Abstract
Det beskrives en fremgangsmåte for kvadraturbiaskompensering i et coriolisgyroskop, hvilken resonator (1) er i form av et koblet system omfattende en første og en andre lineær oscillator (3, 4), og kvadraturbiasen for coriolisgyroskopet blir bestemt. Et elektrostatisk felt blir produsert ved å variere den innbyrdes justeringen av de to oscillatorene (3, 4) med hensyn til hverandre, hvor justeringen (styrken) på det elektrostatiske feltet blir regulert slik at den bestemte kvadraturbiasen er så liten som mulig.
