Zusammenfassung:	A posture measurement apparatus and method is described. The posture measurement system includes a wearable sensor leader node comprising a UWB transceiver coupled to at least two antennas and one or more wearable sensor follower nodes each comprising a UWB transceiver coupled to one antenna. A first UWB signal is transmitted from the wearable sensor leader node to the one or more wearable follower sensor nodes. A second UWB signal is received by the wearable sensor leader node from each follower sensor node in response to receiving the first UWB signal. A time-of-flight value of a signal transmitted between the wearable leader sensor node and the wearable follower sensor node is determined from the first UWB signal and the second UWB signal. An angle of arrival value is determined from the second UWB signal. The body posture can be determined from the time-of-flight and angle-of-arrival value.
