Claim 7:
8. A system for capturing the motion of a body of interest, comprising:
a processor and a memory configured to provide computer program instructions to the processor to execute functions of components;
a motion dataset accessing component for accessing a plurality of motion datasets including timestamped motion data points, each of the plurality of motion datasets being associated with a respective motion sensing unit at which timestamped motion data points of that motion dataset are generated, wherein each of the plurality of motion sensing units is configured to be in physical contact with a different part of a body of interest and includes a plurality of disparate sensors and wherein each motion dataset includes timestamped motion data points from each of the plurality of disparate sensors which relate to motion of that motion sensing unit and global navigation satellite systems-based motion data points;
wherein each motion sensing unit includes a satellite network sensor arranged to receive signals transmitted from a global or regional navigation satellite systems network and wherein each timestamped motion data point is timestamped at the motion sensing unit at which it is generated using a clock time that is synchronized across the plurality of motion sensing units using the satellite systems network;
a correction component including:
a reference dataset accessing component arranged to access a reference dataset including reference data points having been generated at a base unit having a fixed position; and
an error correcting component arranged to use the reference dataset to correct errors introduced into the motion datasets to enhance precision of the global navigation satellite systems-based motion data points;

a processing component for processing the timestamped motion data points to generate a kinematic model which describes motion of the respective parts of the body of interest; and,
a model outputting component for outputting the kinematic model.
