Abstract (en)
[origin: WO2013033756A1] Inertial sensors are typically mounted at an angular offset relative to a chassis, such as a vehicle chassis or electronic device chassis. This offset can influence the measurements of the angular orientation of said chassis derived from inertial sensors. There is provided a method of determining a sensor orientation offset relative to a chassis by obtaining a first inertial sensor measurement, rotating the chassis approximately 180°, obtaining a second inertial sensor measurement; and then determining the offset from the two inertial sensor measurements.
