Abstract
A system for determining a heading of a vehicle is disclosed. The system includes a magnetometer configured to generate a magnetic heading output signal, and one or more rate gyros configured to generate a gyro angular rate output signal. The system may further include a controller configured to determine a magnetometer heading rate based on the magnetic heading output signal and a gyro heading rate based on the gyro angular rate output signal. The controller may calculate a difference value between the magnetometer heading rate and the gyro heading rate. If the difference value is above a difference threshold value, the controller may calculate an integration value between the magnetometer heading rate and the gyro heading rate, report a positive magnetometer error state if the integration value is above an integration threshold value, and report a negative magnetometer error state if the integration value is below the integration threshold value.
