RATE-OF-TURN BIAS ESTIMATION FOR MARINE NAVIGATION |
摘要 |
An example includes a method to estimate a bias affecting an inertial sensor. 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. |
