Abstract

Det beskrives en fremgangsmåte for å bestemme nullfeilen for et coriolisgyroskop (1'), hvor resonatoren (2) for coriolisgyroskopet (1') har egnede forstyrrelseskrefter påført den slik at minst én naturlig oscillering av resonatoren (2) blir stimulert, som avviker fra den stimulerende oscilleringen og fra den målte oscilleringen for resonatoren (2), og en endring i et målt signal som representerer den målte oscilleringen og resultater fra stimuleringen av den minst ene naturlige oscilleringen blir bestemt som et mål på nullfeilen.
