Beschreibung
Zusammenfassung:	A method for determining centripetal accelerations of pivotally coupled rigid bodies arranged in a series, where the series includes a rigid body arranged between a previous rigid body and a next rigid body, includes determining the centripetal acceleration of the next rigid body and the centripetal acceleration at an inertial measurement unit (IMU) coupled to the next rigid body based on measurements and calculated parameters from the rigid body and the next rigid body. The centripetal acceleration of the next rigid body and the centripetal acceleration at the IMU coupled to the next rigid body are determined without using measurements or calculated parameters from the previous rigid body.
