrert, ved at disse to signalene blir sammenlignet og at det utgående signalet (7) fra gyroskopet (6) blir kompensert ved å anvende et utgående signal (4) fra akselerometeret (3) slik at deviasjonen til det utgående signalet (7) fra gyroskopet (6) på grunn av drift blir minket eller eliminert, og ved at det på denne måten produserte, kompenserte signalet (16) utgjør et utgående signal fra gyroskopet (6).
