The method can include monitoring a plurality of rate-of-turn samples, from the inertial sensor, in a sequence over time, wherein each of the plurality of rate-of-turn samples includes substantially the same actual bias value that is included in each of the plurality of other rate-of-turn samples. The method can include estimating the bias as a weighted average of the plurality of rate-of-turn samples. The method can include determining an adjusted rate-of-turn sample by subtracting the bias from an instant rate-of-turn sample of the plurality of rate-of-turn samples. The method can include putting out the adjusted rate-of-turn."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rate-of-turn bias estimation for marine navigation","description":"An example includes a method to estimate a bias affecting an inertial sensor.
