| Abstract: | In order to reduce the course error and enhance the heading accuracy of electromagnetic controlled gyrocompass, after analyzing the measured data of a certain electromagnetic controlled gyrocompass, an error model was brought forward based on the least square method. The model parameters were estimated. Practical examination indicates that this model is helpful to achieve a better effect on compensating the course error. |
