Abstract:
A method and system for tracking and updating bias in an inertial sensor by determining a maximum bias drift and a noise band for a sensor, determining a prior bias value of the sensor, and measuring a current bias value of the sensor. The method and system can further include calculating a bias difference between the prior bias value and the current bias value, and updating the prior bias value with the current bias value if the current bias value is within the noise band and the bias difference is less than or equal to the maximum bias drift.
