Claim One:
1. A method of calibrating a motion capture system having a plurality of transmitters communicably linked to at least one receiver for determining position of the plurality of transmitters, the method comprising: providing an estimate of the topology of the receivers; collecting a first dataset D 1 of time of arrival measurements using the transmitters placed in significant proximity to the one or more receivers to obtain a first estimate of calibration parameters; collecting a second dataset D 2 based on one or more of the transmitters moving through a volume of interest; using the dataset D 2 and the first estimate of calibration parameters to calculate a trajectory of the transmitter for each transmission instance to derive an initial estimate of the trajectory of the transmitter; and calculating a final set of calibration parameters based on the first estimate of calibration parameters and the estimated initial trajectory.
