Claim 9:
10. A system including a motion sensing unit for capturing the motion of a body of interest in a motion dataset and configured to be in physical contact with a part of the body of interest, the motion sensing unit comprising:
a plurality of disparate sensors for generating timestamped motion data points from each of the plurality of disparate sensors which relate to motion of the sensing unit for inclusion in the motion dataset;
a satellite network sensor for receiving a satellite network signal including timing information and having been transmitted from a global or regional navigation satellite systems network for providing global navigation satellite systems-based motion data points for inclusion in the motion dataset;
a clock synchronisation component for using the satellite network signal to synchronise a local clock time maintained by the motion sensing unit with clock times of a plurality of other motion sensing units in a sensor network;
a timestamping component for timestamping the motion data points to generate timestamped motion data points; and,
a providing component for providing the motion dataset including the timestamped motion data points to a computing device,
wherein the motion dataset is provided to the computing device for processing together with motion datasets from the other motion sensing units in the sensor network to generate a kinematic model which describes motion of the respective parts of the body of interest, including correcting errors present in the motion datasets using a reference dataset including reference data points having been measured at a base unit with a fixed position to correct errors by applying real time kinematic techniques to enhance the precision of the global navigation satellite systems-based motion data points.
