Abstract
Inertial measurement units attached to a non-rigid body may measure a common motion event when the body changes direction of travel. Acceleration measurements made by the inertial measurement units of the event are used to determine a common reference direction which in turn can be used to derive, individually for each inertial measurement unit, a new orientation intended to be a better representation of the actual orientation of the inertial measurement unit.
