Abstract
There is provided a method and system of recalibrating a sensor, preferably by determining a sensor bias for an Inertial Measurement Unit (IMU) in a vehicle. The sensor bias is determined by taking a measurement from the IMU at a first orientation, and then taking a second measurement from the IMU at a second orientation that is rotated approximately 180° from the first orientation.
