Described herein are methods and systems for determining a relative position of different portions of a hinged device. Motion sensor data from sensor assemblies of each portion is fused to relate the device portions to a world frame. An angular orientation between the device portions is determined with respect to the hinge axis and accumulating sensor measurement errors are compensated by constraining determined axes of the sensor assemblies using the motion sensor data and known relationships between physical axes of the sensor assemblies and the mechanical hinge, such that the determined axes of the sensor assemblies are aligned along the hinge axis.
